“Black Diamond Electric, Plumbing, Heating and Air is the most professional, courteous, and timely AC repair company I have worked with in 15 years. Joel arrived on time and had researched the previous tune ups at my home with the repairmen who took notes. What a great team! He consulted again with them as he problem solved and it was reassuring to know that a whole team was available to solve the problem.
Competitive pricing and great service 5 stars!”

Very impressed with Parker when he stopped by to provide an estimate for a whole house humidifier. He knows his stuff. Unfortunately the existing utilities in our house makes the installation too difficult. Hope to have them replace an AC unit in another property we own.read more

We woke up at 3 am to water dripping through our ceiling. Black diamond was at our home that afternoon to diagnose the problem with our AC. Within 2 days it was fixed. Our repair man was super friendly and got the job done quick. Hopefully we don't have any issues again, but if we do, we will for sure use black diamond again!read more

What an awesome company! Lance came in and did a tune up on our heating and air system. He found a small issue with our contactor, showed me a photo of what he had found, explained why it was a concern, wrote up a quote and even offered to clean up the small amount of dust that'd fallen from the attic. He was professional without being pushy. I'd highly recommend them!read more

Amazing service! Black Diamond Experts sent Lance to clean our furnace. He did a thorough job, didn’t rush, walked us through each step, and gave us a wealth of knowledge for maintaining our furnace. The price was reasonable and he had parts to replace a few things on our current unit already with him. He was not pushy and tried to offer us the most economical options. He was so polite and wasn’t there to make a sale but rather to help us out. Thanks Black Diamond Experts!read more

The Importance of Having Your Furnace Tuned-up

Having a fully functional furnace that you can rely on is essential to healthy living during the colder months of Utah. Just like a car needs maintenance to continue to function at its best, a furnace requires maintenance to stay efficient and catch any problems before they cause your furnace to stop working. Furnace maintenance is often referred to as a tune-up. Our furnace tune-up is a 21 point inspection and also includes a standard filter replacement. 

Furnace manufacturers recommend a yearly tune-up and a regular filter change to ensure the longevity of the life of your furnace. 

It is important to have your furnace cleaned and inspected.

A Quick HVAC Checklist With Reminders

  • Remember to have your furnace and air conditioner tuned-up once a season as manufactures recommend.
  • Be sure to check your furnace filter regularly for cleanliness and change it at least every few months or more frequently if needed.
  • Save energy by programming your thermostat to your schedule.
  • Install proper smoke and carbon monoxide detectors
  • DO NOT use generators inside of a house
  • Call for repairs as soon as irregular noises start happening
