AC Tune-up

Take the steps to avoid your air conditioner breaking down in the middle of the hot summer with an A/C tune-up. Our technicians are located locally in the St George, Utah metropolitan area.  You can count on Black Diamond Heating and Air for award winning service.

Air conditioner manufacturers recommend having your A/C tuned-up each season. Some HVAC experts say up to 75% of “no cold air” calls in the summer are related to a lack of maintenance.

Just like your car needs it’s oil changed regularly, your A/C will perform it’s best with regular maintenance. However, if your A/C is not functioning like it should, or not blowing cool air, please call to book a repair service appointment instead of a tune-up.

AC Tune-up, Air Conditioning Service St George Utah

Why is it important to get your A/C tuned-up?

There are many reasons why your air conditioner can develop problems or just stop working when you need it most. A tune-up is preventative maintenance. It is often during preventative maintenance that issues that would otherwise lead to a repair call in the middle of the hot summer, are recognized and resolved.

Living in southern Utah, we rely on our air conditioners for our health and well being. An air conditioner tune-up ensures that your cooling system is ready to handle the strain that combating high temperatures can bring. An A/C tune-up can extend the life of your air conditioner and ensure it will operate as efficiently as possible, which can result in energy savings for you.

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
