Belair Knows Mitchellville

Since 1962, Belair Engineering and Service Company, Inc. has provided thousands of Mitchellville homeowners with the quality home services they can rely on. Whether they need help with their HVAC system or plumbing, we are the trustworthy professionals who get the job done.

Our extensive time here has allowed us to grow with the town and truly get to know every neighborhood from Woodmore to Lake Arbor. This is especially true for our owner, Debbie Risher, who always admired her family’s commitment to improving people’s home comfort.

Debbie began helping out at Belair after college and later took on the role of second-generation owner. Her love for HVAC grew over time until she eventually became the county’s first woman president of the Air Conditioning Contractors of America. In addition to this incredible honor, our business has also won Prince George’s County “Small Business of the Year” and the Capital Gazette’s “Best HVAC Contractor Award.”

Why Mitchellville Homeowners Choose Belair

Mitchellville has dozens of HVAC companies to choose from, but not all meet our standards. Find out why homeowners have trusted our professionals for decades:

  • In business since 1962, now second-generation. A ten-year parts warranty is only as good as the company standing behind it. We have been answering the phone in this county for more than 60 years, and the family running Belair today grew up in the business.
  • Two guarantees, both in writing. Our 100% satisfaction guarantee covers the work we do. Our no-lemon equipment guarantee covers the hardware, so if a new system turns out to be a bad unit, replacing it becomes our problem rather than yours.
  • Flat-rate pricing, quoted before we start. You get the price for the repair up front instead of an hourly meter that keeps running while a technician hunts for the fault. Financing is available on new systems if you would rather spread the cost.
  • Background-checked technicians. Every person we send to your door has been screened. You should not have to wonder about who is walking into your house.
  • Award-winning work. Prince George's County named Belair its Small Business of the Year, and the Capital Gazette named us Best HVAC Contractor. Manufacturers have taken notice too: Carrier, Goodman, and American Standard have each recognized our installation work.
  • Woman-owned and managed. Debbie Risher runs the company her family started, and she was the first woman to serve as president of the local Air Conditioning Contractors of America chapter.

The Answer to All Your Heating Problems

Mitchellville calls us about heat more than anything else. A furnace that will not light on the first cold night. A system that runs and runs without warming the house. A burner that fires up and shuts off every few minutes. Here is how we handle each part of it.

Furnace Repair

Most Mitchellville furnace calls come down to a short list of parts. We diagnose first, quote second, and fix third. If a furnace is unsafe to run, we will say so plainly and shut it down rather than patch it and leave.

Fix My Furnace

Furnace Replacement

At some point a repair stops making sense. That is why it is best to replace Mitchellville furnaces over 15 years old when repairs are more than a third of the replacement cost. We give you both numbers and let you make the call.

Get a New Furnace

Furnace Maintenance

A tune-up in the fall catches the parts that fail in January. It also keeps most manufacturer warranties intact, since nearly all of them require documented annual service.

Keep Warm All Winter

Boiler Service

Some older Mitchellville homes still heat with a boiler feeding radiators or baseboard. Boilers are a different trade from forced air, and plenty of HVAC companies no longer touch them. We still do.

Service My Boiler

Heat Pump Service in Mitchellville

A heat pump both heats and cools, which is why it gets its own special section. It moves heat instead of burning fuel to make it, pulling warmth out of the outdoor air in winter and pushing it back out in summer. That makes it efficient. It also means a single failure takes out your heating and your air conditioning at the same time.

Heat Pump Repair

When a heat pump struggles, you may notice a longer run time or an electric bill that climbed with no change in Mitchellville’s weather. We find the fault, show you what we found, and price the repair before we touch it.

Restore My Heat Pump

Heat Pump Replacement

The lifespan for most heat pumps in this climate is 10 to 15 years. If yours is near that mark and beyond repair, we will tell you.

Replace My Heat Pump

Heat Pump Installation

Sizing matters more on a heat pump than on almost anything else we install. That is why we run a load calculation on your home before quoting. Then, we give you options at more than one price and efficiency level so you can compare.

Install My Heat Pump

Heat Pump Maintenance

A heat pump works year-round, so it racks up close to twice the run hours of a furnace or an air conditioner on its own. That is why it is important to service it in both spring and fall when Mitchellville is between its more extreme weather seasons.

Service My Heat Pump

Here for All Your Cooling Problems

Summers in Prince George's County bring heat and heavy humidity together. A system that drops the temperature without pulling moisture out of the air still leaves a house feeling clammy, so we size and service for both.

AC Repair

The call we get most in July is an air conditioner that runs but will not cool. We check the cheap things first, so you are not paying for a major repair when a filter and a coil cleaning would have solved it.

Regain Your Cool

New Air Conditioners

A replacement quote from us starts with a load calculation, not a guess based on the size of the current AC unit. That matters in Mitchellville, where additions mean the house is often larger than whatever the original system was sized to cover.

Get an AC Quote

AC Maintenance

Spring service is inexpensive insurance against a summer breakdown. We clean parts, tighten connections, and test everything to ensure your AC is ready for the Mitchellville heat.

Prepare for Summer

Ductless Mini-Splits

Not every room can be reached with ductwork. A ductless mini-split puts a small indoor unit in the room you want conditioned, then runs a slim refrigerant line to a compressor outside. You get heating and cooling without opening walls for ducts.

Go Ductless

Sized Right for Mitchellville's Bigger Homes

Mitchellville houses tend to be large, and many have grown since they were originally built. That produces a familiar set of complaints. Bedrooms over the garage that never cool down. A finished basement that stays cold no matter the setting. A second floor running several degrees warmer than the first.

