"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

Yes, high-efficiency models reduce environmental impact with lower energy use.

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.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
