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 Oil questions, answered by experts

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

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

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.
