Aurora questions
Asked by your neighbors.
Hail hit my AC. Is it ruined?
Usually not. Bent fins get combed straight and the unit tests fine. If the coil is punctured we show you the leak and write up both options.
My Aurora home’s builder furnace is 15 years old. Replace it now?
Not necessarily. If it passes a combustion and heat-exchanger check, it can run a few more winters. We test it for $99 and show you the repair-vs-replace math in writing.
Do you cover Southlands and Tallyn’s Reach?
Yes, all the way to E-470. About 25 to 30 minutes from our shop.
Can you fix a system installed by another company?
Of course. We work on every brand and honor manufacturer warranties on the parts.
