The Advantages of Professional Sheet Metal Ductwork Design

October 15th, 2014

Your ductwork is an integral part of your HVAC system. As such, it should be designed for maximum efficiency and longevity. One of the best ways to ensure you achieve this, and more, with your ductwork, is to have sheet metal ductwork fabricated for your home. Having ductwork tailored to your home and HVAC system has a number of benefits, but without professional help, you could encounter ongoing problems down the road. For over 13 years, Air on Demand has been fabricating sheet metal ductwork for customers in Homestead, FL and all over the Miami area, and we can make sure you have a ductwork system designed and fabricated to last for years to come.

Why Should I Consider Custom Ductwork?

Here are some reasons custom ductwork can be a good choice for homeowners:

  • Helps distribute air to all rooms evenly
  • Helps to create a system with neutral air pressure, which is optimal for the operation of your system and your comfort
  • Helps your system to achieve its highest level of energy efficiency
  • Reduces wear and tear on your system
  • Helps improve indoor air quality

It’s All About Correct Calculation

When you hire a professional to create custom ductwork, the following items should be taken into consideration in order to create a ductwork system perfectly suited for your HVAC system and your home:

  • Correct heating and cooling calculations – by doing load calculations, your fabricator can correctly size the ductwork to ensure that your home receives the proper air load.
  • Creation of ducts that have the straightest route from your air handler to a given room – ductwork that has many turns can make it harder for your system to deliver the necessary air flow to your living spaces.
  • Have a matching return duct for every supply register – having matching supply and return ducts helps keep the circulation in your home optimal.
  • Properly secure seals with metal binding and mastic – ductwork that is properly sealed has significantly less air loss, which helps increase energy efficiency and indoor air quality, and puts less stress on your system.

Having the right ductwork for your home makes all the difference between being comfortable and energy efficient, and not. Call Air on Demand and schedule an appointment with one of our fabrication experts to see how custom sheet metal ductwork in Homestead, FL can help your home.

Warning Signs It Is Time for Commercial HVAC Replacement

October 8th, 2014

A professionally selected and installed HVAC system for your commercial building should last for many years with only minimal performance problems…provided that it receives routine maintenance and targeted repairs as necessary. However, any complex mechanical appliance will eventually reach a point where stress wears it down so much that continued repairs will only keep it running for short periods of time. The repair expenses plus the higher energy cost of running the HVAC system will make it imperative to have the old system replaced.

This is a big decision to make, and you will not want to make it lightly. To help you determine when it is time for a new installation of a comfort system for your company, call on the commercial experts at Air on Demand. We will take care of your heating and cooling in Doral, FL with commercial HVAC services of the highest quality.

Here are a few warning signs to watch for that will tell you it’s time to contact us for an HVAC system evaluation:

Hot or Cold Spots in the Work Place

One of the clearest signs that a heating and cooling system is starting to fail is when you or your employees notice spots in the office that are hotter or colder than they should be. Sometimes this indicates trouble in the thermostat; but if thermostat adjustments and repairs do not solve the problem, then you may have an HVAC system that is on its last legs and struggling to provide you with the level of conditioned air that it once did.

Escalating Utility Bills

You keep a close watch on all the bills for your company, so you will have a good idea what to expect to pay each season to heat and cool it. When these bills start to rise—and continue to rise—for no easily discernible reason, you should have professionals look into the issue to discover if the HVAC system has developed irreparable damage.

Numerous Repairs

Most HVAC systems will require the majority of repairs during the last two years of their service lives. When you find yourself calling for repairs a few times a year just to keep the system up and running, then you’re probably throwing away money on a heater or AC that will never again work at peak performance level. If any single repair for the system would cost half of the price of a replacement, it is more economical to opt for the replacement.

Our team at Air on Demand will see if your company will benefit from repairs or if you should arrange for a new installation. We can help with all the commercial HVAC services in Doral, FL necessary to keep your employees and customers comfortable and content.

