Harrisburg Service From Our Central PA Team

Our shop is in Mt Pleasant Mills in Snyder County, and Harrisburg is a regular stop on our service schedule. You do not have to find a shop nearby or haul anything anywhere. We come to your home or building, diagnose the problem on site, and walk you through your options before any work starts. For planned projects like a system replacement or a new ductless system, we start with a free consultation so you can compare equipment and costs without pressure.  

Heat Pumps Set Up for a Central PA Winter

A heat pump should keep your home comfortable in January, not only in October. When yours starts blowing lukewarm air, short-cycling, or running nonstop, we track down the cause, whether that is a refrigerant problem, a failing defrost control, or an outdoor unit that needs service.

We service and install electric and ductless heat pumps. As a Mitsubishi Electric Elite Diamond Contractor and Bryant dealer, we install equipment we know well and can support for years. If your system is showing its age, read how we handle electric heat pump repair and installation, and book a tune-up before the first hard freeze so a small problem does not turn into a no-heat call.

Furnace, Boiler, and Radiant Heat Repair Before Cold Weather Hits

A furnace that will not ignite or a boiler that keeps locking out is a problem you want solved this week, not next month. Our technicians repair and maintain gas and propane furnaces, oil boilers, and radiant heating systems. On a furnace visit, we check gas pressure, clean and inspect the heat exchanger, and replace worn parts so the system runs safely through the season.

If your home heats with radiators, we provide oil boiler service and repair, including cleaning and preventive maintenance ahead of winter. If your furnace is near the end of its life, we will tell you whether a repair makes sense or whether a new furnace installation will cost you less over the next several years.

Central Air and Ductless Cooling That Fits Your Home

Summer humidity can push an older air conditioner past its limit. We repair and replace central air systems, and when a home has no ductwork or one room never cools, a ductless mini-split is often the cleaner fix. Mini-splits suit finished attics, additions, rowhomes, and radiator-heated houses, because they deliver cooling (and heating, in heat pump models) without new ducts.

If your AC stops cooling, schedule air conditioning repair and we will explain what failed and what the fix costs before we start. For a new system, we size and install central air or ductless mini-splits based on your home, not a rule of thumb.

What Harrisburg-Area Customers Can Count On

We are members of UA Local 520, the Harrisburg-area union of plumbers, pipefitters, and HVACR technicians.

MGM Mechanical did a great job installing our mini split units (Harrisburg). They were very responsive and quick to fit us into their schedule for both the estimate and install. The installers were very professional and knowledgeable with our project. We are very pleased with our units and have noticed the difference already.

Serving Harrisburg Neighborhoods and Nearby Communities

We work throughout the city, from Midtown, Uptown, and Shipoke to Allison Hill, Bellevue Park, and Riverside. Outside city limits, we serve homes and businesses in Susquehanna Township, Lower Paxton Township (including Linglestown), Swatara Township, and Penbrook, and farther east in Middletown and Hershey. Across the Susquehanna, our Cumberland County service area covers the West Shore, and we also serve the rest of Dauphin County and neighboring Perry County. 

Credentials You Can Check Before You Call

Pennsylvania requires home improvement contractors to register with the Office of Attorney General. Our registration number is PA054276, and you can confirm it with the Attorney General’s Home Improvement Contractor search. We have served Central PA homes and businesses for 30+ years. We are a Mitsubishi Electric Elite Diamond Contractor and install Bryant heating and cooling equipment, so the systems we put in are backed by manufacturers we work with every day.

Harrisburg HVAC Questions, Answered

Yes, inside city limits. The City of Harrisburg Bureau of Codes requires a permit for mechanical installations such as a new furnace, and for any work over $1,000, and it handles the inspections. When we take on a replacement, we handle the permit application as part of the job. If you live in a surrounding township, your township’s code office issues the permit instead, and we plan the schedule around its process.

Under Pennsylvania’s Uniform Construction Code, the City must act on residential permit applications within 15 business days, or 5 business days when a licensed design professional has stamped the plans. Commercial applications can take up to 30 business days. Projects in a historic district can take longer if they need historic review. We build that time into your installation date so there are no surprises.

The City allows emergency repair or replacement of equipment before a permit is issued, as long as the permit application reaches the building code official within 3 business days of the work. That means you are not left without heat while paperwork moves through City Hall. We file that application for you as part of the job.

Yes. Ductless mini-split heat pumps mount on a wall or ceiling and connect to an outdoor unit through a small line set, so they do not need ductwork. Many homeowners keep their boiler for the coldest weather and use ductless heat pumps for cooling and mild-weather heating. We look at your home and recommend how many indoor units you need and where they should go.

Established customers can call (717) 543-3034 any time for urgent heating or cooling problems. If you are a new customer, call during office hours, Monday to Friday from 7:30am to 4:30pm, and we will get you on the schedule as quickly as we can.

Whether your heat pump needs a pre-winter tune-up, your furnace will not start, or you are ready to compare replacement options, you will get a clear diagnosis and a price before any work begins. Call to schedule service, or book a free consultation for a new system.
