"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."

"This company came highly recommended, as many of today's technicians cannot service traditional "steam" boiler systems. Ever since last year's "furnace emergency", this "Old House" here found "its rescue match" with Pohlman Plumbing & CJ, a highly skilled specialist, who tweaked the boiler back to "steam". Explaining why my Amish-built "Oldie-Goldie" was here to last, CJ enjoyed "challenges" & was not trying to "up-sell". This positive experience of transparency & trust convinced us that we'd found "the" company for all our "Old House" future HVAC & plumbing needs, thx!"

"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 questions, answered by experts

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

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.
