Red Mountain Heating and Air, Inc is dedicated to providing our customers with the best quality and craftsmanship. We are here to build relationships with our customers and communities and to provide our employees with a great place to work. We look forward to working with you!

"I got bids from a *large* number of installers and Red Mountain gave me the best equipment for the price and did a nice job of it despite a few early teething problems that were resolved quickly and competently. But note that the going price in this area for heat pumps is significantly higher than in other areas of the country - regardless of which installer I let bid on my home. In my opinion, given energy price trends, the environmental impact of heating with gas, and having existing solar power on my home, the benefits of a heat pump outweighs the high price in this area, but YMMV. Think thru your position re: BayREN rebates and the recent federal Inflation Reduction Act rebates carefully to make sure you qualify."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

Heating Oil questions, answered by experts

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
