HVAC maintenance in St. George

Book service before the season, not during it
Cooling service is worth having done in spring, before the first sustained hot stretch and before every contractor in the county is booked solid on emergency calls. Heating service belongs in autumn, before the first cold night finds the problem for you.
The scheduling reason is as good as the technical one. A system checked in March gets an unhurried visit. The same system failing in July competes with everyone else's failure, and you take whatever slot exists.
What you can do, and what needs a license
Yours
- Check the filter monthly through the cooling season and change it on condition rather than on the calendar. Follow your equipment manufacturer's guidance for the specific system.
- Keep plants, fencing and stored items back from the outdoor unit so it can breathe.
- Rinse loose surface dust off the outdoor coil fins with a gentle hose — power off at the disconnect first, and never a pressure washer, which folds the fins flat and makes the problem permanent.
- Keep supply and return vents clear of furniture and rugs.
- Watch the condensate drain for standing water.
Theirs
- Refrigerant charge measurement and any refrigerant handling — a licensed and EPA-certified job, and the single most commonly botched item in the trade.
- Deep coil cleaning, indoor and out.
- Electrical testing: capacitors, contactors, amp draw against nameplate.
- Blower and duct static pressure checks.
- On the heating side, combustion analysis, heat exchanger inspection and venting.
Beware of anyone who "tops off" refrigerant annually without finding a leak. A sealed system does not consume refrigerant. If it needs more every year, it has a leak, and adding gas to it is selling you the same problem repeatedly.