The Compressor and Air Conditioning Repair

October 1st, 2014

It is never good news when one of the components in your home’s air conditioning system starts to fail or malfunction: no matter what is wrong with the AC, you need to have swift and skilled repair work done to fix it, or else the cooling system could suffer a full breakdown—or at the very least start costing more to run.

However, some components are more worrisome than others should they begin to show signs they need repairs. Perhaps the most vital mechanism in your air conditioner is the compressor; this component is at the center of the heat exchange process that allows the AC to cool down your home, and should it fail it can sometimes mean needing to replace the entire system. Keep a close watch for the signs below that could indicate the compressor is in trouble.

When you need air conditioning repair in Palmetto Bay, FL or the surrounding areas, contact Air on Demand. All of our technicians are NATE-certified to deliver you the highest quality repairs.

Signs of a Compressor That is Going Bad

  • Hard starting: When the compressor in the outdoor unit comes on, does it stutter and make the cabinet shake? That means the compressor is encountering difficulty starting, a condition known as “hard starting.” There are different possible causes for hard starting, but it often means that the compressor has become “tight” and its mechanical motion restricted. This may eventually lead to the compressor freezing in place, which will bring about an end to your air conditioner’s cooling ability. Always call for repairs right away when hard starting becomes noticeable.
  • Short cycling: The term “short cycling” refers to times when the compressor’s cooling cycle is cut off early and the compressor shuts down before it should…only to come back on a short time later and start the process over. Whatever is causing the short cycling (poorly-sized AC, frost along the coils, miscalibrated thermostat, etc.) it needs to be fixed soon because it will put immense strain on the compressor and possibly cause it to overheat.
  • Loss of cooling: Because the compressor is responsible for powering the heat exchange cycle that allows the AC to provide cooling, a drop in the air conditioner’s performance often warns that something has gone wrong with the compressor. Since any drop in cooling is a bad sign (and will make your home uncomfortable), you should call right away for technicians to investigate and see what might be the matter.

One of the best ways to avoid compressor troubles is with regular preventive maintenance that will see that the component isn’t suffering from increased stress or repair needs. Air on Demand offers an excellent maintenance plan that includes a 20% discount on all repairs and 5% on new equipment (on certain plans). Contact us today to find out more about how you can reduce your need for air conditioning repair in Palmetto Bay, FL.

Consider Going Ductless for Your New Air Conditioning Installation

September 24th, 2014

Is it time to replace your air conditioner, but you aren’t sure what system to choose? With so many choices available, it can be difficult to know which system is best for you. One option you may want to consider is ductless air conditioning. Ductless systems offer some benefits others don’t, including the ability to both heat and cool. The best way to know which system is best for your air conditioning installation in Miami is to work with an expert. Air on Demand has been helping customers with air conditioning installation, repair and replacement for years, and we can help you choose and install an AC system that is right for you and your home.

How Does a Ductless System Work?

As the name implies, ductless systems do not deliver cooling (or heating) via ductwork; instead, individual indoor blowers are used. The blowers are about 35” long and contain a small fan, evaporator coils and an air filter. The blowers are supported by an outdoor unit that is very similar to that of a traditional split-system AC. The outdoor unit contains a compressor and condenser, and can support up to 4 indoor blowers. The indoor blowers and outdoor unit are connected by a small conduit placed in an exterior wall that contains the refrigerant line, power cord and condensate pipe. Each blower operates individually, and when one is turned on, the air conditioning cycle begins.

What Are the Benefits of a Ductless System?

There are a few benefits of a ductless system worth considering when planning to install a new air conditioner:

  • Can offer both heating and cooling – a ductless system can use heat pump technology to provide both heating and cooling for your home.
  • Customized comfort – each blower operates independently, allowing you to customize your cooling as needed.
  • Energy efficiency – because you only use the amount of cooling you need, ductless systems can help improve energy efficiency. Also, ductless systems eliminate all energy efficiency problems that can originate from faulty ductwork.
  • Easy installation – indoor blowers can be mounted flush against walls or hung from ceilings, so installation is quite quick and easy.
  • No need for ductwork – as the name implies, you can have whole-home cooling without the cost and hassle of having to install ductwork.

