Ascendant Heating & Air Conditioning

We have been loyal customers of Ascendant Heating & Air Conditioning for many years. They have always provided top-notch furnace repair and maintenance services for our home. Over the years, we've had them replace our furnace, and they also handle our annual furnace inspections and cleaning to keep everything running smoothly—especially important with Colorado’s cold winters. Thanks to their expert recommendations, we even upgraded our system to help with humidity control due to our older home's unique needs. The team is honest and never pushes unnecessary repairs or upgrades. Herbert, who handles our appointments, is trustworthy and always looks out for our best interests. We truly appreciate the reliable service and care we receive, and wouldn't trust anyone else with our furnace repair

Ross, Brendan, and Matthew were very professional and efficient throughout the whole process. They explained everything clearly, including how to use the new thermostat, and made sure I understood how my heating system works. The crew was friendly, polite, and cleaned up after themselves before leaving. I was really impressed with their work and wouldn't hesitate to call them again for any furnace repair needs. Highly recommend!

Our old system stopped working in the middle of summer, so our house was getting uncomfortably warm. Ross came out right away to go over our options and helped us choose a new, high-efficiency HVAC system (97% efficiency, 16 SEER) that qualified for great rebates. Ross was very knowledgeable and professional throughout the process, and even brought over a portable AC to keep us comfortable until installation day. When it was time for the install, Herbert and Brendan arrived on schedule and got right to work. I tend to ask a lot of questions and like to watch the process, and they were very friendly and patient, explaining everything as they went along an

ross came out to check our heater after another company said we needed a full replacement. instead of just trying to sell us a new unit, he took the time to carefully inspect everything first. after a thorough look, he quickly found the exact part that was causing the problem and explained it clearly to us. he was able to get the part and came back to finish the heater repair just two days later. the price was fair, and the whole process felt honest and efficient. we really appreciated how easy it was to communicate, even getting a quick reply to our email on a sunday evening. we'll definitely use ascendant heating & air conditioning again whenever we need help with our heating in denver!
