We first determine what size unit is appropriate for the home before making suggestions for the brand and model. When it comes to central air conditioning units, bigger is not always better, which is why we do a complete home assessment first to determine your home's specific needs.

Hely Heating and Cooling installed two air conditioning systems (ductless mini split and traditional split) into my all-brick, 90-year-old, two-story city house that had never had central air. They were very careful, and respectful of both my home and my anxieties about such a major project. The end result looks great, the price I paid was fair, and all communication regarding timeline and expectations was very good. I am greatly enjoying the added heat function of the ductless system upstairs and look forward to summer!

Mr. Arthur and Alex from Hely Heating & Air Conditioning did an excellent job with the installation of my new AC unit. They maintained a clean working environment and had a lot of patience as they assembled the unit. They spoke among each other professionally and respectfully. My new unit has a peaceful hum to it. The AC Compressor outside sounds like it can tackle some heavy-heat without any throttle. It is a clean and sharp-looking machine.

My installation of my air conditioning and heating was done in one day. The gentleman who was involved in the installation was very courteous, professional, and answered all of our questions. He gave a demonstration of everything and how it works and gave us his phone number in case we had any questions later on. He cleaned up everything and hauled the old unit away.
From the time I called until the installation was done was just a matter of a couple of days. The price was in our budget as well. So appreciative of this company. Would recommend it to anyone.

Amazing Service! They are great! Our AC went out after the 4th of July, and Tim came out that same day to repair our unit. He diagnosed the issue in less than 10 minutes, and had it fixed in less than 5. I am extremely grateful for their great service and quick resolution! I would highly recommend calling them!

Hely Heating & Air Conditioning, has always been thoroughly professional and consistent. I had them install an entire HVAC system in 2014, and have had a maintenance agreement with them since that time, so I see them at least twice a year. They are knowledgeable, competent, on time and reasonably priced. It is reassuring to know such an expensive investment in equipment is being well cared for at a reasonable price!
