Gladwyne, PA Plumbing and HVAC Services

In 1959 Joseph J. Walsh Sr., a Korean War veteran, established Walsh Brothers Plumbing and Mechanical Services, Inc. to fix the needs of friends and family in the area with quality workmanship, fast service, and competitive pricing. 60+ years later, though the business has changed, the priorities have not. Not just in the greater Gladwyne, PA area, but throughout the rest of our service areas, we realize that not everyone can afford the most expensive HVAC system or plumbing repair. We know that there are affordable solutions for every home and every budget.

We’ve been around the block. Don’t hesitate to call us. Fast-Friendly-Reliable. Contact us today!


Are you having perpetual problems with your kitchen appliances? Does your gas stove have trouble turning on? Is your sink drain clogged? We’re the one call stop. From garbage disposal repair to gas pipe installation, to any other type of plumbing problem, we can help. You don’t want to wait days or weeks for a handyman to tighten valves and figure it out as they go. Contact us, the professionals, when it comes to plumbing services.

Emergency Plumbing

Overflowing drains can be dangerous for your property and your health. Leaking wastewater or excess overflow can lead to mold growth, water damage, and the destruction of electronic appliances. Why settle for anything less than the best? We’re available 24/7 to take your call, no matter how complex the plumbing issue. Plumbing problems in Gladwyne, PA don’t ever happen when they’re convenient- that’s why we know you want fast, friendly, and reliable emergency plumbing service.

Drain and Sewer

Drain clogs are disheartening. When you constantly try to snake a drain to no avail, sometimes it feels like nothing will work. That’s where we come in. We’ve got powerful hydro-jetting technology to blast whatever is clogging your drain out. We jet pressurized water into your drains, dislodging anything stopping your drain from working. Your sewers and drains are an important part of your home, which is why you should contact the professionals to unclog them in record time. Trust us with your drain cleaning needs.

Air Conditioning

In our 60+ years of home service, we’ve kept up to date on the most environmentally friendly and economically efficient air conditioning systems. We’ve taken the time to procure the most effective AC brands like Bryant. But we don’t stop there, we install innovative systems like Geothermal heating and cooling. Harness the heating and cooling power of the earth’s crust by allowing us to install a year-round, environmentally sustainable cooling system that will cut your energy bills in half. We have all the air conditioning services you could ever need.


We’ve been installing boilers, furnaces and heat pumps in Gladwyne, PA for years. We know these systems thoroughly and can install them quickly and efficiently. What about the more unconventional systems? We install and maintain geothermal technology as well, performing year-round cooling and heating at a fraction of the energy cost of a conventional heater. Does geothermal sound too expensive to install? No problem, we perform ductless heat pump installation that performs dual heating and cooling as well.

Indoor Air Quality

Air temperature doesn’t tell the full story. The quality of the air you breathe can tell a lot about your health and the health of your family. Not only do we install and maintain air purifiers that kill almost all bacteria cells while catching viruses, but we also install Aprilaire humidifiers and dehumidifiers. Humidifiers, especially during winter when colds and flus are easy to catch, can help the body’s immune system and fight illness. Let us keep your indoor air quality high.

Water Heaters

You’ve probably heard about tankless water heaters- but believe us when we say they’re not for everyone. Don’t worry, we won’t try to upsell you for an extra buck. If you’re looking for a system that can be cheaply installed while being able to provide high pressure water in your showers, sinks, and appliances, look no further. With gallons of preheated water at the ready, your water tank needs will be met by calling us. We install and service a wide range of water heaters.

Whether it’s the installation of a powerful rooftop AC unit, emergency drain clog service, or building-wide sewer installation, you need the job done fast.
