"Peter did an excellent job tuning up my A/C system. He was extremely diligent in making sure my A/C unit was up to speed for cooling for the upcoming summer weather. I know I will most likely need a new system installed in the near future as this one is on it's last legs. I know who to call when I need a new A/C unit installed and it will be Peter!"

"Excellent. I've had Genove install both gas and oil heating systems in my properties, most recently oil. They have also installed central air/hydro air and handle my oil delivery. The techs have always been polite & knowledgable. Their customer service is impeccable. As a landlord/home owner, I couldn't be happier with them handling all my HVAC needs and would recommend them to anyone."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"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."

"Ken's HVAC was immediately responsive to my call and came the next day. When we noticed an additional heating issue I called on Sunday and Ken picked up and scheduled to come out on Monday. He did, and we now have heat. Ken was thorough, professional, and explained everything he was doing. I felt very confident in his work."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"Our oil burner cracked and needed to be replaced. The burner heats our water, so we would be without hot water until we replaced the burner. Steve Chamber arrived quickly, provided a competitive quote and got the oil burner installed and our hot water restored within a few days.. The final bill was exactly what was quoted and they cleaned up after themselves, even removing the cardboard boxes. I highly recommend Chamber HVAC and love that it is a family owned and operated business!"

Heating and Air Conditioning questions, answered by experts

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

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.
