"I was having some problems with an oil furnace heating system and another problem with excessive heat on the second floor during the summer. Ryan did a thorough analysis of the heating and cooling needs of my home and noted the challenges of getting good coverage with the way my home is laid out.  Ryan recommended a heat pump, a zoning system, some vent modifications, and a separate mini split system for the home office addition. The project was a ton of work, and Ryan did a great job with the install of the high efficiency main house heat pump and a Honeywell zoning system, a whole house air purifier, and a mini split heat pump system for the addition. He also removed the old oil tank and A/C unit, patched any access spots, and cleaned up the area.  The new system is much more comfortable and way more efficient than the oil furnace and A/C unit that we used to have.  It has definitely saved us A LOT of money, especially in oil and energy prices right now.  Ryan was extremely responsive via email and phone, was always super professional and kind, and I truly believe he wants to do what's best for the customer! 100% would recommend Ryan to anyone needing HVAC work done.

"Ryan is my go-to guy for not only HVAC projects, but also everything else related to home improvement and repair.  Ryan has done multiple installs and repairs for me, and many times, when it was very inconvenient for him. He is always very eager and ready to explain his plan in a way anyone can understand and be confident in. Ryan's level of expertise and personability is one that is uncommon in any trade, and his ability to quickly overcome unexpected and unforeseen obstacles is quite impressive. In every project he has completed for me, he has exceeded my expectations every step of the way. You will be doing yourself a huge favor allowing Ryan to service your needs!" -Bill and Jess R.

"We highly recommend Ryan and Keller HVAC. He was referred to us by our neighbors to install our new A/C unit. He is incredibly knowledgeable, professional, and efficient. He fixed an issue we were having from our furnace as well and found things taht were done incorrectly by Bovard when they installed our furnace a few years ago, and he fixed them for us! He cares about his clients and went above and beyond what we could have asked for. Thanks so much Ryan!" -Jordan S. 

"Ryan does great work and is very accommodating to make sure we were happy with the end product. We had two mini split systems installed for AC/Heat. The placement of the lines was well thought out to ensure it produced the least amount of outside and inside lines, producing a very clean look. He is very detailed and neat, making sure not to leave behind any messes for you to clean up. Highly recommended!!!" -Tyson and Terri R. 

"I was having issues with my boiler tripping out on safety. I had contacted Ryan and explained what was happening. Ryan diagnosed the issue and actually went the extra mile to make sure my boiler was running more efficient than it has been in the past. My work has me out of town, and Ryan kept me posted all the way so I knew exactly what was going on. I would highly recommend Ryan for any of your service needs." -Andy and Faith P.

"Keller HVAC responded almost immediately after regular working hours to my A/C not cooling the house during a very hot period during the summer. Ryan methodically and professionally diagnosed the problem. He ordered the part, however due to COVID, logistics wouldn't allow the part needed to get here as quickly, therefore Ryan contacted another supplier for better service. It came in a few days. After installation, there was other collateral damage from refrigerant spraying onto electrical components inside the air handler. Even though the unit supplies warnings and codes, the root cause is not always easy to find with electrical components. Ryan methodically and patiently worked through these problems because there were multiple issues. Working thoughtfully and meticulously, he found the root cause and repaired it. I would highly recommend Keller HVAC. Very knowledgeable, methodical, personable, reasonably priced, great work ethic and quality workmanship." -Mike G.

"Ryan does AWESOME work. I told him what my needs were and he recommended the perfect system.  It works WAY better than I anticipated. Ryan will not steer you wrong. I will use him for all my HVAC needs!" -Andy H. 

 "I would like to give a strong recommendation for Keller HVAC. I have known Ryan and his level of expertise in HVAC work for several years. Ryan is thorough, fair and efficient in his ability to analyze a situation and determine a solution. Keller HVAC will be my go to HVAC company. He is reliable, honest and a great man to work with for sure."  -Duane C. 

"Top notch quality, installation, and service. I have had three local HVAC companies service our home in the past, but not until Ryan Keller installed a new high efficiency gas furnace and new central air system in our home was I completely satisfied. The quality of his work is exceptional. No solder joint runs or leaks. He does very neat work, cleans up when his work is done, and doesn't charge an exorbitant fee.  Additionally, he is very personable and takes the time to fully explain his recommendations and other possible options.  Just a pleasure to speak to, and just top notch service. I highly recommend Keller HVAC. Ryan is my choice for all our heating, ventilation, cooling and plumbing needs." -William R. 

"We were really pleased with the work that Keller HVAC did on our heating system.  Not only was he prompt at ordering the materials but also prompt at getting the system installed.  The customer service was great.  He answers all your questions and makes sure you are fully satisfied with the product.  We would definitely recommend him to all our family and friends." -Mark and Emily B. 

"My air conditioning stopped working on a 90 degree day. Ryan came quickly and had my air conditioning fixed and blowing cold air before I knew it.  He is very dependable, knowledgeable and does high quality work.  I would highly recommend his services to anyone." -Amanda A.
