Questions, answered

Every repair and installation comes with a 1-year labor warranty on our work, plus a 5-year manufacturer parts warranty. More on our home page

Usually within 1-2 days, and same-day when the schedule allows. Comfort Club members get priority scheduling. More on our home page

$79, flat. That covers the visit and diagnosis. If you go ahead with the repair, the $79 comes off your final bill, and we quote the repair flat-rate before starting. More on our home page

Yes. Utah contractor license #12914771-5501 (S350 HVAC classification), active and in good standing, plus general liability insurance. More on our home page

No. We work seven days a week at the same rates. More on our home page

Most often low refrigerant, a dirty coil, or a failing capacitor. The $79 diagnostic pins it down. More on AC Repair

Yes: Lennox, Carrier, Trane, Goodman, Rheem, Bryant, and the rest. More on AC Repair

When the schedule allows, yes, and July fills up fast. Call early in the day. More on AC Repair

Thermostat set to cool, air filter not clogged, breaker not tripped. Two minutes of checking sometimes saves you $79. More on AC Repair

Often a flame sensor, ignitor, or a clogged filter causing overheat shutdowns. The diagnostic tells us which. More on Furnace Repair

No-heat calls jump the queue in winter. Call 385-526-4111 rather than booking online for these. More on Furnace Repair

Yes, and we are honest when a unit is past the point where repairs make sense. More on Furnace Repair

Yes: it keeps the warranty valid on most brands, catches carbon monoxide risks, and cuts mid-winter breakdowns. It is included in the Comfort Club. More on Furnace Repair

Most straight swaps are done in one day. More on AC Replacement

Home size, ductwork condition, and efficiency tier. The free estimate turns the range into one exact number. More on AC Replacement

Yes, in-home replacement estimates are free and take about 45 minutes. More on AC Replacement

We pull required permits, and we will flag any current Rocky Mountain Power rebates your chosen system qualifies for. (The federal 25C tax credit ended for systems installed after December 31, 2025.) More on AC Replacement

Yes, and we prioritize no-heat replacements. Most swaps take one day. More on Furnace Replacement

It is the share of every gas dollar that becomes heat instead of going out the flue. The free estimate includes payback math for your actual usage. More on Furnace Replacement

If both are 12+ years old, a combined install saves real money on labor. We quote it both ways and you choose. More on Furnace Replacement

Yes. Enbridge Gas (ThermWise) offers a rebate of $300 for a 95% to 97.4% efficient furnace, and $350 for 97.5% or higher with an ECM blower. The request has to be submitted within six months of install, and we give you the model and efficiency details you need for it. Enbridge sets the amounts and can change them, so we confirm the current rebate on your estimate. More on Furnace Replacement

It is real, it can leak carbon monoxide, but it is also the most abused line in HVAC sales. We show you the crack on camera or we do not say it. More on Furnace Replacement

No. In Salt Lake City and South Salt Lake we only do free estimates and installation of new systems. Repairs, tune-ups and diagnostic visits stay in our full-service area, from Herriman north to Murray. More on Salt Lake City

Most straight swaps of a furnace or air conditioner are done in one day. Jobs that need new venting, a chimney liner or duct changes can take longer, and we tell you that on the estimate. More on Salt Lake City

Every installation comes with a 1-year labor warranty on our work, plus a 5-year manufacturer parts warranty. More on Salt Lake City

No. The monthly plan is month to month and the annual plan renews once a year. Cancel either one anytime and you will not be charged again. More on Comfort Club

Yes, within the first 30 days of an annual membership, as long as we have not been out for your first tune-up yet: we refund the full $199.90. After that, annual memberships are not refundable, but you keep every benefit until the end of the year you paid for and you will not be charged again. Monthly members are simply not charged again after they cancel. More on Comfort Club

Had your $95 tune-up? Join the annual plan during that visit and the $95 counts toward it. You pay $104.90 instead of $199.90 for the first year, that visit is your first Club tune-up, and one more is included. It renews at $199.90. Your tech sets it up with you on the day. Because your first tune-up is already done, the 30-day refund does not apply to this offer. More on Comfort Club

Same membership, same benefits. Monthly is $19.99 a month. Annual is $199.90 paid once a year, which is ten months for the price of twelve and saves you $39.98. More on Comfort Club

A multi-point inspection and service: coils, refrigerant charge, capacitors, ignition, flame sensor, heat exchanger and CO check, filter, thermostat calibration, and a written condition report. More on Comfort Club

Yes, landlords love this: we coordinate directly with your tenant and send you the report. More on Comfort Club

Yes, it can transfer to the new owner, which is a nice selling point. More on Comfort Club

Yes. Mountain Star is based in Herriman. It is not a dispatch address for a company somewhere else. More on Herriman

Usually within 1-2 days, and often sooner, because Herriman is home base. Comfort Club members get priority scheduling. More on Herriman

