"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."

"I've used this company for a few years, beginning with an issue I had where I needed some emergency assistance with an a/c system leaking water into the house. They fixed the issue and it cost far less than I thought it would. I've also used them for a couple heating repairs, annual furnace cleaning and a/c maintenance. I am about to hire them again since the a/c system is dying and it will need replacement since it's more than 20 years old. I would highly recommend Unique Indoor Comfort to anyone in need of a good HVAC/Heating company."

"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

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.
