Awesome company fixed my AC unit for a fair price when every other company was trying to galge me.

— James Deviers, Virginia Beach

Simply the BEST!

— Heidi Field, Virginia Beach

It has been about 6 months since the guys from DeltaT fixed my Trane heat pump/air conditioner. It has been working better than ever. They know what they are doing and they are honest. Before I had it fixed by DeltaT, another local company, their radio commercials feature an idiot, I spent thousands and it still wasn’t fixed right. I’m glad DeltaT fixed it right.

— Joseph Belmont, Virginia Beach

I was extremely pleased with the service and new system that they installed. Dave from Delta-T was professional, honest, and on time with everything. He answered all of my questions, no matter how dumb they were, and was straight-forward on the issues he encountered. Not to mention, the price was extremely competitive. I plan to utilize them for all of my HVAC needs going forward. I highly recommend Delta-T!

— John Bennett, Virginia Beach

Just cant say enough how great and professional these guys were!!I know companies are busy now with these temperatures and are swamped.Yet Dave made sure to get to me and get our heat back on going the extra mile!!I highly recommend Delta T for their fast professional attitudes and reasonable pricing!!My go to HVAC company!!!Thank you so much again!!

— Todd Gudac, Chesapeake

I could not be happier with the HVAC system installed by Delta-T Mechanical. David Connelly recommended a system that provided the highest level of efficiency for my budget. The system has performed impeccably and I have been extremely satisfied. I replaced two twenty year old systems and i can’t believe the difference in the comfort of the home and the reduction of my energy bills. The install was first class and very professional. After installing the equipment in the summer, Delta T came back as winter approached to start up the furnace and to make sure it was working perfectly. David also recommended wi-fi enabled thermostats that I am very pleased with. I would highly recommend Delta-T as a highly capable, professional and cost competitive contractor.

Delta T Mechanical is the only company who I allow to service/maintain my heating/cooling unit!  Very professional and honest!!

— Ladonna Phelps, Portsmouth

Delta T were incredible professional and I can’t praise these men enough. they saved me around 1000.00 dollars in comparison to 2 other companies quotes where I felt they were looking for ways to jack the price up. Delta T came in evaluated my entire HVAC system and gave me a very fair price and no hidden or additional charges, and the system looks and performs outstanding. thank you so much to Dave and his crew, God bless you.

“Delta-T saved us from having to buy a new furnace as a result of a previous contractor not having the technical knowledge to repair the leak. They went the extra mile in terms of workmanship and customer service to get the furnace up and running. It was a pleasure to work with Dave and Todd and we highly recommend them.”
