"Abel Air came to the rescue! Doug was a godsend for us on one of the coldest days of the winter. He replaced our boiler in a timely manner and did so within the quoted price he first gave us. There was some wrinkles and additional work he did not expect, but he did it all for the same price he initially quoted. Doug and his team are thorough, communicative and completely professional. I would recommend Abel Air for all your HVAC needs. Doug is also one of the nicest guys we have encountered to do work on our home."

See website for additional service area. Additional email - [email protected].

"Dreadful experience. We had been customers of Astacio since 2015 when they installed our first tankless boiler which failed completely after 7 years and needed to be replaced in late 2022. ($10,000+) Their second one just stopped working; a dodgy board? The part is under warranty but they want almost $1,000 to replace it in the boiler; probably less than 2 hours work. I thought they used to be a good local business with ties to the community but be careful; their tankless boilers are unreliable and they'll try to rip you off when your heat goes out in the winter. So much for standing by their work. I'll never use them again."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"After meeting with and getting quotes from other A/C contractors, we decided to work with Jason at JLS Mechanical. We had a great experience working with JLS Mechanical and would wholeheartedly recommend them without any reservations. Jason helped find a creative solution to fit AC into our very old (but charming) Tudor home. He gave us a realistic estimate and stuck to it (no upcharging). His team members are knowledgeable, courteous, showed up on time (and let us know in advance if they anticipated any delays) and their work was neat. JLS Mechanical was very professional and they took pride in their work - which is not always common these days."

We are a father-son owned HVAC business established in 1989. Our work stands out because of a few reasons. First, our attention to detail is of uttermost importance, not only aesthetically, but our heating/cooling calculations are double and triple checked. Secondly, we listen to our customer's needs and customize solutions based upon their specs and bottom line. By far, the best part of the job is getting to know our clientele!

Heating and Air Conditioning questions, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable
