"Mike installed a new heating and ac system to replace my old system. His preferred brand availability and choices were clearly explained. His work was completed quickly and clean up was great. He was able to beat all other quotes for pricing and labor. He took extra time to double check the system. He also balanced out the air distribution inside in order to better cool a traditionally warmer area of the house. I would highly recommend him for any HVAC service."

"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

"I hired Best Air Quality and Restoration to clean my dryer vent. I was very pleased with their level of professionalism. All my questions were answered without hesitation. The price was fair and affordable. Dennis, the technician notified me of his expected arrival time. He was very nice and pleasant. Dennis explained what the job entailed and completed the job within an hour. There was no excess lint or debris in my home to clean. I would recommend Best Air Quality and Restoration to others to experience for themselves. I intend to use other Best Air Quality and Restoration services again in the near future."

Heating and Air Conditioning FAQs, answered by experts

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

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.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
