"We had a Maynor tech (Gary) inspect our dual zone system yesterday and all went well. We called Maynor based on the multitude of positive reviews found on line. Our HVAC system had not had an inspection in 6 years and we knew we were overdue. Gary was very professional in his approach and very willing to explain what he was doing step by step. He found indications of mold on the coils and recommended the installation of UV fixtures to alleviate further problems. There was no pressure and instead shared photos off of his phone showing similar situations and the affect of the UV lights. Gary was able to provide and install the fixtures while he did the system inspection. We were very pleased with the manner in which this young man conducted himself and his working knowledge of the HVAC units. We're happy that we selected Maynor and look forward to a long relationship with them."

Heating and Air Conditioning FAQs, answered by experts

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