Heat rises, and a single system in a two-story home has to push cool air the farthest to reach the top floor. Dirty filters, closed or unbalanced dampers and too few return vents upstairs make it worse. We measure the airflow before suggesting anything bigger, like zoning or a second system. More on Herriman

At that age we quote both and show you the math. No pressure either way. More on Herriman

It is roughly a 10-minute drive from our Herriman base to most of Riverton, and appointments are usually available within 1-2 days. More on Riverton

Not automatically. Age alone is not a reason. We check the heat exchanger, venting and safety controls, tell you what the repair costs, and quote a replacement next to it so you can decide. More on Riverton

Often, yes. Many R-22 repairs are electrical or mechanical and need no refrigerant at all. If yours does need refrigerant, we tell you the cost first, because it is expensive now that R-22 is no longer produced. More on Riverton

Yes: Lennox, Carrier, Trane, Goodman, Rheem, Bryant, and the rest. More on Riverton

Yes. Daybreak is part of South Jordan and one of the closest areas to our Herriman base. Most visits are booked within 1-2 days. More on South Jordan

Yes, we can diagnose and repair them. If a repair is still covered by a builder or manufacturer warranty, we will help you figure out which route makes sense before you pay out of pocket. More on South Jordan

On high-efficiency furnaces this is very often a blocked condensate drain or a pressure switch fault, which stops the furnace on purpose to keep it safe. It is usually a straightforward repair, diagnosed for the flat $79 service call. More on South Jordan

Often, yes. A load calculation tells us what your home actually needs, and an oversized system costs more, cycles on and off and wears out sooner. More on South Jordan

Bluffdale borders Herriman, our home base. Visits are usually available within 1-2 days, and often sooner. More on Bluffdale

Yes. We work on both: larger, older systems on acreage lots and newer builder-grade units in the subdivisions. More on Bluffdale

Yes. We diagnose and quote each system separately, so you can fix or replace one at a time. For the Comfort Club on more than one system, call 385-526-4111 and we will set it up. More on Bluffdale

In larger homes the rooms farthest from the furnace sit at the end of the longest duct runs. Leaky or undersized ducts, closed dampers and missing return air are the usual causes, and they can often be fixed without new equipment. More on Bluffdale

West Jordan is a short drive north of our Herriman base, with the southern and western parts of the city closest. Visits are usually available within 1-2 days. More on West Jordan

Warm air rises to the upper levels, and lower levels often have fewer supply vents and weak return air. Adjusting dampers, clearing returns and checking the blower speed fixes a lot of it before anyone talks about new equipment. More on West Jordan

Not always. Many duct systems only need sealing or a better return. We inspect them on the free estimate and tell you plainly whether they will hold back a new furnace. More on West Jordan

Kearns is a short drive north of our Herriman base, usually 15 to 20 minutes depending on traffic. Visits are usually available within 1-2 days. More on Kearns

Yes, as a new air conditioner installation. On a free in-home estimate we check whether your existing furnace ducts and return air can carry central air, what electrical work it needs, and give you three options with exact pricing. More on Kearns

Usually not enough air moving across it: a clogged filter, a weak blower, or ducts too small for the AC. Low refrigerant can do it too. We find which one for the flat $79 service call. More on Kearns

It can be, if the heat exchanger, venting and safety controls check out. Age makes those checks more important, not optional. Keep working carbon monoxide alarms in the home whatever the furnace's age. More on Kearns

Usually 15 to 25 minutes north of our Herriman base, depending on where in Taylorsville you are and on traffic. Visits are usually available within 1-2 days. More on Taylorsville

Yes. We schedule access with your tenant, do the work you approve, and send you the details. Comfort Club landlords get the tune-up reports too. More on Taylorsville

Yes. Tell us about your HOA's rules on condenser placement and noise when you book, and we will plan the install and the quote around them. More on Taylorsville

Most of West Valley City is 20 to 25 minutes north of our Herriman base, depending on traffic. Visits are usually available within 1-2 days. More on West Valley City

Swamp coolers work well in Utah's dry heat and cost little to run, but they struggle on humid summer days, need seasonal startup and shutdown, and bring in outside air during inversions and wildfire smoke. Central air uses your furnace ducts and filter. We price it on a free estimate so you can compare. More on West Valley City

Yes, all of West Valley City: 84119, 84120 and 84128. More on West Valley City

Murray is about 20 to 25 minutes north of our Herriman base, depending on traffic. Visits are usually available within 1-2 days. More on Murray

Full service. In Murray we do repairs, tune-ups, diagnostic visits and replacements. Salt Lake City and South Salt Lake are the areas where we only do free estimates and new installs. More on Murray

It can. A high-efficiency furnace vents through its own plastic pipe, which leaves the water heater alone in a chimney sized for two. That can stop it venting properly, so the chimney may need a liner. We check this on every replacement estimate and include it in the price. More on Murray

Often, yes. Older homes commonly have small or too few return vents and duct runs that were extended over the years. We measure the airflow and tell you what would actually help before quoting any equipment. More on Murray
