Frequently Asked Questions About HVAC in Addison

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

AC repair costs in Addison 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. Addison residents should look for contractors familiar with Dallas County building codes.

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

Texas HVAC contractors must hold a TACL (Texas Air Conditioning License) issued by TDLR. Verify licenses at tdlr.texas.gov. Addison is in Dallas 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 Addison?

A new AC installation in Addison typically costs $4,500-$12,000 depending on system size, efficiency rating, and brand. With homes averaging 35 years old in Addison, 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 Addison?

Schedule AC maintenance in early spring (March-April) before the brutal Addison 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.
