How much does AC or furnace repair cost in Denton?
It depends on what's wrong and which part needs replacing. We use flat-rate pricing: a licensed technician diagnoses the problem and shows you the price before starting, and that price doesn't change if the job takes longer. Repairs come with a 1-year warranty.
How much does a new AC or HVAC system cost in Denton?
The price depends on your home's size, the type of system, its efficiency (SEER2 rating) and the condition of your ductwork. Our Instant HVAC Quote shows you system options and price ranges online in a few minutes, with no appointment needed. Then we confirm everything with a free, no-pressure in-home visit.
Do you offer HVAC financing?
Yes. Approved customers can choose $0 down with no payments and no interest for up to 18 months, or $0 down with payments as low as $110 a month and no penalty for paying early. Financing is through GoodLeap and subject to credit approval.
Do your repairs come with a warranty?
Yes. Repairs come with a 1-year warranty. Energy Saving Agreement members get a 3-year repair warranty, and Express Comfort members get a 2-year repair warranty.
Should I repair or replace my AC or furnace?
Replacement usually makes sense when your system is 12 to 15 years old or older, still uses R-22 refrigerant, needs a repair that costs close to half the price of a new system, or your energy bills keep climbing. We give you upfront prices for both options so you can decide.
How often should I service my AC and furnace in North Texas?
Twice a year: the AC in spring before the heat arrives, and the furnace or heat pump in fall. Energy Saving Agreement members get both tune-ups included, priority same-day service and 15% off repairs. Express Comfort members get $89 tune-ups and 5% off repairs.
What should I check before calling for AC or heating service?
Check that the thermostat is set to Cool or Heat with fresh batteries, reset any tripped breakers for the indoor and outdoor units, and replace a dirty air filter. Our HVAC Troubleshooting page walks you through each step, and you can order filters from our online filter store.
