Andrew Smith HVAC Services is a local, owner-run HVAC company based in Melissa, TX. We serve homeowners and small commercial property owners across Collin County and the surrounding North Texas communities — including Anna, McKinney, Allen, Plano, Prosper, Celina, Blue Ridge, Princeton, Westminster, Farmersville, Van Alstyne, Howe, Sherman, Gunter, Whitewright, Leonard, and Trenton.
Reach us the way that works best for you — call, fill out the form below, or book online through HouseCall Pro using the Schedule Now button in the header. During business hours, we answer the phone ourselves and give you a real ETA. For no-cool and no-heat calls during summer and winter, same-day response is the standard.
When you submit the form or leave a message, we get back to you the same business day — usually within an hour or two. Please include a brief description of the issue (no cool, no heat, strange noise, high bill, planning a replacement, etc.) and your ZIP code so we can route the call to the right technician and give you an accurate ETA.
For emergencies during business hours, calling is the fastest path — we prioritize no-cool calls during heat waves and no-heat calls during cold snaps. After hours, leave a voicemail with the same details and we will call you back first thing the next morning, or dispatch after-hours emergency service if the situation calls for it.
Common reasons homeowners reach out: AC not cooling, furnace not heating, strange noises from the system, high electric or gas bill, planning a replacement, scheduling twice-a-year preventive maintenance, indoor air quality concerns, or a second opinion on a repair or replacement quote another company has already given you. All of those are worth a phone call — and second opinions are free.
