A Good Rule of Thumb for When to Replace Your Air Conditioner

Wednesday, November 19th, 2014

There are numerous “rules of thumb” when it comes to your home, including for the installation of appliances and whole-home systems. While rules of thumb can be good for small things like installing a window shade, they may not be great for bigger things, like replacing your air conditioning in Doral. This is because you may miss the inclusion of some important factors necessary for installing the right system for your home. The best rule of thumb you can use for installing a new air conditioner is to work with a trained professional from start to finish. Working with an expert helps ensure that you’ll find an air conditioning system that fits the needs of you and your home for the long-term, and the experts at Air on Demand can help you with every step.


Sizing is one of the most important aspects of any home system installation. Installing an air conditioning system that is too big can leave you feeling cold and clammy, and one that is too small may not cool your home adequately. Additionally, both situations put a great deal of stress and wear on your system, which can result in malfunction and breakdown. Performing a cooling load calculation is critical to determining what size AC you need, and there are several factors to consider aside from square footage, including:

  • Orientation of your home
  • Number of occupants
  • Floor plan
  • Number of rooms and stories
  • Number and types of windows and doors
  • Insulation levels
  • Daytime heat gain

Type of System

Once you know what size AC you need to cool your home, you have a decision to make on the type of system you want. Some current options are:

  • Heat pumps
  • Traditional split-systems
  • Ductless systems

Understanding how each type works and the benefits each can offer you is important to making an informed decision about your AC replacement.

Rules of thumb can be helpful for small household tasks, but when it comes to the installation of a new air conditioning system in Doral, it’s best to use the assistance of a trained expert. If you are ready for a new AC system, call Air on Demand and schedule an appointment with one of our installation experts.

Why You Need Pool Heater Maintenance This Fall

Wednesday, October 22nd, 2014

If you own a pool, you probably already know how much work it is to keep it in good condition. Pools require a lot of vacuuming, filtering, and fishing out debris to ensure an optimal swimming environment. One thing that not a lot of homeowners think about, however, is pool heater maintenance. After all, pools tend to see the most use during the summer, where heating is hardly necessary. As winter approaches, however, it behooves you to make sure that your heater is in good condition. Here are some of the reasons to conduct pool heater maintenance this fall.


Just like furnaces, boilers, and other home heating systems, pool heaters are most susceptible to breakdowns during periods of heavy usage. This is obviously going to be during the winter months, as very few people are going to want to swim in sub-fifty degree water. Fall maintenance ensures that your pool heater is in top working order right before you’ll be using it the most, decreasing the chances of an inconvenient and costly breakdown.


If a problem is discovered with your pool heater during regular maintenance, it usually isn’t that difficult or expensive to fix. Problems that are left alone, however, tend to get progressively worse until they cause a breakdown or other more serious issues. As is the case with other home maintenance, the longer you ignore potential problems, the worse they will get.

This is especially true in winter, where a broken pool heater makes your pool more or less unusable until you get it fixed. Pool repairs of any kind are rarely cheap, so by ignoring fall maintenance you also face the risk of a costly repair procedure.

A pool is a great thing to have as a homeowner. They provide exercise, entertainment, and relaxation year round, as long as they are kept in good condition. Don’t let yours incur problems that could have been avoided. Get your pool heater checked this fall.

If you haven’t had your pool heater checked yet this year, call Air on Demand. We offer quality pool heater services in the Doral, FL area.

Warning Signs It Is Time for Commercial HVAC Replacement

Wednesday, October 8th, 2014

*Air On Demand no longer offers commercial HVAC services – view a full list of our air conditioning services here.
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.

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

Wednesday, 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.

How Can a Ductless Air Conditioning Installation Save Me Money?

Friday, June 27th, 2014

Here in Doral, FL, you need a reliable air conditioner to keep your home cool all summer long. However, your current air conditioning system might be costing you a lot of money in the summer months. If your home AC system causes your energy bills to soar this summer, consider a ductless system to cut down on your energy consumption.

If you decide a ductless mini split system is best for you, contact Air on Demand for ductless air conditioning installation service.

What Is a Ductless Mini Split System?

