Gas furnace breakdowns aren’t just inconvenient — they could be risky for your family’s health. We’ve found that many of our customers put off preventative maintenance and small repairs, leading to big breakdowns that result in expensive fixes or even having to install a new gas furnace to get their home comfortably warm again.

Don’t Wait for a Breakdown — Schedule Gas Furnace Maintenance Today!

Instead of waiting until your furnace just stops working altogether, schedule preventative maintenance with Donnelly’s Plumbing Heating and Cooling! We provide gas furnace service, installation, and repair in Lansdale, Ambler, and other towns throughout four counties in Southeastern Pennsylvania. With 24-hour service, we can be there to help whether your gas furnace goes out at 2 in the afternoon or starts making an alarmingly loud noise at 3 AM.

At Donnelly’s, we guarantee our friendly, clean-cut, and experienced technicians will dedicate themselves to ensuring that your gas furnace is back up to speed in no time at all. We’ve been in Lansdale, PA for decades and many of our customers have been with us for just as long.
