"I purchased a new HVAC system from Delta Heating and Cooling almost two years ago. The last few days my AC wasn’t working as well as it should. I called Delta in the morning and got a quick response. Garrett from Delta HVAC was at my house in a few hours. He spent a lot of time thoroughly checking things out, found the problem and made some adjustments and solved the cooling issue. Great job! I definitely recommend Delta Heating and Cooling!"

"Delta T was fantastic! I called them about an AC issue, and they were able to get a technician out to our house the same day. He took his time to thoroughly inspect the system instead of rushing through it. He clearly explained what was going on, let us know that a full replacement might eventually be needed, but reassured us that it wasn’t urgent. It was a huge relief to get honest, straightforward advice without any high-pressure sales tactics. The staff was genuinely helpful and friendly from start to finish. On top of that, the technician lives just down the road. It’s refreshing to work with a local company that truly cares about the community and stands behind their service. We’ll definitely be calling Delta T again for any future HVAC needs."

"Mike Jeanneret come out after 4 years of off and on struggles and I was sick and tired of using big name companies that left me high and dry. He was the only person from the 5 total companies I’ve hired over 4 years to check my entire system and give me all the options and information without trying to sell me anything. Price wise they were great and Mike was a great professional who didn’t try to sell me a hunch of horse manure I didn’t need. I had an idea of what was wrong he listened to me respectfully and went to work handling business. Stop hiring the bob Hamilton , AB Mays and all these corps and hire Delta family men who care about what they do"

"During an extreme heat advisory, our air conditioning went out on a Sunday. We weren’t sure we’d be able to find anyone willing to come out so quickly, but DeltaT exceeded every expectation. Our technician arrived promptly, was knowledgeable, professional, polite, and worked efficiently to get our AC back up and running as quickly as possible. He took the time to explain the issue, answered all of our questions, and never made us feel rushed. In a time when dependable customer service can be hard to find, DeltaT truly went above and beyond. Their commitment to their customers, even on a Sunday during dangerous heat, speaks volumes about the kind of company they are. We are incredibly grateful for their outstanding service and will absolutely use Delta T for all of our HVAC needs in the future. Highly recommend!"
