Commercial HVAC and big units

Rooftop units, larger split systems, and big compressors for shops, offices, restaurants, churches and light industrial buildings.

Safety first. If you smell gas (a rotten egg smell) or hear hissing near a gas appliance, leave the building now. Do not use light switches, phones or anything that can spark inside. From a safe place, call 911 and your gas company (Enbridge Gas Utah emergency line: 1-800-767-1689). (Source: Enbridge Gas) If a carbon monoxide alarm sounds or people feel headache, dizziness, nausea or confusion, get everyone outside to fresh air and call 911. (Source: U.S. Centers for Disease Control and Prevention; U.S. Environmental Protection Agency) Do not try to repair gas, refrigerant or electrical parts yourself.

Refrigerate has HVAC-certified technicians and is building out its light commercial work. If you manage a building in Utah County or the Salt Lake area, send a request with the unit type, size (tons) if you know it, and the problem. Refrigerate reviews each commercial request and will tell you if it is a fit.

Key facts

Federal rules require anyone who adds or removes refrigerant, or attaches gauges to an AC or heat pump, to hold EPA Section 608 certification, and refrigerant for home AC and heat pumps can only be sold to certified technicians.

Utah licenses HVAC contractors under the H100 HVAC Contractor classification through the Division of Professional Licensing (DOPL). H100 qualifiers must be certified natural gas technicians (Rocky Mountain Gas Association or equivalent) and pass the H100 trade exam. You can look up any contractor license on the DOPL Licensee Lookup. (Source: Utah Division of Professional Licensing; Utah Division of Professional Licensing; Utah Division of Professional Licensing)
ENERGY STAR maintenance basics apply to commercial equipment too: clean coils, tight electrical connections, clear condensate drains and correct refrigerant charge. (Source: ENERGY STAR (U.S. EPA))

FAQ

Do you work on rooftop units?

Send a request with the unit details. Refrigerate reviews each commercial request and will say whether it is a fit.

Can this site tell me what is wrong with my furnace or AC?

No. Utah HVAC Help is general information, not a diagnosis. Gas, refrigerant and high-voltage electrical parts need a trained HVAC technician. If you smell gas or a CO alarm sounds, leave the building and call 911 and your gas company from outside.
