"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"Duct Kings came out quickly and spent one day thoroughly cleaning the vents and scheduled the aero-seal for another day. During the process they noticed an issue with their software and rather than ignoring it and continuing the work, they stopped and rescheduled to come back and finish when the equipment was working properly. They were thorough, respectful of my home (and my pets), and wonderful to work with. I highly recommend Duct Kings!!"

Heating and Air Conditioning questions, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

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.  

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

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
