"We are so pleased that we used Joe and AIR EEZ. He responded within minutes of my inquiry and was able to come out and service our central air conditioner within 24 hours. Other vendors we called said they could not get to us for a week. With the temp and humidity so high, we could not wait that long. Joe was fantastic! Knowledgeable, prompt, honest, and very reasonable. We will definitely use Joe again for any future HVAC service needs. Thank you so much!"

"The man who came to my house to describe the furnaces and help determine which one I wanted could not have been more wonderful. He was helpful and efficient. We had agreed on a week when the work would be done. The installers called and wanted to come a week earlier. I okayed it, but it wasn't the best day for me. They were nice and efficient. The new furnace appears to be exactly what I wanted. However, the new thermostat control was a different size and shape from the original one and they didn't patch the holes or repaint the edges--not a big deal but when I got a security system a few weeks ago, they did do all that finishing."

Heating and Air Conditioning questions, answered by experts

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

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.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.
