Terms of Service

Effective October 21, 2026

These terms apply to mountainstarhvac.com and to service provided by Mountain Star Heating and Cooling LLC ("Mountain Star", "we", "us"), a Utah licensed HVAC contractor (Utah Contractor License #12914771-5501, S350 HVAC) based in Herriman, Utah. By using the site, booking with us or texting with us, you agree to these terms. Any written quote or agreement for a specific job also applies, and where it differs from this page, the written quote or agreement wins.

Who we serve

We offer full service (repairs, tune-ups, diagnostics and replacements) in Herriman, Riverton, South Jordan, Daybreak, Bluffdale, West Jordan, Kearns, Taylorsville, West Valley City and Murray. In Salt Lake City and South Salt Lake we offer free in-home estimates and installation of new furnaces, air conditioners and heat pumps only, not repairs, tune-ups or diagnostic visits. We may decline a job outside these areas.

Quotes and pricing

• Repair visits carry a flat service call fee, currently $79, which covers the visit and diagnosis. If you go ahead with the repair we recommend, the service call fee is credited on your final bill.
• We quote repairs at a flat rate before we start. We do not begin paid work without your approval.
• In-home replacement estimates are free. Written replacement quotes show the price for your home and are valid for the period stated on the quote.
• Prices on this website are a guide and can change. The price on your written quote or approved invoice is the price you pay.
• If we find something during a job that changes the scope, we stop and explain it before doing extra work.

Appointments

Online bookings and callback requests are requests until we confirm them. If you need to reschedule or cancel, please call or text us as early as you can so we can offer the time to someone else. Someone 18 or older who can approve work should be home for the visit, and we need safe access to your equipment, including attics, crawlspaces and the outdoor unit.

Payment

Payment is due when the work is complete unless your written quote says otherwise. Online payments and Comfort Club memberships are processed securely by our payment processor, Stripe. If financing or monthly payment options are offered, they are provided by a third party under its own terms and approval.

Warranty

Every repair and installation comes with a 1-year labor warranty on our work, plus a 5-year manufacturer parts warranty. Manufacturer parts warranties are provided by the equipment manufacturer under its terms, which can include registering the equipment and keeping up regular maintenance. Our labor warranty does not cover damage from misuse, accidents, power surges, flooding, lack of maintenance, or work done on the system by someone else after our visit. If something we did is not right, call us first and we will make it right.

Comfort Club membership

The Comfort Club covers one full system (furnace and AC) with two tune-ups a year, priority scheduling and 10% off repairs. The monthly plan ($19.99 a month) is month to month. The annual plan ($199.90 a year) renews once a year. You can cancel either plan anytime and you will not be charged again. Annual memberships can be refunded in full within the first 30 days, as long as we have not yet done your first tune-up; after that they are not refundable, but you keep every benefit until the end of the year you paid for. Membership details on the Comfort Club page are part of these terms.

Text messages (SMS)

When you give us your mobile number through our website, booking calendar, chat or in person, you agree to receive calls and texts from Mountain Star Heating and Cooling about your request and your service.

• Program: Mountain Star Heating and Cooling customer care messages: replies to enquiries, appointment confirmations and reminders, on-the-way notices, follow-ups about quotes and completed work, Comfort Club tune-up reminders, and review requests.
• Message frequency varies. Message and data rates may apply.
• Reply STOP to opt out at any time. Reply HELP for help, or call 385-526-4111.
• Consent to texts is not a condition of buying any service.
• Carriers are not liable for delayed or undelivered messages.
• Mobile information and SMS opt-in consent will not be shared with or sold to third parties or affiliates for marketing purposes. See our Privacy Policy.

Using this website

The information on this site is general and provided to help you understand our services. It is not a substitute for an in-person diagnosis of your system. Please do not submit anyone else's information without their permission, or use our forms to send advertising or anything unlawful. The site's text, photos and logo belong to Mountain Star and may not be copied for commercial use without permission. Other websites we link to, such as payment pages, booking calendars and maps, are run by those providers under their own terms.

Safety

If you smell gas, leave the home right away and call your gas utility's emergency line or 911 from outside. If a carbon monoxide alarm sounds, get everyone outside and call 911. Do not wait for a callback from us in either situation.

Limits on our liability

To the extent Utah law allows, we are not liable for indirect or consequential losses, such as lost use of your home, arising from the website or from a delay in service. Nothing in these terms limits any right you have under Utah law that cannot be limited, or our responsibility for our own workmanship under the warranty above.

Governing law

These terms are governed by the laws of the State of Utah. If we ever have a disagreement, we would much rather sort it out on the phone first.

Changes

We may update these terms from time to time. The version on this page, with its effective date, is the one that applies.
