I went through this last season, and I can honestly recommend www.rmhvacutah.com . Their team came out quickly, diagnosed the issue right away, and handled the repair without trying to upsell me on things I didn’t need. The system has been running perfectly ever since, and I was impressed with both the professionalism and the fair pricing. If you’re looking for solid, trustworthy work on heating repair in Salt Lake City, I’d definitely say give them a call. I’m really happy with the result.
