They were professional and on time.

Amazing. I requested a quote for a replacement of my entire HVAC system. When they determined they were so booked up that it would be a little bit before they could replace it, they asked if anyone had tried to repair it for me first (its very old, so the answer was no). They took the unit apart, figured out quickly it was a fuse and a capacitor that had blown, and repaired it for me. I tried to pay them, but they didn't accept. These guys are a class act, and they moved to the top of my list for all HVAC equipment-

Everything went per plan, price, and schedule and my high efficiency furnace is still working great. Technicians left the basement area, and the interior of my furnace, clean and neat. Technicians explained everything about the problem and repair in terms I understood. Technician actually called me first and arranged to arrive ahead of schedule.

It went VERY well. Duvall Corporation is family owned and two generations of the family, along with two other technicians, came to my house and worked for two days to do a SUPER job in tearing out the old mechanicals and putting in my new HVAC and water heater. These folks now have a customer for life in me. I give them my BEST review. Punctual, respectful, nice, know their business and products and are tidy, too! Thank you, Duvall Corporation!!

Went very well. They were on time every day and cleaned up at the end of each day. Friendly and curtious.

Did not show respect by not having or refusing to use shoe guards on light colored carpet. Two spots of dirt were left on the carpet as a result. Changed insides of toilets and they are much more quiet. Told me what to order to repair sink. Said the house water pressure valve was leaking. I agreed to have it replaced. At his urging he reduced the water pressure for the house. I hated the low pressure and the fact it would still cost $125 just to come out and fix the sink leak and having no cold water.

They are fantastic. They have always been fair and reasonably priced. Everything they've ever done has turned out well.

We called for emergency service on a weekend. The guys arrived faster than expected. The service tech was upfront about the costs of the emergency work. When they got to our house they found the problem quickly and made the repair. The price was less crazy than we thought and they were fast and smart about finding the source of the problem. I had used a different company for a previous problem and watched that guy stretch a less than one hour visit in to a 2.5 hour call. These guys didn't fool around. I'm very glad we called and our water was back on quickly.
