AC Installation
Our AC installation services ensure optimal cooling performance for residential properties. Using factory-authorized Trane components, we replace outdated systems with energy-efficient units that reduce operating costs. Our technicians perform precise heat load calculations to determine proper system sizing, preventing common issues like short cycling and inadequate dehumidification. Every installation includes comprehensive system testing and customer education on operation and maintenance.
Heat Pump Repair
We provide expert heat pump repair services for both heating and cooling modes. Our certified technicians diagnose and fix refrigerant leaks, compressor failures, and thermostat malfunctions using specialized tools and genuine replacement parts. Emergency repair services are available 24/7 to restore system functionality quickly. We also offer maintenance plans to extend equipment lifespan and maintain manufacturer warranties.

Our ductless mini-split solutions offer zoned temperature control for homes without existing ductwork. These systems allow independent temperature settings in different rooms, improving energy efficiency and comfort.

We've used Stephen K Denny for years for all our HVAC and pool heater needs and have always been extremely happy with them. We recently bought a house to re-sell to our daughter and it turned out to be a total renovation. Stephen K Denny exceeded every expectation when it came to quality of workmanship, price, and professionalism on the job. Would not hesitate to give them the highest recommendation and will have no qualms about referring to our friends.

Drew Smith from S.K. Denny, responded immediately to our request and repair our A.C. Drew was thorough and was able to circumvent the issue until the back order part arrives. Thank you Drew!

I had scheduled Stephen K. Denny to do some preventative maintenance on our A/C unit. The maintenance crew did a great job! They cleaned the coils, checked for the ducts for leaks, replaced the filter and cleaned the blower fan blades! They were on time, very quick and left everything all nice and clean they way they found it. Way to go Logan & David!

It was time to get a new ac rather than try to repair my old one again. I had Stephen k Denny come out and was pleased with their pricing. My technicians were fantastic. They were polite and thorough and super friendly. My new ac is so much quieter than my old one and keeps my house humidity free. I never get those moments where I feel hot either. It keeps my house at a steady cool temperature. One of the best and most surprising things is that my electric bill has dropped! Fantastic service. Fantastic ac unit. Fantastic lower electric bill. I couldn't be any happier.
