Services
AC Repair
We help restore dependable home cooling through professional AC diagnostics and repair. Warning signs such as warm air, weak airflow, frequent cycling, unusual noises, odors, or water leaks can indicate developing problems. Our process identifies the source rather than applying temporary fixes, while transparent pricing ensures you know the repair cost before authorized work begins.
A/C Installation & Replacement
We provide professional A/C installation and replacement designed for Utah homes and dry heat. Our technicians calculate the homes cooling load to determine proper equipment sizing rather than relying on guesswork. We inspect ductwork, complete clean and code-compliant installations, and verify airflow and efficiency before leaving, supporting reliable performance and lasting comfort.
AC Tune-Up
Before summer demand peaks, our $25 AC tune-up examines the operating condition of your cooling system. We review airflow, filters, blower cleanliness, electrical components, refrigerant measurements, drains, and outdoor equipment. By identifying restrictions, wear, or other concerns early, we provide homeowners with a clearer understanding of system health and recommended corrections.
Furnace Repair
Our furnace repair service begins with a comprehensive inspection of the system, including ignition components, blower motors, and safety switches. We explain the diagnosis clearly and present repair or replacement options without pressure. Before work begins, we provide the exact cost. After completing the repair, we conduct a safety cycle test to verify proper operation.
Heat Pump Installation
A heat pump can serve as both your home's heating and cooling system, and we install these systems with careful attention to proper sizing. Our licensed technicians perform a Manual J calculation and inspect existing ductwork for potential cleaning or sealing needs. We offer no-pressure proposals, maintain a tidy workspace, safely remove old equipment, and confirm correct operation afterward.
Mini Split Installation
We specialize in installing ductless mini splits that combine efficient heating and air conditioning in compact equipment. Our approach eliminates the need for invasive ductwork while allowing room-by-room temperature control. Depending on the application, we can install a single-zone system for a specific space or a multi-zone arrangement for several rooms.
Duct Cleaning
We clean residential duct systems using a structured four-step process designed to provide thorough results. First, we assess the registers and ductwork for buildup or underlying issues. Next, we protect your home and establish negative pressure. Specialized vacuums and agitation tools remove debris, followed by a final walkthrough to confirm everything is secure.
Indoor Air Quality
Utah homes can face very dry winter conditions, trapped inversion pollution, seasonal allergens, and limited fresh-air exchange. We address these concerns with indoor air quality services that include humidification, filtration, purification, UV lights, air scrubbers, and ventilation. Our licensed technicians assess your current system and present clear choices. Installation is completed professionally, with testing afterward.
Plumbing Services
We bring the same commitment to precision, cleanliness, and technical skill to our residential plumbing services. Licensed technicians handle water heater repair and replacement, leak detection, faucet and fixture installation, garbage disposals, and pipe repairs. We begin by understanding the problem, determine the appropriate solution, and explain the work and pricing clearly before proceeding.

Always great service. Today we had Daniel come out for our yearly inspection, he quickly identified an issue with the AC unit and is already working on getting it repaired under warranty. I always appreciate the way North Star techs go out of their way to take care of us. Great service, as usual.

North Star is The Best HVAC company Ive ever dealt with, and Im an old HVAC and pipe insulator! Dillon Neilson was my technician, and he taught me about the A/C system and condenser. Explained maintenance and answered all my questions and concerns. This company is top notch from their coordinator/scheduler, technicians, and owner! If you need anything, they got you covered with the best staff, products, and service. Thank you North Star!

My experience with Northstar was 5-star. My mom has a membership with another company. Last night this other company serviced her furnace and told her she needed a brand new furnace that would cost her $14K for reasons I don't understand. He turned off her furnace and refused to turn it back on despite her request as she didn't believe anything was wrong with it. Important note - my mom is 83, had heart surgery two years ago, and it was 20 degrees last night. Unreal!
Long story shortened, I called Northstar at 8:00 last night. The dispatcher was so kind and because of our situation had someone come out first thing this morning. I am sure you can guess the outcome....nothing wrong with the furnace. Danny turned it back on and went above and beyond to help us. I will always use this company going forward. My mom is cancelling her subscription with this OTHER well-known company. So grateful for good people in the world who live with integrity and honesty. I would refer them to anyone!!!!

We had North Star clean our ducts and service our AC/Heater. They we're really great! They offered to work on a Saturday for us, even though that wasn't their normal hours. And was very open about what they were doing, and why. Also, bonus! They were actually on time and very respectful, and surprisingly quick.

Our heater stopped working during the night. We called for help and Dillon responded, an hour earlier than expected. He was very friendly and respectful, explained what he was doing every step of the way. Within a half hour, he had us up and running with a follow up plan. We were impressed with his knowledge and bedside manner.
