Longmont, CO Expert AC Repair Service

Air conditioners consist of a rather complex configuration of components all working together to provide effective cooling. A tiny refrigerant leak, buildup of dirt on coils, damaged fan blades, faulty thermostat and all sorts of issues can significantly impact performance. You might notice odd sounds or smells, higher running costs, warm air from vents or maybe the system fails to start up at all.

Whatever the problem, regardless of the brand of air conditioner, Welzig Heating and Air is the right call to make. Our NATE-certified, factory trained and extensively experienced technicians are proficient in residential and commercial cooling systems, covering everything from centralized air conditioners to heat pumps, ductless units, high-velocity systems and more.

Jim

Dave Kaplan-Gomez and James Miltersen installed my new Tankless Water Heater. Both were polite and professional. Care was taken not to damage anything in my house which I really appreciated. I use Welzig for all my HVAC needs and highly recommend them.

Chris

Bob came out to look at our swamp cooler and was remarkably helpful and professional. Not only did he give me a knowledgeable diagnosis, but he also taught me a lot in the process. We’ll be calling him for all future needs with our cooling system.

Clare

Our 23-year-old A/C system ran out of “borrowed time” and became too difficult to continue maintaining. With great advice from Casey Welzig,, we replaced the old system with a Bryant Evolution A/C system. Max Loustaunau and Seth Bernhardt did an excellent job with removing the old system and installing the new one. Both of them are great to work with — very professional and very personable. We are really amazed at how much better the new system works!