With so many different types of ACs to choose from, it can be difficult to know what type of air conditioning is best for your installation in Miami. Call Air on Demand today and schedule an appointment with one of our installation experts.

Make Sure You Schedule Maintenance for Your Pool Heater

September 17th, 2014

With summer now over, you’re probably thankful that you have a pool heater installed to keep your swimming pool warm during the cooler weather. A properly installed pool heater will ensure that you receive the most use possible from your pool during the year, even through the winter.

Your pool heater, however, may not be ready for the work it will need to do. During the fall is an excellent time to schedule that important regular maintenance so the heater not only keeps the pool comfortable, but also won’t drain extra energy. Our team at Air on Demand offers quality maintenance service for pool heaters in Coral Gables, FL and the surrounding areas, so contact us today to arrange for your annual inspection and tune-up visit.

Why You Need Pool Heater Maintenance

A pool heater has maintenance needs similar to any home heating system: like furnaces, heat pumps, and boilers, a pool heater must have an annual check-up and inspection to see that it will work throughout the cooler months. Maintenance is also necessary to see that the pool heater lives up to its estimated lifespan.

Most pool heaters work through technology similar to that of a heat pump or air conditioner, and they need yearly service to see that their most crucial component—the compressor—is not in danger of burning out. Should a compressor burn out, the entire pool heater will usually need to be replaced. Electrical components in pool heaters will also start to wear down without maintenance, and will sometimes require replacements. Technicians take special care to investigate electrical components in a pool heater.

What Happens During Pool Heater Maintenance

When you contact us for a regular maintenance session for a pool heater, one of our skilled technicians will run through an 8-point checklist to see that the system works its best and does not require any repairs. The specific types of checks done with depend on the type of pool heater you have.

A technician will check on the refrigerant pressure, check and clean contacts, capacitors, the condenser coil, fan motors, and see that the compressor is working without extra strain. The technician will finish the session with a system efficiency test and a check on the temperature input and outflow. If anything appears amiss, the technician will advise you on repairs and parts replacement, and then help arrange for the work necessary.

Contact Us Today to Schedule Maintenance

If you haven’t had a tune-up and inspection for your pool heater in a few years, it is never too late to get started. Call Air on Demand today and ask about our maintenance services for pool heaters in Coral Gables, FL.

Why You Should Install a Pool Heater in Palmetto Bay, FL

September 10th, 2014

There are few home luxuries better than a swimming pool. During a sunny summer in Florida, a pool turns your home like a vacation spot, and any weekend day feels like a holiday. But what about the rest of the year? To enjoy the most days possible from your home’s pool, you should have a pool heater installed that broadens how much you can enjoy your pool.

It’s simple to have a pool heater installed: contact the professionals at Air on Demand. We specialize in pool heaters in Palmetto Bay, FL, and our installers will calculate the size and type of pool heater necessary to give you a year-round oasis in your backyard. We also offer pool heater replacement, repair, and maintenance services so you will also be able to enjoy a heated pool whenever you want it.

The Reasons You Should Install a Pool Heater

Direct sunlight on a pool during the summer helps warm up the water. However, the large surface area of a swimming pool allows heat from the water to rapidly escape into the air, so the temperature outside doesn’t have to drop far before the pool cools down to a level that makes it difficult to enjoy. A pool heater replaces the heat lost along the surface and maintains a pleasant temperature that allows you to relax in the pool on a cloudy or overcast day.

A pool heater will give you many more days to spend enjoying the luxurious pleasures of your swimming pool. With the generally mild fall and winter season in Florida, you could potentially use your pool every month of the year. And you won’t have to worry about exorbitant heating costs if you rely on professionals for the installation work. The technicians will help you select from a number of different models (electric resistance heaters, heat pumps) to match with the size of your pool (specifically its surface area), local temperatures, and the cost of power in your area so that your receive the most cost-effective heating system. And once the heater is installed, you can expect years of excellent service from it: when you multiply those years by the number of extra days you’ll be able to enjoy the pool annually, you will see the huge advantage of deciding on installing a pool heater.

