Upgrades to Consider with Air Conditioning Installation

Thursday, July 31st, 2014

Purchasing a new air conditioning system may be a big investment, but the upgrades you choose upon installation can save you a lot of money every month. Choosing to replace an older system may be a positive experience when you upgrade to an air conditioner with a high SEER or replace your older thermostat with a digital, programmable model, both of which are available when you choose air conditioning installation in South Miami with Air on Demand.

High SEER

If you need a new air conditioner, you can select a system with a high SEER, which means you’ll notice immediate savings. The SEER (Seasonal Energy Efficiency Ratio) is a measure of an air conditioner’s efficiency calculated by dividing the cooling capacity of an AC by its total energy consumption. This rating system is printed on the EnergyGuide of every air conditioning system. The efficiency of an air conditioner reduces over time, and newer systems generally have much higher SEERs than older systems.

Digital, Programmable Thermostats

Some people choose to keep their older thermostat with new AC installation, but if you’re holding onto a manual thermostat with dials and sliders, you may lose money and sacrifice some comfort. These thermostats are often difficult to read and calibrate, so you may never get the temperature set to where you want it. Furthermore, these thermostats may cost you. Even if you set the temperature only one or two degrees lower than you need it, you will spend much more on cooling costs than you should.

A new, programmable, digital thermostat can help save you money and can keep you more comfortable in your home. Digital thermostats are easier to read for greater accuracy, and programmable thermostats allow you to set the temperature to your preferences far in advance. Rather than keep the air conditioner on when you leave the house, you can set the thermostat to come on thirty minutes before you arrive to reduce energy consumption.

To install an AC in South Miami, ask the experts at Air on Demand which upgrades are best for your home. To see more energy savings with your new air conditioner, give us a call today!

What Is the Difference between Rooftop Units and Other ACs?

When it comes to commercial air conditioning, the great workhorses are rooftop units. People are accustomed to seeing rows of air conditioner cabinets along the top of office and retail buildings. Some commercial buildings still use “split” systems that are similar to the ones seen in residential housing, while restaurants and bars often use ductless heat pumps that send conditioned air wall-mounted blowers that are connected to an outdoor condenser. But the rooftop unit, because of its space saving quality and ease of service, continues to be the most popular for business use.

What actually differentiates rooftop units from other HVAC systems, aside from their location? We’ll look into this, and it may help you make the decision for what sort of heating and cooling system you want for your business location.

For detailed information on how rooftop units in Coral Gables, FL will work for your company, call Air on Demand and ask about commercial HVAC services today.

What Sets the Rooftop Unit Apart From Other ACs

Rooftop units are what are known as package units in the HVAC industry. A package unit is set apart from a split system, which is the common type of air conditioner/heat pump found in houses. A split system has an outdoor cabinet and an indoor cabinet with different sets of components. The outdoor cabinet has a compressor, fan, and a condenser coil; the indoor cabinet has a blower, dampers, air handler, and evaporator coil, and hooks into the ventilation system.

With a rooftop package unit, all the components are housed in one cabinet stored on the top of the building. Both sets of coils, to release and absorb heat, are in the cabinet along with the compressors and the fans. The unit connects directly into the building’s ventilation system to circulate the air.

Rooftop units can be configured either as air conditioners, or as heat pump capable of both heating and cooling. With installation of a humidistat on a rooftop unit, it can also control humidity and permit the ventilation of fresh air into the system; this is a benefit that split systems do not have, and it is a great asset for increasing indoor air quality.

Rooftop units come in an enormous array of types and sizes, and you will need to have professionals help you select the right unit or units to install for your business. The comfort of your employees, customers, and/or clients rests on making the correct decision for rooftop units in Coral Gables, FL, so make sure you have an experience commercial HVAC company handling the work for you: call Air on Demand for installation and AC repair in Miami. We carry Trane rooftop units from 1.5 tons up to 162 tons of cooling capacity.

How to Choose the Right Air Conditioning Installation Service

Tuesday, July 15th, 2014

If you need a new air conditioner in South Miami, FL, there’s no time to wait! You need to find an air conditioning installation service right away, but how do you choose the right one? Air conditioning installation is a delicate process, and you want to be certain your technician will be honest and dependable. The following guide can help you choose an AC technician that will do the job right.

Air conditioning installation is an intricate process that should always be handled by a professional. If your air conditioning system is not installed correctly, you may run into many costly repair issues later on or high energy bills. For example, if your AC unit is not sized properly for your home, your unit may have to work harder to keep you cool. This not only drives up energy costs, but also causes some parts to wear out sooner than they should, which means you’ll have to pay to replace them sooner than is necessary. For this reason, you should never attempt installation on your own.

