How booking works
The booking window opens on its own. If it didn't, tap Book online, or call the office at (301) 880-3248, Monday–Friday, 8 AM–5 PM.
- Tell us what's going on. A repair, a tune-up, or an estimate for a new system. A few quick questions help us send the right tech with the right parts.
- Pick a day and an arrival window. You see the openings we actually have, and you choose.
- We confirm by text. You get a reminder before the visit and a text when your technician is on the way.
- Upfront pricing at your door. Your technician explains what's wrong and gives you the price before any work begins. No surprise fees.
We serve homes and businesses across St. Mary's and Calvert counties, Monday through Friday, 8 AM to 5 PM. For a gas smell or a carbon monoxide alarm, leave the house and call 911.
