HVAC & Plumbing Services in Mt. Lebanon, PA
Mt. Lebanon is one of the old Pittsburgh neighborhoods we know before we ring the doorbell. Tell us the decade your house was built and we can usually tell you what we will find, we even wrote up the headaches we spot in old Pittsburgh homes.
Heating Services in Mt. Lebanon, PA
A lot of Mt. Lebanon houses went up between the 1920s and the 1950s: lime plaster walls, not much insulation, and heat loss a modern builder would never allow. Plenty of them still run steam or hot water radiators.
Our honest take: radiator heat is some of the most comfortable heat there is, and we usually talk people out of ripping it out. We work on boilers and radiators every week, and we go just as deep on furnaces and modern systems.
Want to know what your decade of house hides? We broke down what we expect from each era of Pittsburgh home.

Air Conditioning Services in Mt. Lebanon, PA
Most Mt. Lebanon homes were built before central air existed. The duct systems that do exist were designed for heating, not cooling, and the houses with radiators have no ducts at all.
We have solved both problems a hundred ways, from properly sized central air conditioning to Mitsubishi ductless systems that cool a radiator-heated home without tearing out a single wall.
When we install an air conditioner, we commission it with digital manifolds, not old analog gauges, so the refrigerant charge is dialed to exactly what the equipment wants. Too much or too little quietly wrecks efficiency and shortens the life of the compressor, and you would never know until the bills climb.

Plumbing Services in Mt. Lebanon, PA
The pipe in a mid-century Mt. Lebanon home is at the age where things show up. Here is what we find most often:
We will tell you this straight: run a camera down any sewer lateral that is not brand-new PVC and it will almost always turn something up. In pipe this old, that is expected wear, not an emergency.
That is why you should always get a copy of your sewer video, a dated recording you can verify is your own line, even when the inspection turns up nothing wrong.
- Galvanized water lines closing down from the inside
- Cast iron stacks rotting from the bottom
- Terra-cotta sewer laterals with roots finding every joint
- What the camera usually finds: a joint that has shifted, a low spot holding water, or roots working their way in
- An honest read on how serious the problem actually is, with real choices to match: a drain cleaning, a repair, or a full repipe or sewer replacement
- Licensed plumbing team with a master plumber on staff behind every job
- You approve a flat, upfront price before a wrench comes out
- Drain cleaning
- Leak detection and repair
- Faucet and fixture repair and installation
- Gas line services
- Toilet repair and installation
- Sewer line repair and replacement
- Water line services
Water heaters and water quality
If your water heater is an old natural draft unit venting up the chimney, it deserves more than a passing look. Those chimneys were built for an older world, and when one gets blocked, combustion gases can spill back into the home instead of leaving it.
So when we look at water heaters, we check how the thing vents, not just whether it makes hot water. Then we help you weigh a repair against a replacement honestly, tank or tankless, with the price in front of you first.
Water quality matters in old plumbing too. Hardness minerals wear on pipes, fixtures, and every appliance that touches water, and you can see it in the scale on your shower doors.
- What blocks an old chimney: a bird nest, a couple of fallen bricks, decades of debris
- If your water leaves deposits or does not taste right, ask about water treatment while we are at your house
- We will tell you what is worth treating for and what is hype

Why Mt. Lebanon neighbors choose Wahl
The trickiest part of working on Mt. Lebanon houses is the part you cannot see from the curb. These homes were framed, vented, and ducted decades before today's high-efficiency equipment existed, so the new gear rarely fits the old infrastructure without some real know-how.
That is exactly the problem we have spent 46 years solving, and a 1920s house is no place for a company that only knows new construction to figure it out for the first time. We may not have seen your exact house, but we have seen one just like it.
How you do one thing is how you do everything, and that is the standard we hold every technician to. Your neighbors already trust us with their homes, call (412) 276-9245 and see for yourself.

Questions, answered
Do you offer emergency HVAC and plumbing service in Mt. Lebanon?
Yes. We run 24/7 emergency service across Mt. Lebanon and the South Hills. If the furnace quits on the coldest night of the year or a pipe lets go on a Sunday, call (412) 276-9245 and a real person will get you taken care of.
Can you work on the older systems common in Mt. Lebanon homes?
That is the work we know best. Steam and hot water boilers, radiators, aging furnaces, galvanized water lines, cast iron stacks, terra-cotta sewer laterals, we see all of it here every week. Our licensed technicians and plumbers, including a master plumber on staff, will tell you honestly whether a repair or a replacement makes more sense, and why.
How does your pricing work?
Flat-rate and upfront. You get the full price before any work begins, so you can make the call without surprises on the bill. No hourly meter running, no guessing.
What heating and cooling brands do you install and service?
We are a Rheem Pro Partner, a Mitsubishi Diamond Elite dealer for ductless systems, and a Bosch cold-climate heat pump dealer. We picked those brands on purpose, and our technicians also repair and maintain all major brands. Whatever is in your basement or on your wall, we can take care of it.
Do you have a maintenance plan for Mt. Lebanon homeowners?
Yes. The Wahl Club membership includes seasonal tune-ups, priority service, and member pricing. On an older home, maintenance is what catches the small stuff, a filter choking airflow, a chimney vent going bad, a slow drain, before it turns into the big stuff. Ask about it when you call or on your next visit.