The team at Air on Demand has many years of experience with sizing and installing pool heaters in Palmetto Bay, FL. Call us today for an appointment so we can look over your pool and find out what it needs for comfortable, year-round heating.

The Fashion of Wearing White and Labor Day

September 1st, 2014

You may have heard about the fashion faux pas of wearing white after Labor Day. In the present, this tradition is usually treated as old fashioned and a joke. Few people will criticize you for wearing white articles of clothing after the first Monday in September, or even take notice of it except to wonder why it was ever a major concern at all.

Where did this tradition of white clothing going out of fashion after Labor Day come from, and why did it fade away like colorful fabric washed in a hot load in the washing machine?

In general, white makes sense for the heat of summer. Light-colored clothing reflects away the radiant heat of the sun, instead of absorbing it the way dark colors do, so for thousands of years of human history people have preferred to wear white clothing during the hotter months.

However, the idea of white as strictly fashionable during the summer season only emerged in the nineteenth and early twentieth centuries—the time when the very concept of “fashion” began to spread across the Western Hemisphere.

It was only the highest level of post-Civil War society in the U.S. that strict and often bizarre rules for fashion controlled whether someone was in with the “in” crowd. Compared to our ideas of what’s fashionable today, the Czars of Style in the 1880s were true despots. Things as trivial as sleeve length could determine whether a woman in high society—no matter her level of wealth—was fashionable or a pariah.

Wearing white during the only summer, when it was common for weddings and outdoor parties, was only of these restrictive society rules. When the U.S. government made Labor Day a federal holiday in 1894, the Fashion Czars gained a definite cut-off point for when wearing white was no longer “acceptable” in the upper echelons of wealthy society.

For many decades, this rule only applied to a small number of millionaire socialites in a few big cities, but in the 1950s it reached general fashion magazines that were read around the country and started to affect more people.

But time eventually broke apart this odd rule, and during the 1970s fashion became more individual. Some fashion legends, like Coco Chanel, also purposely rejected the restriction and wore white throughout the year. Today, the “no white after Labor Day rule” is little more than an amusing gag to tease friends, and almost nobody takes it seriously.

Whatever you choose to wear after Labor Day (and if it’s white, we won’t tease!), everyone here at Air on Demand hopes you have a happy end of the summer and great plans for the fall!

Air Conditioner Problems That Can Happen When You Don’t Change the Air Filter

August 27th, 2014

The air filter in your AC may help you breathe more easily as it keeps unwanted pollutants like dust and bacteria out of the air. But if you don’t maintain your air filter, these particulates can build up over time and clog the filter. Not only will this affect the quality of the air, it may also prevent your air conditioner from working as it should. Sometimes, problems with your air conditioner may be solved by simply changing the filter. But when a clogged filter affects other components of your system, you should call a professional for air conditioning repair as soon as possible.

One problem that may be fixed by simply changing the filter is low efficiency. The indoor portion of your air conditioner uses a fan to suck in warm air from your home and remove heat from the air. However, your air conditioner will struggle with this process if a dirty filter blocks airflow to the evaporator coil. As your air conditioner works harder and runs longer to cool the air, your energy bills go up. Luckily, this problem may be solved by simply replacing the filter.

However, some problems will require the services of an air conditioning repair technician. If the indoor fan cannot blow enough air over the evaporator coil, it may begin to freeze. A frozen evaporator may mean you feel limited cooling from your air conditioner or no cool air at all. And if you attempt to fix the problem on your own by scraping off the coil, you may only make it worse. Low airflow can cause problems for your home and other parts of your air conditioner, so seek repairs as soon as you notice the signs.

Check with your manufacturer to find out whether your air filter can be cleaned or whether you need to purchase a replacement filter. You should clean or replace the filter about once a month, although this number varies depending on use.

