Just give us a call, and we’ll be happy to help.

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

At Allred Heating, Cooling & Electric, you’re working with a family you can trust — twin brothers Dan and Matt Allred. Matt started as an electrician over a decade ago and expanded into HVAC. Dan spent years as a contractor in Alaska. Together, their complementary skills created the perfect team to deliver reliable, whole-home electrical and HVAC service. We know you'll appreciate our family-owned business because we know the importance of safety, comfort, and fair pricing. We provide upfront estimates, expert installation and repair, and a full one-year parts and labor guarantee. Licensed, bonded, and insured — we’re here to earn your confidence and keep your home running perfectly all year long.

"I recommended AllRed to my mother, they told her that they would give her a 10% discount on the phone when she called. They only gave her a 5% discount, they also didn't provide any information about the system? No information was provided also about health of system or checkpoint system used; (PSI of freon, lubrication, filters, drain lines, etc) When I called up Allred and asked for them to provide the 10% discount like they promised they said they would, and she would see it on her Credit Card. A couple of weeks went by and nothing. I called again, they apologized and said they would follow up ensure that the service team sent the information to us and provided the discount and called me back directly. After another week, NOTHING! While the work was completed successfully. The communication and follow up of this company are terrible to say the least. I wouldn't recommend Allred to anyone, or trust them at all :-("

Heating and Air Conditioning questions, answered by experts

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Good news: Your AC system doesn’t need Freon (a popular refrigerant) added regularly, if ever. Freon only needs to be added when there’s a refrigerant leak; however, it’s not uncommon for a gradual leak to occur every 5 to 15 years. Signs of a refrigerant leak include higher utility bills, increased humidity in the house, weakened AC performance, and a hissing sound from the system.

The cost of a new HVAC system is roughly $7,500 but will vary by the type of HVAC unit and the size of your home. If you only need to replace your AC, it can cost between $2,200 and $5,500; replacing your furnace costs $3,200 to $6,000.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.
