Cornerstone Cooling & Heating

Cornerstone is a veteran-owned heating and air company in the Denton area. We work on homes and light commercial buildings. Every repair is quoted from a set flat-rate book and you approve it in writing before work starts. If the job runs long, that’s our problem, not yours. The price you approved is the price you pay. What you can count on: Licensed and insured. Texas HVAC License TACLB156738E. Veteran-owned. We hold ourselves to the same standard of showing up, telling the truth, and finishing the job right. No upselling. We’ll tell you if a repair makes sense or if your system is worth replacing, and we won’t push either one. We answer nights and weekends. Weekday hours are 8am–6pm. After hours, you’ll still reach a real person. We’re a small, local company, so every customer counts. Give us a shot and we’ll earn your review.
