Reviews of local pros in Murray, Utah

This was a wow experience. William was able to come over maybe 30 minutes after I called and requested an appointment. He knew the problem right away and got it fixed very quickly. We’re back up and running! Thank you! Chatting with the lady that scheduled me was easy and great.

I have used efficient systems for the last couple of years. Every time they have been quick to arrive, fairly priced, and honest. They are very professional and friendly. I recommend them to anyone looking for quality, affordable and professional service. This company and service is one of a kind in the best way possible.

Always fast friendly service, left three space heaters to keep pipes from freezing.Thank You! William Chaves and Bernadette for making it happen.

I had William replace my old swamp cooler and install a new A/C and Furnace. He did it for a great price and did a great job. He was willing to answer questions the entire way through and made sure I was happy with the results!

I've worked with William on many occasions, such an honest and professional guy. Efficient System provides fantastic service.

The service was great. The technician was knowledgeable, friendly, and did a great job. He explained everything he was doing and was able to quickly repair our furnace. We were able to get a same day appointment. The repair cost was reasonable. I will definitely use this company again. I’m very happy with my experience.

I was referred to this company from another happy customer have used this company on 5 separate occasions they are very knowledgeable and very competitive prices for complete change outs and repairs.

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.

We had problems in January. William came out very quickly! He is professional and personal. Great service!

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!

They were there right on time and worked hard to replace my old furnace and central air. William is friendly and easy to work with and does a fantastic job. They cleaned everything up and checked to make sure everything was working well. The final cost was as stated and was a great price. I am glad we called them. They have a great warranty too.

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!

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.

I had a fantastic experience with William. Chavez . He is the Heating Technician that came to my house to fix the furnace . He always arrived on time, and very professional fixing my issue with the heater. He explains the problem and gives a fair price to fix the problem. I’m very grateful for his honesty. He is there to help you and not taking advantage of over pricing you. He is very trustworthy. I recommend William to everyone.
