Denver HVAC Repair

Believe it or not, your HVAC system can affect your health. Because the air is recycled in a contained space, airborne particulates like pet dander, allergens, mold, fungi, cleaning chemicals, and more can become a major issue. We specialize in ensuring the indoor air quality of your Northern Virginia home is of the highest level. To this end, we offer a full line of indoor air quality products and services, including air purifiers, ventilators, humidifiers, UV lamps, and air duct cleaning. Our qualified technicians are trained to ensure your family breathes easily.
MacDonald-Miller has developed a unique program to help the Service Department continually evaluate the satisfaction of customers and make ongoing improvements to the level of service provided. Our Customer Experience Commitment encompasses the following elements that help maintain and increase the quality of service delivered by the MacMiller team.
The contactor (relay) and start/run capacitor(s) (see illustration below) fail most often and are inexpensive. So it’s a safe bet to buy and install those parts right away, especially if your air conditioning service unit is older than five years. The condenser fan motor can also fail, but it runs about $150 — hold off buying that unless you’re sure that’s the culprit.
Fast forward 1 year and 1 week and the circuit board that HVAC Service had installed has failed again. They came out and said that it failed from water condensation dripping onto it, so we needed to replace it and reroute the pipes to prevent future water damage. That would cost double what I paid last year. Why didn't they fix the problem last year at the initial repair instead of putting in a circuit board that was bound to fail again?!? They were strongly recommending that the furnace be completely replace for a huge fee to avoid the same thing happening again. I paid $59 for them to tell me they didn't fix it right last year. This didn't feel right, so I sought a second opinion. I'm very glad that I found another guy to come replace the circuit board and put it away from the water, fix the water leak, and also find and fix another impending failure. All of that was for much less than HVAC Service wanted to charge for repair or replacement. The other guy did a great repair, so I'm confident it will not break down again, but if it does, I will not call HVAC Service. Don't get suckered by their Yelp Deal.
If so, you may want to consider replacing your entire AC system. After your AC system reaches a certain age, it makes more sense to invest in a new AC system altogether rather than repairing it one piece at a time. To learn more about John Moore’s AC replacement program, our warranty, and the cost-advantages of replacing your AC system, visit our AC Replacement page.
AC units and thermostats have built-in delay features when they’re shut down and then repowered. The delay can be as long as 10 minutes. And, if you’ve subscribed to an energy-saving device from your local power utility, the unit can take even longer to reset. If you’ve installed the parts shown and reinstalled the disconnect block, repowered the circuit breaker, turned on the switch at the furnace, moved the thermostat to AC mode and lowered the temperature below the indoor temperature, and the unit doesn’t fire up after 30 minutes, it’s time to call a pro.

The standards do not require you to change your existing central air conditioning units, and replacement parts and services should still be available for your home’s systems. The “lifespan” of a central air conditioner is about 15 to 20 years. Manufacturers typically continue to support existing equipment by making replacement parts available and honoring maintenance contracts after the new standard goes into effect.
I was able to get a next day appointment with them last week after multiple other providers did not have availability. The tech was on time and did a good job to diagnose and eventually replace the circuit board and get it up running again. The service itself would be 5 stars, although it did take a week to complete the job due to ordering the part.

AC air handler squealing or grinding noises. Though most air handlers have direct-drive motors, some older units may be belt-driven. Squealing sounds from a belt-drive air handler generally occur when the belt that connects the motor to the blower slips. In most cases, the belt is improperly aligned or worn and needs replacement. Follow the instructions above under Air Conditioner Not Blowing Air and refer to your owner’s manual.

Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.
