$69 Furnace Tune Up! | Get a new AC & Furnace for as low as $90/month with approved credit!
Utah summers are relentless. When your air conditioner fails, it isn’t just an inconvenience—it’s a disruption to your life and a threat to your home’s air quality. A malfunctioning system creates a chain reaction of high humidity and skyrocketing energy costs as your unit desperately tries to compensate for failing parts.
At Efficient Systems Heating & Cooling, we don’t believe in temporary patches. Our “Efficient Standard” means performing a comprehensive forensic diagnostic to find exactly why your system failed. We identify the root cause—whether it’s a burnt capacitor, a seized motor, or a refrigerant leak—ensuring that once we restore your cooling, it stays restored.
As a family-owned business, we treat your repair with the urgency it deserves, getting your home back to a sanctuary of cool air without the stress of a “return visit.”
Most AC systems don’t fail without warning. Usually, your unit will “signal” for help through performance drops or unusual behavior. Recognizing these signs early can be the difference between a simple part replacement and a total system meltdown.



Choosing a repair team is about more than just fixing a machine; it’s about inviting a professional into your sanctuary. At Efficient Systems Heating & Cooling, we’ve built our reputation in Murray and across the Salt Lake Valley by obsessing over the details that other companies overlook.
When you trust us with your home, you aren’t just getting a technician—you’re getting a commitment to integrity, speed, and precision.

I highly recommend William.Posted on Neil MilneTrustindex verifies that the original source of the review is Google. William came over on a Sunday night to check out our heater, he had to order a part that was under warranty, the part came in the next day and our furnace was fixed. I tried to pay him but he said it was under warranty. I was amazed, thank you so much!Posted on Rich EvansTrustindex verifies that the original source of the review is Google. William was great! He knew exactly what the problem was within 5 minutes and how to fix it. He also took the time to answer a lot of questions I had related to how to really know when you should or need to replace your furnace/AC unit. He was recommended to us and we recommended him to our friends!Posted on Richard PachecoTrustindex verifies that the original source of the review is Google. Great service and always on time.Posted on William R SpencerTrustindex verifies that the original source of the review is Google. Always fast friendly service, left three space heaters to keep pipes from freezing.Thank You! William Chaves and Bernadette for making it happen.Posted on Giles HallTrustindex verifies that the original source of the review is Google. We had another company come out who told us our only option was to replace both our furnace and AC — at a huge cost — and they were really pushing for a quick decision. Thankfully, we decided to get a second opinion, and a friend recommended William so we gave him a text and he came quickly. He was thorough, honest, and went above and beyond to actually figure out what was going on instead of just trying to sell us something new. He took the time to explain everything clearly, showed us what was really needed (which turned out to be much less than a full replacement), and got everything running perfectly. You could tell he genuinely cared about helping us, not just making a sale. It’s rare these days to find someone this professional and trustworthy. We saved a ton of money and learned a lot in the process. We’ll definitely be calling him for all our HVAC needs going forward. Highly recommend — if you want someone honest, skilled, and looking out for you, this is the person to call.Posted on Ibrahim RamazaniTrustindex verifies that the original source of the review is Google. I've worked with William on many occasions, such an honest and professional guy. Efficient System provides fantastic service.Posted on Jake MechamTrustindex verifies that the original source of the review is Google. William was extremely helpful and quickly fixed our furnace. I was worried after going through several vendors and getting different bids that the price for repairs was going to be expensive, but our bid was very reasonable and have had no issues with the system since the repairs. Will definitely reach out again for future repairs.Posted on Nguyen ChienTrustindex verifies that the original source of the review is Google.