A ductless mini split system provides a flexible solution for both cooling and heating your home. It’s divided into two parts: an outdoor compressor/condenser unit and one or more indoor units. Instead of using ducts throughout the home, multiple indoor air handlers can be installed in different rooms or zones to provide varied temperatures in each area.

The size of these indoor air handlers contrasts significantly with those utilized by central air units and heat pumps.

How Can a Ductless System Cut Energy Bills?

One way that ductless mini split systems help you to save money every month on your energy bill is by allowing you to control the temperature of each room. If your family is gathered in the living room, for example, you may choose to adjust the temperature in areas of the home that are not in use to cut cooling costs.

Another way a ductless system helps you save on your energy bills is by cutting potential energy loss associated with AC systems that utilize ducts. Faulty or leaky ductwork accounts for a large percentage of energy loss, forcing central AC systems to work harder to compensate and costing you more on your energy bills.

To start saving money on your energy bills with a ductless air conditioning installation, contact Air on Demand today!

3 Problems with Your Air Conditioning Fan That Require Repairs

Friday, May 23rd, 2014

The standard central air conditioning system in a home has two large fans. A blower in the inside cabinet draws warm air through the return vents and sends it across the evaporator coil, where it loses heat, and then moves it out into the ventilation system. The fan housed in the outdoor cabinet draws outside air across the condensing coil, where it releases heat.

As key mechanical components inside an air conditioner, the fans need to remain in top operating shape or else the performance of the system will be in jeopardy. If you notice a drop in airflow from your vents, feel insufficient levels of cooling, or hear loud striking sounds from the AC, don’t hesitate to call professional technicians to handle repairs. You’ll find the NATE-certified staff at Air on Demand ready to help you with your air conditioning in Doral, FL, no matter the trouble.

3 Repair Issues With AC Fans

  1. Broken fan belt: This is a problem for older air conditioners that still use blower fan belts. (More recent models use direct motors.) The fan belt is more susceptible to damage than other parts of the fan, and the intrusion of debris into the cabinet can sometimes cause the belt to break. The belt can also wear down from age, causing it to fray and tear apart. A loose belt will make a loud clanging noise in the cabinet, and a fraying belt will create a clicking sound, so call for repairs as soon as you hear anything unusual.
  2. Burnt out motor: The motor that runs the fan (either a direct motor or using a fan belt) can suffer from strain that will cause it to burn out and fuse the wiring inside the case. When this occurs, the fan will not move at all and the motor will need to be replaced. A motor undergoing excess stress will start to make screeching and grinding noises, and sometimes repair technicians alerted in time can repair them instead of replacing them.
  3. Bent fan blades: This trouble is more common for the outdoor blower because large debris such as stones and branches. Bent blades will begin to strike the fan casing and will rapidly inflict further damage to the air conditioner if not repaired. When you hear the sound of metal striking metal coming from the cabinet, call for repairs right away.

If fan problems are not fixed soon, not only will it risk further repair needs, the loss of airflow will impair heat exchange and threaten your supply of cool air. Opening the cabinet to fiddle with the fan on your own is not the way to handle the trouble, since you can potentially cause more issues with the unit. Instead, call Air on Demand and speak to our experienced staff. We will send out AC repair technicians who will take care of your air conditioner in Doral, FL so you will have the best airflow and performance from your AC for the rest of the summer. Give us a call today.

Air Conditioning Repair in Miami: Why Your Fan Won’t Stop Running

Tuesday, June 18th, 2013

In Miami, we tend to rely a bit more on our air conditioners than in most of the country. Because of the heat and humidity of the long cooling season, our AC is responsible for much of comfort we experience in our homes on a daily basis. That’s why it’s critical that we take care of any problems with its operation before they become major repairs or unnecessary replacements. One common problem that you may experience this summer is a fan that won’t stop running. While it seems like you would never want your AC to turn off these days, it should not run continuously. If one of the fans in your AC fails to shut off after the refrigerant cycle is complete, then you may have a problem worthy of professional attention. Call Air on Demand today for comprehensive air conditioning repair in Miami.

