Frequently Asked Questions - Our Storefront

What Are Your Hours?

As mentioned earlier, we’re available by phone 24 hours a day. When it comes to our office, however, there’s limited time to visit. During the week, our CSRs are available 7 AM to 4:30 PM. This gives you a few hours before the office opens to swing by. We’re also open on Saturday from 7:00 to 3:00. So feel free to stop by after breakfast! This is obviously easier if you live in places like marlton, Queenland, or Bristol.

What Equipment Do You Service in Prince George's County?

Over our 63 years in business, we’ve acquired a number of verticals. But rest easy. We’re not a jack-of-all-trades. We’re masters of all of them. In addition to furnaces and air conditioners, we also service fireplaces, water heaters, boilers, and heat pumps. Because we keep up with the times, ductless systems are another thing in our wheelhouse. Our newest addition? Generator repair and installation.

What's Your Preferred Brand?

While we service all major HVAC brands—including Trane and Lennox—we only install certain ones. The equipment from these manufacturers has proved itself to us over the last 63 years. For air conditioners, we prefer to install Carrier. But we’re also big supporters of Goodman and American Standard. When it comes to generators, we're a supplier of Generac.

How Much Does It Cost for You to Come Out?

There’s a lot more to repairing a ac than the diagnosis. We also need to put gas in our trucks and pay our employees. Stocking parts also adds to that overhead. Then, there’s the cost of maintaining our office in Upper Marlboro. To help support these costs and continue providing superior service, we charge a dispatch fee of $79. This can be rolled into the cost of your repair or replacement.

Do You Offer Financing?

We do! At Belair, we know a new water heater or replacement AC unit are large expenses. They’re also not something considered when budget planning. You can apply for financing through either Synchrony or Wells Fargo. Depending on the time of year, these vendors offer promotional rates. Most approvals are processed instantly!

What Payment Methods Do You Take at This Location?

We want the process of paying for your ac or heat pump repair as hassle-free as possible. This is a big part of why we've been serving Crofton and Annapolis for so long. For that reason, we accept a number of payment methods. These (of course) include cash and check. But we also accept both VISA and MasterCard.

What Cities Do You Service?

Our HVAC and water heater company proudly services all of Prince George's County. But we have the most customers in Bowie, Crofton, and Annapolis. For a better idea of where we service, check out the list of cities in our footer.

Do you offer free quotes on ac and heat pump installation?

Your water heater is over ten-years old and starting to show its age. Maybe you moved into a new home knowing it needed its furnace replaced. Whatever the reason, it’s time to get quotes. And, at Belair, we want every customer to make an informed decision. So, we don’t charge a dispatch fee on new system quotes. Just call 301.249.0300 to book a quote. We also offer price-matching for apple-to-apple quotes in Upper Marlboro and Annapolis.

What’s the Best Way to Protect My AC in Prince George's County?

It’s getting your yearly tune-ups. There’s nothing else that comes close. During these visits, our HVAC expert will take a look at your system. They will check safety controls, verify thermostat operation, and clean the unit. Tests will also be conducted to uncover any hidden issues. Once these steps are complete, you can approach the upcoming season with confidence.

Are your HVAC technicians licensed and insured?

Yes. All of our HVAC technicians are fully licensed, bonded, and insured to work in Maryland. The same is true of all of our Bowie plumbers. We believe in doing the job right. That starts with sending professionals who meet all local and state requirements. You can feel confident knowing your home is in experienced, qualified hands.

What safety protocols do you follow during service calls?

Safety is always a top priority for our team. It doesn't matter what part of Prince George's County you call home. We follow manufacturer guidelines, wear protective gear, and maintain clean workspaces. For plumbing and HVAC services inside your home, our technicians wear boot covers and lay down drop cloths. We’re also happy to accommodate any special requests you may have. Just let us know in advance.

What should I do to prepare for your visit?

There’s not much you need to do! But for ac or water heater services, we recommend clearing the area around your equipment. This makes it easier for our experts to access. If you have pets, we ask that you keep them secured during the visit. This is for our safety and theirs. You can trust our experts in Upper Marlboro and Annapolis to handle the rest.

How long will a service call take?

Most HVAC or plumbing service appointments take between 60 and 90 minutes. For large AC repairs, furnace replacements, or generator installations, it might be four to eight hours. Our team will always give you a time estimate upfront and keep you informed if anything changes. We respect your time and strive to work as efficiently as possible.

Do you offer warranties on your work?

Absolutely. We stand behind the quality of our air conditioner and Crofton services. Most jobs come with a workmanship warranty, and many of the products we install include manufacturer-backed guarantees as well. For more details, check out our guarantees page.

What can I do to keep my HVAC and comfort systems running?

Here are 10 simple things you can do as a homeowner to keep your HVAC, plumbing, and generator in great shape:

Change your air filters regularly – Replace filters every 1–3 months to help your furnace, AC, and heat pump breathe easier.
Keep outdoor units clear – Trim back shrubs and remove debris around your AC or heat pump condenser. This also helps with generator ventilation.
Test your generator monthly – Run it under load and listen for unusual noises. Use this time to also check HVAC filters or thermostat batteries.
Clean your fireplace glass – Prevent buildup and keep the flame looking great with regular cleaning.
Use your thermostat properly – Avoid quickly flipping your heat pump between heating and cooling modes. Gradual changes protect system performance.
Don’t block vents – Keep furniture, curtains, and rugs away from registers and returns. It helps airflow and system efficiency.
Watch for odd sounds or smells – Clicking, banging, or gas odors should be checked by a technician. Don’t ignore them.
Trim back vegetation – Allow at least 2 feet of clearance around outdoor HVAC and generator equipment.
Schedule regular maintenance – Yearly tune-ups for your HVAC, water heater, and generator catch small problems early.
Know where your shut-offs are – Learn how to safely turn off gas, water, or power in case of an emergency.
