Heating & Air Conditioning / HVAC near Rockville

“Many companies claim to offer great service, but David L Hall Heating and Air Conditioning truly delivers. Jacob Beck, the last technician who helped us, spent several hours tracking down a tricky, on-and-off problem. He got our system working again and made sure we were happy with everything. If you’re thinking about getting a new HVAC system for your home, or you just need service, I recommend talking to them. They listen, they’re honest, they absolutely care about their customers, and their prices are fair. Choosing David L Hall Heating and Air Conditioning was the best decision we made for our HVAC needs.“

“Sergei is the best. He is knowledgeable, efficient and gives fair prices. Thank you!!! Now off to do laundry.“

“These folks are the best! They installed a new boiler for me a few years ago and I've been thoroughly pleased. This week I thought I had a gas leak and they came right out. As it turned out I had a plumbing problem. Not only did they resolve the plumbing issue but took the time to do a routine cleaning and maintenance on my boiler. I would absolutely recommend Hudson 1000%. Furthermore, they are trustworthy which goes a long way in my book!“

“Freezone was great to work with! I submitted a non emergency service request at 11pm and received a call by 9:15 the next morning to confirm my appointment for that afternoon. My tech (Chris) had a cancellation in the morning and was able to arrive by 10:30. Within 15 minutes he had diagnosed and replaced the faulty capacitor. So my A/C was back up and running within 12 hours of submitting a service request. Additionally, the pricing was very fair and all of my interactions with the company were very professional. Overall, I am very pleased with Freezone’s promptness, competitive pricing, and professionalism. I would definitely recommend them.“

“I worked with Bobby adams back in 86-87, We would rough-in 5 houses a day with a long lunch. We could set the condensers on half a subdivision without stopping. I'd get my butt back to Farmville for some sleep and then back at it. All the work I witnessed him perform was quality and the effort he put in for his father, i'm sure it still is. I would recommend all day, across the board.“