There are two basic fans in your AC. The outdoor unit contains an exhaust fan that pulls the outside air through the condenser coils, allowing the refrigerant to dissipate the heat collected in your home. Your AC’s other fan resides in the indoor unit. This is the blower motor that pulls in the warm air from within your house and sends it through the evaporator coils, which cools the air which is then circulated through your air ducts.

But like any mechanical component, there may come a time when your fans malfunction and they won’t turn off as they should. There are several potential reasons for this. First, it may be an issue with the control board on the AC itself, which is not communicating effectively with the motors. Your AC’s electrical system is an integral part of its operation. Alternatively, it could be an issue with the thermostat. If the latter is not sensing the temperature correctly, then it cannot communicate with the AC to turn off the fan.

Having trouble with your AC fan? Call Air on Demand for excellent air conditioning repair in Miami.

Miami Air Conditioning Tip: How to Protect Your AC System During a Thunderstorm

Monday, October 8th, 2012

Early fall is hurricane season in Florida, which means there’s always the likelihood that we’ll see many storm systems and severe thunderstorms in the coming weeks. At Air on Demand, we care about the safety of our customers, so we’ve provided some helpful tips on how to protect the AC system in your Miami home in the event of a thunderstorm. We’ve also covered some steps to take if you think your air conditioner has been hit by lightning.

  1. To protect your air conditioning system from damage during a lighting storm or other extreme weather conditions, turn it off completely. If lightning strikes your home, or anywhere nearby, it can damage the electrical controls.
  2. Consult the owner’s manual if you aren’t sure how to completely shut down the system. Or you can always call us if you aren’t sure how to turn off your AC system.
  3. Unplug all electrical devices to help protect all the electronic equipment inside your home.
  4. Don’t attempt to turn your air conditioner back on if there are still storms in the area.
  5. Once weather conditions are back to normal, you can turn your AC back on. Make sure the power is on and check your circuit breakers for any flipped switches.
  6. If you turn on your air conditioner and it isn’t working, check the thermostat to make sure that thermostat has power and is turned on properly. If not, turn it on, and lower the temperature enough for the fan to turn on. If this doesn’t work, check the breaker box again, or check the batteries on a battery-operated thermostat.
  7. If you’ve tried all of these steps and the AC or heat pump unit still won’t turn on, give us a call. We will send one of our technicians to your home as soon as possible to see if there’s been any damage from lighting and to get your system running again if possible.

Lastly, if your air conditioning system or heat pump has been damaged by lightning and needs to be replaced, check with your insurance company or read your policy to see if they will cover a system replacement or parts replacement.

The Miami AC technicians at Air on Demand will thoroughly check and test your system to ensure that any components damaged by lightning are fully repaired or replaced. Call any time for emergency air conditioner repairs.

Miami Air Conditioning Installation Tip: Why SEER Is Important

Monday, May 21st, 2012

Picking out a new central air conditioning system in Miami can be pretty complicated; there is a lot to take into account. You not only want an air conditioner that has the capacity to cool your home, but you also want a model that is energy efficient.

The SEER (seasonal energy efficiency ratio) that each central air conditioner has is a very important aspect to consider. SEER is a measure of the unit’s energy efficiency, which has a direct impact on how much you pay on your energy bills each month. The higher the SEER, the more energy efficient an air conditioner is.

However, very efficient air conditioners also tend be more expensive, so it’s important to weigh the energy savings compared to the initial cost. In order to figure out the difference in savings between air conditioners with different SEER ratings, you need to do a few calculations. An air conditioner with a SEER rating of 11 is approximately 7 percent more efficient than one with a SEER rating of 10. If you are spending $100 on your energy bill, upgrading to a SEER 11 air conditioner will save you $7. If your energy bills are higher (which they very probably are), that 7 percent will save you a lot more.

However, you probably won’t be upgrading from a SEER 10 to a SEER 11. Central air conditioners need to have an SEER of at least 14.5 to be ENERGY STAR qualified, and there are units with nearly twice that SEER rating! Those units can make a huge difference in your home’s energy use. Any new air conditioner you buy is probably going to be more energy efficient than your current unit, you just need to choose which model meets your homes needs and budget.

If you are interested in learning about the types of air conditioners that are available for your Miami home, give Air On Demand a call today!