The fix is rarely a bigger system. More often it is a system sized correctly for the house as it stands now, with the ductwork balanced. We add zoning where it makes sense so upstairs and downstairs can call for air separately.

That work begins at the estimate. A proper quote includes a load calculation accounting for square footage, insulation, window area, and which way the house faces. It lists the model numbers and efficiency ratings of what is being proposed, so you can look them up yourself. And it gives you more than one option, letting you weigh a mid-range system against a high-efficiency one with real figures in front of you. A quote that does none of that is a guess wearing a letterhead.

More Than an HVAC Company

Belair started as a heating and cooling company but did not stay one. If something in your house moves air, water, or gas, there is a good chance we work on it.

Generator Installation and Service

Storms knock the power out in this part of Prince George's County. A standby generator is the difference between a few dark hours and a weekend of cold showers and spoiled groceries. We can size, install, and service it to be ready for the next storm.

Keep Your Power

Plumbing, Water Heaters, and Sump Pumps

Our plumbers handle the everyday work from a running toilet to a leaking water line. We also service water heaters, which are a large share of the calls. For Mitchellville specifically, sump pumps are a popular way to keep water out of finished basements.

Go with the Flow

Indoor Air Quality and IAQ Testing

Mitchellville springs bring pollen, and summers bring humidity, both of which end up indoors. We can perform indoor air quality testing and install high-efficiency air filters for better breathing conditions. It is worth doing if someone at home has allergies or asthma that get noticeably worse inside.

Breathe Easy

Regular Maintenance Is a Great Investment

Maintenance is the cheapest thing we sell and the easiest thing to put off. Service it twice a year, spring for cooling and fall for heat. That keeps a system running near its rated efficiency and catches small failures before they turn into emergency calls. It also protects your warranty, since most manufacturers require documented annual service, and a denied claim on a compressor is an expensive way to learn that. Serviced systems tend to reach the top end of their expected lifespan instead of the bottom. Ask us about a maintenance agreement while we are out at your house.

Our Service Process

  1. You call, we schedule. You get an arrival window and the name of who is coming.
  2. We diagnose before we quote. The technician finds the actual fault and shows you what they found.
  3. You get a flat-rate price in writing. Nothing starts until you approve it.
  4. We do the work and clean up. On installations, we pull the county mechanical permit, meet the inspector, and fill out your warranty and rebate paperwork.
  5. We stand behind it. If the work is not right, call us, and we will come back.

Frequently Asked Questions

Which Mitchellville ZIP codes and neighborhoods do you serve?

Mitchellville covers 20716, 20717, 20720, and 20721, and we service every one of them. That includes Woodmore, Lake Arbor, Kingsford, Woodmore South, and the homes along the Enterprise Road corridor.

Are permits required for HVAC work in Mitchellville?

Yes, and Prince George's County is stricter about it than some neighboring jurisdictions. A mechanical permit is required to install, alter, replace, or remove a heating or cooling system. The county's local amendments go further and cover equipment-only replacements, which some other Maryland jurisdictions let pass without a permit. Whoever pulls the permit must hold a current Maryland HVACR Master license and be registered with the county's Department of Permitting, Inspections and Enforcement. We handle the permit and the inspection as part of the job.

Do you offer emergency HVAC service in Mitchellville?

Yes. Call the main number, and after hours you will reach our answering service, which pages the on-call technician. Someone calls you back with a time rather than leaving you waiting to find out. Ask about after-hours rates on that call so you know the cost before we send anyone out.

How much will HVAC service in Mitchellville cost?

Every home’s HVAC needs are different, so there is no one-size-fits-all price. The only way to know your service cost is to have one of our technicians run a diagnostic check and then quote you based on their findings. Once we begin working, you will be charged a flat-rate fee. As a general guide for this region, most common repairs land between $300 and $700, but can be more depending on the damage. Those are industry-typical ranges for the area, not a Belair price list. Call us, and we will give you the real number for your job before any work begins.

My Mitchellville home doesn't have ductwork. Can I still have heating and cooling installed?

Yes. A ductless mini-split system handles exactly this. A small indoor unit mounts on the wall or ceiling of each room you want conditioned. A slim refrigerant line runs out to a compressor outside, so nothing has to be torn open to make room for ducts. It is the standard answer for older homes built without ductwork, and for additions, sunrooms, and converted garages the existing ducts never reached.

Do you offer anything besides HVAC in Mitchellville?

Yes, quite a bit. We do plumbing, including water heaters and sump pumps. We install and service standby generators. We also handle indoor air quality with whole-house humidifiers, air purification systems, and indoor air quality testing. For most of what a house needs, you can call one number: 888.823.5247.

Can you help me install a generator in Mitchellville?

Yes. We size, install, and service standby generators. We will also walk you through the choice between a unit that backs up the entire house and one sized for the circuits you actually care about. The price difference between them is significant. Installation covers the electrical and gas connections and the county permit. We also service generators on a schedule, since one that never gets exercised often will likely not start when the power finally goes out.

Will Belair still be here if I need warranty work years from now?

Yes. That is a fair question for any contractor, and it is a big part of why Mitchellville homeowners call us. Belair has been in business since 1962 and is now run by the second generation of the same family. A ten-year parts warranty on a new system only means something if the company that installed it is still picking up the phone in year nine. We have been picking it up in Prince George's County for more than 60 years.
