Our company is a second- and third-generation, family-run business. We are all working together with a common goal of happiness and success for ourselves, family, and friends. With this goal in mind, we offer honest opinions regarding service and, if necessary, installation of new HVAC equipment. We are a member of the BBB with a great rating and have been doing this day in and day out since 1954. We do not believe that a system installed in your home that will last for years to come should be installed in a rushed manner. We custom make all duct work fittings for each unique HVAC system. We take pride in every aspect of our business from a simple service call to the most difficult installation. We have built our business on word of mouth, which is the best advertising in the world. Please give us a call!

"Wow! This company did an outstanding job. Our furnace was old and not working and Josh gave us a better price than the other companies and got it put in the next day. He kept in touch with me the whole time and the guys that installed the furnace and cleaned out the flue were great also. They even cleaned up afterwards. It all went very smoothly. We would definitely recommend Comfortable Carla's Heating and Cooling. Thanks so much for a great job well done!"

Heating and Air Conditioning questions, answered by experts

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

If you run an AC with a dirty filter, it could allow dust and dirt to build up in your ductwork, which could make you sick. At the same time, your air conditioner won’t work as efficiently as it would with a clean filter, likely resulting in less airflow, more wear and tear on your HVAC system, and higher energy bills.
