"We had a great experience with Cool R Us. Our first contact was with Josh, who arrived at our home on time and completely prepared. He was very personable and truly professional, and quickly put us at ease. He asked questions to see what our priorities were and explained what his recommendations were and what each particular HVAC unit would do for our home environment. There was no pressure to decide immediately and he quickly sent us an online quote for all of the units that he recommended for our needs. Once we decided, we were given a very fair price and the installation was set up to accommodate our schedule. The installation technicians let us know they were on their way. They arrived and worked quickly and efficiently to remove the old unit and install the new one. These gentlemen were also very personable and professional and obviously, very knowledgeable. When installation was done, they did a complete clean-up and left our home spotless. Adem helped us to set up our digital thermostat and explained how to use the thermostat, which was one of our major concerns. He assured us that an answer to any questions we had was only a quick phone call away. After our first day of using our new unit, the humidity level in our home dropped appreciably and the air felt so much cleaner. We are very pleased with our purchase and highly recommend Cool R Us."

"My AC went out in the middle of the Florida summer heat and Florida Air Conditioning had my system completely replaced in about 24 hours. They were professional, fair priced, and provided excellent customer service. I would highly recommend!"

"I had to have my complete HVAC system replaced and I hired David Gray. What a wonderful experience. The three gentlemen that did the installation, Gabe, Zahkeem, and Muhamed were so professional and courteous. They did a fantastic job and were very meticulous, making sure everything was perfect and once installed they made sure everything was cleaned up and they made sure I understood how to use the new thermostat. They should be highly commended on their work ethics and professionalism. Highly recommend David Gray."

Heating and Air Conditioning questions, answered by experts

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills.
