"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

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
