HVAC reviews in Glenwood, Maryland

This is a great company very honest people and trustworthy.

I’ve used ASC a total of three times now. One of which was a total system replacement. Quality service, great prices, and good people.

Mark has been wonderful and I recommend him to all my family and friends. Very reliable and we have been using him for over 30 years.

Excellent service. Called them after hours and they came the following morning (Saturday) to look at our unit. Wonderful people and truly customer service. Highly recommend!

Extremely unprofessional and unreliable. Don't waste your time/money with these guys. They set an appointment for a Friday afternoon and didn't call when they missed the scheduled time, so I call them to check on the status. They said they were running a little late, but would be there. A half hour later, I called back to see where they were and was told it would be at least another hour, maybe more. I said that I couldn't keep waiting that long because I had a conflicting appointment...They said they could come on Saturday, but I'd have to pay the emergency service fee. I told them that I'd prefer to just reschedule for Monday. On Monday, they did not show up at the scheduled time and did not call, so I called them repeatedly until I got through (30 minutes later...). I asked where they were and they said they were 10 minutes away. 30 minutes later I called back because they still had not arrived and the driver/service guy (Mark) said he was 10 minutes away...I said that that was what he had told me 30 minutes ago and that I needed an honest answer because I am missing work for this...He said he didn't need my attitude and wasn't coming, then hung up...I was speechless. This clearly isn't a serious business and frankly I'm glad he never came because who knows how much damage he would have done working on my HVAC system.

Woke up on a Sunday morning and furnace was not working. Service call guy explains control card and igniter needs to be replaced on 23 yr old unit. We go with furnace replacement. Of course that service provider was hoping for a spot (pressured) decision that was $2500 more than we paid). Do your homework folks! Frantically start calling around and touch base with friend of the family that recommends ASC. Called Mark (owner) and he came over first thing Monday morning. I also got three other estimates. Mark was most straight up, straight forward, did not over sell, kept it simple, convinced us to do AC at same time and save $1500 from doing it later when it craps out (also 23 yrs old). We had a few decisions to make – he kept them easy and again didn’t over-sell performance/savings when other providers obviously did. ASC provided lowest price. The install was the next day, seamless, did some extra vent work (no charge) to align furnace in better space in furnace room. Call Mark – get a quote – top shelf.

Danny saved us on a 90+ degree day when of course our AC stopped. Not only did he solve our problem but checked the unit to make sure that was the only problem. We were going out of town a couple days later and we wouldn't have gone if the problem hadn't been solved. Really appreciate the service and professional manner. He wore a mask despite the heat.

Dan was here within 30 minutes from when I called, and fixed my heat pump in less than 30 minutes. It was just a bad fuse, so I got lucky there. Very friendly, professional and a fast response with a pending blizzard a day away. I highly recommend!

We have used them for years and never had a bad experience. Their prices are much more reasonable than the bigger guys. Not sure why anyone would rate them lower than 5. I’ve had a system completely replaced and they were professional and MUCH less than the other bids I got.

After this 100° temperature marathon, we have in Maryland our air conditioner flooded our house.
We have an old house so we have used many plumbers and HVAC services . We called Mark and he sent out the one of his teammates Ryan the next day. We are so grateful! Diagnosed and fixed the problem in less than 40 min. We would recommend this company hands down!!!

We have started to use Mark within the last year and he has very quickly become our go to guy for our clients for any HVAC needs, including our own home. We would recommend him and his crew to anyone!
