What it costs
Questions we get every week.
(469) 389-0525What does a diagnostic visit cost?
$75. Veterans and military families get a discount, so mention it when you call. We price the repair after we’ve looked at the system.
Do you charge more for nights and weekends?
We’re open 24/7. A night or weekend call adds $100 to the visit.
Who will come to my house?
One of our own techs. Every Forefront employee passes a drug test and a background check before they work in anyone’s home.
Should I repair my system or replace it?
Multiply the system’s age by the repair quote. Past 5,000, the money usually does more toward a new system. Under 3,500, repair it. In between, get both prices.
