Keller Heating and Cooling

Dallas Keller is the absolute best. He fixed a botched duct work job and installed a mini-split in my attic dormer at a very reasonable price. Very respectful, on time and extremely competent. Very nice to work with and I love my toasty upstairs now.

Dallas was absolutely AMAZING! I had problems with the HVAC people I originally hired who left the job unfinished and did terrible work but Dallas came to the rescue! He saw all of the things I was concerned with immediately! He put in new ductwork, moved my furnace, did the pvc piping, hooked up my thermostats, and more.! He is incredibly knowledgeable and talked me through everything he thought should be done very patiently and thoroughly so I understood. Dallas also kept me posted and sent me texts and pics of exactly what he was doing at every stage. He worked within my budget and did an incredible job. He was also very friendly and great to work with! I would give him a rating of a million stars!

Extremely satisfied. Dallas was thorough in diagnosing the issue and fixed the unit in a timely manner. He was also patient and answered all of my questions and gave tips on maintenance. Great rates , great service , trustworthy person, you will not go wrong with hiring Dallas Keller for you hvac needs.

Dallas is great! The only HVAC tech who was willing to take our furnace fan assembly out and thoroughly clean it. And no unnecessary upselling like the big HVAC companies. Highly recommend

Upfront with a diagnostic pricing that most don’t offer. He was honest and wanted to find the true problem, not hit me with a huge bill if he found a loose wire… I had a problem with my thermostat not getting power and therefore my HVAC was getting any signals either. Dallas responded right away, came same day! He found both a broken wire by the thermostat and also a transformer that had gone bad near the board that wasn’t putting out enough power to power the circuit board. So the fix ended up being a $20 part! I’ll use ONLY him for the future and recommend him to anyone who wants an honest and reliable HVAC professional!