To keep problems from occurring with your air conditioner, call Air on Demand for regular maintenance. However, if your air conditioner does run into problems, call us today for air conditioning repair in Doral, FL.

3 Benefits of Ductless Mini Split Air Conditioners

August 20th, 2014

Ductless air conditioning as an option for home comfort has taken off during the last two decades. Originally, ductless mini splits were used primarily for businesses (they are especially popular for restaurants) but their numerous benefits have made them impossible for homeowners to pass up.

If your home is right for installation of a ductless mini split AC, you should give the idea serious consideration. We’ll look at some of the advantages you can enjoy when your go ductless for cooling down your home.

Air on Demand installs ductless mini split air conditioners in Miami, FL. This is a complex job, and isn’t something you want to delegate to inexperienced amateurs (or attempt to do yourself) so contact our team when you think that ductless is your best choice.

3 of the Benefits of Ductless ACs

  • They also provide heat: Ductless air conditioners are actually ductless mini split heat pumps. That means they can provide heating as well as cooling. Heat pumps are excellent for Florida weather, since they work as well as any standalone air conditioner of comparable size and can ably handle our mild winters while in heating mode.
  • They help protect indoor air quality: One of the unfortunate problems with ductwork is that it collects dust, dirt, dander, and other contaminating particles, which is then blown out into your home’s air and recirculated. Only regular duct cleaning can prevent this. When you eliminate ducts with the installation of a ductless mini split, you take away this reservoir for pollutants and help keep your air healthier without the need for regular cleaning. If you have people with allergies or asthma living in your home, going ductless can make their lives much easier.
  • Energy savings: Ductless mini split heat pumps send conditioned air into your home through wall-mounted blower units, each which connects to the outside unit. Because you can individually control the blowers, you only have to send conditioned air to the parts of the house that need it. Unlike a central AC, you don’t have to cool down the entire house each time the system comes on, and this will lead to a reduction in your utility bills. You will also reduce the energy loss that can happen along the length of ductwork, increasing your savings.

Ductless mini splits are not right for every home: they work best for new construction, remodeling, add-on rooms, or for older and historic homes that lack the room for ducts. If you are unsure about installation, call the professionals at Air on Demand. We can look over your home and your current AC and determine if installing one of our ductless mini split air conditioners in Miami, FL is your best option for year-round comfort.

How Do Commercial HVAC Systems Differ from Residential Systems?

August 13th, 2014

Would you mow several acres of lawn with a push mower, or use a motorcycle for a family of 5? These are strong examples, but they demonstrate one of the key ways residential HVAC systems are different from commercial ones: size. While there are common, fundamental mechanics between commercial and residential systems, the systems are not the same. Working with professionals who have the knowledge and experience needed for commercial HVAC service is important for both you and your business. For over 30 years, Air on Demand has been providing commercial HVAC services in Pinecrest, and our trained technicians are available for any commercial repair you may need.

What Are the Differences?

As we stated above, one of the biggest differences between commercial and residential HVAC systems is their size. But there are others that are also important:

  • Many are packaged units – because commercial HVAC systems have to cover a great deal more square footage than the average household, they are often manufactured as one large unit called a packaged unit. These units are called packaged because all the components – the compressor, condenser and evaporator – are all housed in a single cabinet. This makes repair work easier because the components are more accessible.
  • Complex drainage – a commercial HVAC system covers large spaces; as such, the drainage system is far more complex than the simple condensate tray and drain you’ll find in a residential property.
  • Use of modular units – over the last few years, modular units have become very popular in the commercial HVAC industry due to their flexible nature. As businesses move in and out of spaces, cooling needs can vary; with a modular system, these needs can be met without having to re-design the cooling for that space. If less cooling is needed, one of the modular units can be removed; if more is needed, a modular unit can be added.

Having the proper amount of cooling is vital to your business. Do you really want to trust it to a company that doesn’t specialize in commercial HVAC services in Pinecrest? If you have been experiencing problems with your commercial HVAC system, call the professionals you can count on: Air on Demand.
