What Makes HVAC in Murray Different

The Altitude Problem Most Install Crews Skip

Furnaces and AC condensers are designed and tested at sea level. Murray sits between 4,250 and 4,400 feet, depending on where you are in the city. Cottonwood Heights climbs to 4,800. At elevation, the air is thinner - which means a furnace burning the same amount of gas as it would in San Diego is burning too hot for the air it has, and a condenser pulling the same amperage is working harder than its rating allows.

The fix is called a high-altitude derate. On a furnace, that's reducing manifold gas pressure so the burner runs at the right BTU output for the air available. On an AC system, that's sizing the equipment with altitude-corrected load calcs instead of factory ratings. Most factory-shipped equipment includes a conversion kit for this, but it has to be installed and verified with a combustion analyzer. Skip that step and you're looking at premature heat exchanger cracks (5–8 years instead of 15–20), shortened compressor life, and higher gas bills the whole time.

The Murray City Power Rebate Gap

Murray is a little different. The city has run its own electric company since 1913, called Murray City Power, and about 18,000 homes inside the city get power straight from the city. The rest of Murray is on Rocky Mountain Power - mostly east-side homes, and homes that were added to the city later. There is no map you can look up by address. The only way to know for sure is to check the name on your electric bill, or call Murray City Utility Billing at (801) 264-2626. We ask this on every quote call.

Why it matters: the rebates you can get on a new heat pump or furnace are very different depending on the answer. Murray City Power has no home heat pump or furnace rebates at all. Rocky Mountain Power Wattsmart pays up to $1,600 on an air-source heat pump, $1,700 on a ductless, $1,450 on dual-fuel, or $2,000 on geothermal. Enbridge Gas ThermWise (the company used to be called Dominion Energy) adds $300 to $1,200 on the gas side, no matter which electric company you have - but only on furnaces and dual-fuel systems, never on a heat pump by itself. The federal Section 25C tax credit ended on December 31, 2025 and is gone for 2026 installs.

Winter Inversions and Your Indoor Air

The Salt Lake Valley sits in a bowl. In winter, cold air settles at the valley floor under a warmer layer above, and small bits of pollution (called PM2.5 - the tiny particles small enough to get deep into your lungs) get trapped close to the ground. The Utah Department of Environmental Quality describes it this way: “a typical Utah winter sees about five to six multi-day inversion episodes and on average, 18 days with high PM2.5 levels exceeding the National Ambient Air Quality Standard” (NAAQS - the federal pollution limit). Every time your furnace pulls in air from the house on one of those days, it's pulling that air through your filter. The cheap fiberglass filter most older Murray furnaces use (rated MERV-4, where MERV is a 1-16 scale of how well a filter catches small particles - higher is better) catches almost none of it.

Some good news on the bigger picture: on November 19, 2025, the EPA officially declared the Salt Lake City and Provo area to be meeting the federal limit for PM2.5 - for the first time in 15 years. State data shows valley PM2.5 dropped about 53% from 2001 to 2025, even as Utah's population grew 52%. The air is getting cleaner. But inversions still happen 5-6 times a winter, and on bad-air days, your HVAC is the first line of defense for everyone inside the house.

The right filter upgrade for Murray homes is usually a MERV 11 or MERV 13 filter. But you can't just slide a thicker filter into a 1-inch slot - it chokes airflow and trips the furnace's safety shutoff. The proper fix is a 4- or 5-inch filter box on the return duct, which gives the thicker filter enough room to breathe. We quote that upgrade as its own line item - we do not bundle it into something you didn't ask for.

Hard Water and Boilers in the East Bench

Salt Lake County water averages 13 grains per gallon of dissolved minerals - “very hard.” In Holladay's Olympus Cove and parts of Cottonwood Heights, it runs higher. Those minerals scale up inside boilers and tankless water heaters fast - sometimes voiding a warranty inside 24 months.

We price descaling service into our install quotes up front. Tankless heaters need a flush every 12 months in soft-water zones, every 6 months in the hardest pockets. Boilers need annual service that includes a heat-exchanger flush. If your installer skipped that conversation, you'll find out the hard way when the unit short-cycles 14 months in.

Old Murray Homes and Combustion Safety

Old Murray, parts of Vine Street, and a chunk of the houses near State Street were built before 1950. A lot of these homes still vent through original chimney flues that were sized for coal furnaces and later converted to gas, or shared chimney chases that were never reinspected when newer furnaces were swapped in. When venting isn't right for the appliance, exhaust gases - including carbon monoxide - can spill back into the house instead of going up the chimney.

Utah code requires CO detectors in every home with a gas appliance, and that's the most important backstop. But on a pre-1950 Murray home, a furnace tune-up should always include a combustion analyzer reading at the burner - the test that confirms the system is venting cleanly. Every Murray HVAC Pros tune-up does this as a standard step, not an upcharge.
