Recommended Customer Reviews

HASCO installed our A/C unit in 2015 and has been servicing it since then. We had an issue with the unit recently that proved to be a difficult task. Cynthia was great and made scheduling easy. Lucas did an excellent job diagnosing the problem and he and Josh got our A/C unit fixed and running correctly. Thank you Sal for your persistence and always treating us so well. We have family ties with the company, but they have always done a great job for us and friends we have referred to them over the years! Thank you HASCO!

Not an honest repairman. If you want to be ripped off call him. We called him because our ac was blowing warm air. He acts like the most caring humble hard working man but he ripped us off. He so called repaired our HVAC and we paid over $1700 only to learn from a new repairman that Hasco should have looked for and repaired a refrigerant leak. I now have another expensive repair thanks to this man that did not care enough to do an honest job.
I must mention he made 2 trips. First trip he claimed it was a broken part of AC system. Cold air lasted less than 24 hours. Called him back and second visit he claimed 2 more parts And refrigerant needed. Btw the tech was the owner Hasch.

Called for an ac repair. I reported to the tech that I thought my refrigerant had run out. He never checks for a leak and does not ever look at the evaporator. He claimed my problem was a capacitor. He also recommended changing other parts that were not broken but old as well as a cleaning. $ 1200 later when he's done, the ac still didn't work. Then he put refrigerant in it and everything works. He then tells me I have a leak which is what I suggested in the first place. A month later and it's not working again. Two techs from different companies come over and check the evaporator first and immediately determine the leak is in the coil. It was apparent then and now that I was lied to and fraudulently diagnosed. I trusted this tech as im not qualified to know better.
I would stay far away from this company. Completely took advantage of me. And no they never called to schedule the leak detection after he determined I had a leak.

Highly recommend! Roy helped us with a leaky water heater. He was thorough, friendly and informative. He let us know exactly what the problem was and what the plan was to fix it. Thanks again Roy for your hard work and for being so friendly.

Hasco Heating Air-conditioning Service was great. Sal Jr. And his helper Mike did a great job installing a new tankless water heater. They are fast and clean also polite and respectful. I would highly recommend this company to anyone looking for plumbing or HVAC work needed.

I had Dan from Hasco out today for a no heat call.

I will use Hasco for all my Air Conditioning and Heating needs, definitely a company you can trust.
Thanks guys your the best

I had a last minute issue I needed handled in a few hours due to the fact that I was starting work for a new company last week. Start date was yesterday, Friday. So it had to be done Thursday. How would that look if I could not make it on my first day? BAD!!! I reached out to the People/Company I knew had the best chance of coming through for myself and family,neighbors,and friends. They have done so many times in the past. This was truly GO TIME!!!. I reach out to Sal,Chris and the HASCO Dream Team. He, got back to me and stated ""I'll have MY Guys there By 5pm"". They showed up not later than 4:45pm. This was a difficult task because my home is a split level residence and having to move heavy objects is no easy task. Needless to say...Mission Accomplished and I had a awesome first day at work, not feeling stressed about the things I needed done at my house. HASCO. Guys I cannot express enough of my gratitude, and gratefulness. For HVAC work and Much,Much More... Call The Hasco Team. Since 1983

We had an internal leak within our water heater, and it needed to be replaced immediately.
Fortunately the water heater was under warranty.
My husband contacted HASCO, spoke to Lisa who was very helpful and made sure to constantly following up to keep us updated.
Lucas the technician was very professional and explained the entire process start to finish. He completed the job very quickly and at a very reasonable price.
They even took care of the warranty process for us!!
Thank you Lucas, Lisa and all of the HASCO staff!
We will definitely call you for any of our heating, ac, or plumbing needs and will definitely be referring our friends and family!!!!

My AC went out on one of the hottest days of the summer. Called HASCO and even though they were booked up for the 3 weeks they came out the same day. They replaced my old un-efficient AC unit and put in a new efficient system that I can control from my phone.
