"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."

"Sam is excellent! He replaced two HVAC systems for me, took the time to talk through and price-out many different options, solved some problems along the way, and when an issue arose he stood by his service and made it right. Sam is a professional and I've already recommended to friends."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."

Heating and Air Conditioning questions, answered by experts

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

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.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
