The staff handled a thermostat replacement when my old unit started drifting. They recommended a model that fit my system and installed it quickly. The setup was straightforward, and they helped connect it to my phone. The temperature readings are more consistent now, and scheduling is easier. They also checked basic system operation after the install to make sure nothing else was off. Overall, it was a simple job done cleanly with clear communication.

I had a full system replacement done through Air Conditioning Champ after my old furnace and AC reached the end of service life. They walked me through sizing, SEER ratings, and duct compatibility in a way that made sense. The installation took a full day, and they kept the work area tidy. The new heat pump system is quieter, and the airflow feels more balanced. They also set up the smart thermostat and showed me basic programming. Permits and paperwork were handled without me chasing anything. It was a big job, but the process felt controlled and predictable, and the results have been consistent through changing weather over the past month.

They came out for an AC repair when the unit started blowing warm air during the afternoon peak. The staff ran diagnostics, checked refrigerant levels, and found a small leak near a fitting. They handled the repair cleanly and recharged the system, then stayed to confirm the temperature drop across the coil. nothing felt rushed, and they answered a few questions about filter changes and airflow. The system has been stable for a few weeks now, and cooling feels more even across the house. I appreciated that they didn't upsell a new unit and instead focused on fixing the current one properly. Scheduling was simple, and the arrival window was accurate, which made planning my day easier.

Air Conditioning Champ handled our replacement project with a level of care that felt top-tier. From the first visit, the tech explained options clearly, provided a precise estimate, and answered every question without rushing. Installation day ran on schedule, the crew coordinated like they do this every day, and they protected floors and doorways throughout. Startup testing was thorough, including thermostat setup, airflow checks, and a long enough run time to confirm stability. The cleanup was spotless, and the final walk-through covered operation, maintenance, and what to expect in different seasons. The whole process felt dependable and well planned, and the comfort improvement was noticeable immediately.

They came out for routine maintenance and made the appointment easy from the first call. The technicians arrived within the stated window, reviewed the checklist with me, and then got to work efficiently. They inspected the coil, confirmed proper drainage, and verified the system was cycling as expected. I liked that they explained what they were doing in simple terms without talking down to me. The visit ended with a quick test run and a clear summary of what looked good. I also noticed the area around the unit was cleaner after they left, which says a lot. The follow-up receipt and notes were organized and helpful for keeping track of service history.