The air conditioning installation service you choose should discuss pricing options with you during your scheduled estimate. Air conditioners are available within a number of price ranges. If you’d like to save energy every month, ask your AC technician if there is a system available with a higher SEER (Seasonal Energy Efficiency Ratio). A lower SEER may help you save on the initial cost of installation, but your energy bills may be higher every month.

Furthermore, the air conditioning installation technician you choose should discuss all of the different air conditioning systems available to you. Your technician should be willing to discuss ductless and central air conditioning options for homes with unique needs.

You should also choose an air conditioning installation service that offers repair and maintenance services as well. If your technician does a good job, you may choose to contact the company for future repairs. This will be easier for you and will help you be sure the technician knows the ins and outs of the particular system installed in your home.

Signs You Need to Call for Commercial HVAC Services

Thursday, July 10th, 2014

*Air On Demand no longer offers commercial HVAC services – view a full list of our air conditioning services here.
 
If your business is housed in a building with a properly installed HVAC system to provide heating and cooling, you shouldn’t encounter many problems with operating. However, because commercial systems are required to run for many hours—far more than any residential system—they will suffer from a large amount of wear and tear. Although regular maintenance will go a long way to alleviating this issue, you may still need to call in professionals to handles repairs.

There are some of the signs that you may need call on commercial HVAC services in Kendall, FL. Make sure that you contact a company with experience on heating and cooling businesses; this isn’t a job that anyone familiar with residential HVAC can handle. Look to Air on Demand and our NATE-certified technicians for the next time you need service to restore the comfort of your workplace.

Here Are Signs to Call for Commercial HVAC Services

  • Uneven temperatures: A common issue that can occur in commercial HVAC systems is trouble with the zone dampers and the thermostats. Commercial systems are larger than residential ones, and they need to use multiple thermostats to control a large number of zones. When people in the workspace start to complain about rooms that are too stuffy or too cold, the issue may be with the zone control. It’s also possible that the packaged rooftop unit has lost cooling/heating power (such as because of leaking refrigerant). Call for professionals to look into the uneven temperatures.
  • Appearance of water condensation in the workplace: This is an issue specific to a Miami summer. Because air conditioning helps to combat high humidity levels (when it absorbs heat from the air, it also absorbs moisture), when it starts to malfunction, humidity inside the building will rise. This will first show up as condensation along windows and other external surfaces. At the first sign of condensation problems, call for assistance from repair professionals.
  • Strange smells from the vents: Acrid or moldy/musty smells coming from the vents usually point to repair issues. The burning smells sometimes point toward motor and electrical problems inside the rooftop unit(s) that will need to have technicians replace the burnt out parts. Musty and moldy smells usually indicate that there are leaks and breaks along the ventilation system that will require sealing. Bring in commercial specialists to look over the system and determine where the issues are and then fix them.

Air on Demand takes pride in the skill of our team for providing quality HVAC services in Kendall, FL. When the comfort of your employees, customers, clients, and/or tenants is in jeopardy because of a malfunctioning HVAC system, make us your first call.

The Famous Painting of the Declaration of Independence Isn’t What You Think It Is

Friday, July 4th, 2014

If you grew up in the United States, you probably first saw John Trumbull’s painting of the Signing of the Declaration of Independence in an elementary schoolbook. This oil-on-canvas 12’ x 18’ painting hangs in the rotunda of the United States Capitol in Washington, D.C. It is one of the most famous symbols of freedom in the country and almost every citizen can conjure it from memory.

Except… the painting isn’t of the singing of the Declaration of Independence. The actual title of the work is Declaration of Independence, and although it does portray an important moment in the history of the document that announced the Thirteen Colonies’ decision to break away from British rule, the event in the painting occurred on June 28, 1776, not July 4, 1776.

John Trumbull, a Connecticut native who fought in the Revolutionary War and whose father was the state governor, was commissioned to create the painting in 1817. He did painstaking research on the figures in the picture and also visited Independence Hall to see the actual chamber where the Second Continental Congress met. Trumbull only included 42 of the original 56 signers, because he could not find adequate likenesses for 14 or them, and added a few figures who were not present (most of whom declined to sign the actual document). In fact, the men depicted in the painting had never been present in the same room at one time.

So if the painting does not portray the signing of the Declaration of Independence, what is happening in the image? The Trumbull’s scene depicts the presentation of the draft of the declaration to the Continental Congress for editing and approval. The five-man drafting committee (John Adams, Roger Sherman, Robert R. Livingston, Thomas Jefferson, and Benjamin Franklin) is handing over their finished work, which congress would then edit carefully over the next few days before voting on it and signing it on the day that we now celebrate as the start of the United States of America.

One last, odd, fact: two of the five-man drafting committee, John Adams and Thomas Jefferson, both died on July 4th—although many years later.

Our family at Air On Demand hopes that your Fourth of July (or Twenty-Eighth of June if you decided to start celebrating early) is a memorable and happy one.
