"This company was great! Very different experience from the last AC company I used. The technician was communicative and personable. He took his time going through my entire system and explained all of his recommendations to me for improving my comfort and system reliability."

"It was absolutely amazing to work with E Z air conditioning. He was on time to the appointment and was very clear about what work needed to be done and how much it would cost. When it came to pricing, he was willing to present all the details to me with such clarity that I didn’t feel like he was hiding anything. His candid way of communicating makes you feel like you’re just chatting with a normal person and not a slimy sales guy. The work took about 2 hours and it was worth every penny. Peace of mind and quality work. Thank you E Z Air!!!"

"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."

"After having another company tell me it was a Reverse Valve issue and pretty much said "good luck" as he left, I called Fenwick/Weychoff and they had a tech out by 9pm same day. The tech, Mark Wesley, not only fixed a simple issue and got my house cool that same day, but only charged me the base price for the service call. It ended up being an issue with the thermostat. Nothing wrong with the reverse valve. Thanks, Mark, and thanks, Angi, for recommending Fenwick/Weychoff! Respectful and honest. They've got my business from now on!"

Heating and Air Conditioning questions, answered by experts

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
