"I've been in this industry since 2008. I know most of these companies—some are friends, some are competitors, and a few I've cleaned up after. This list reflects my honest professional opinion of who does quality work in Allen. I included Jupitair because I stand behind our team, but I'm also giving you other solid options because the right fit matters more than any one company."

Frequently Asked Questions About HVAC in Allen

What's the average cost of AC repair in Allen?

AC repair costs in Allen typically range from $150-$650 for common repairs. Diagnostic fees average $75-$150, often waived with repair. Major repairs like compressor replacement can run $1,500-$3,000. Always get multiple quotes and ask about diagnostic fee policies. Allen residents should look for contractors familiar with Collin County building codes.

How do I verify an HVAC contractor's license in Allen, Texas?

Texas HVAC contractors must hold a TACL (Texas Air Conditioning License) issued by TDLR. Verify licenses at tdlr.texas.gov. Allen is in Collin County, which may have additional permit requirements for installations. Always confirm EPA 608 certification for refrigerant handling and consider NATE certification for technician competency.

What should I expect to pay for a new AC unit in Allen?

A new AC installation in Allen typically costs $4,500-$12,000 depending on system size, efficiency rating, and brand. With homes averaging 20 years old in Allen, you may also need ductwork updates. High-efficiency units (16+ SEER) cost more upfront but save on energy bills in Texas's hot climate.

When is the best time to schedule HVAC maintenance in Allen?

Schedule AC maintenance in early spring (March-April) before the brutal Allen summer heat arrives. For heating maintenance, aim for early fall (September-October). Avoid peak summer months (June-August) when contractors are busiest with emergency repairs. Spring and fall appointments are easier to schedule and may offer better rates.
