Furnace Maintenance in Maryland & the Greater DC Metro Area

Tune Up Your Furnace Before Winter

Should I Get My Furnace Inspected?

Furnaces, especially newer ones, are designed to last a long time — usually as long as 10 to 15 years. But even the most well-designed system might run into problems, especially when it’s been sitting idle for months at a time. To avoid any cold nights, it’s better to get the furnace checked before the winter season begins.

Regular furnace maintenance can help revive your system and ensure it runs at max efficiency. Your annual furnace inspection can also help prevent untimely breakdowns that can lead to costly repairs (in the middle of furnace season!). Before the air gets too cold this year, save money and call Michael Bonsby HVAC & Plumbing for your annual furnace maintenance visit.

Be proactive this fall and call 240-342-6910 or contact us online today!

Maintenance Agreements

If you want to control costs in your home, you should strongly consider signing up for one of our standard maintenance agreements. Regular maintenance is critical to all forms of HVAC in your home, both to keep standard operating costs low and to prevent early replacement or constant or higher-value repairs. With one of our maintenance agreements in place, you won’t have to think much about maintenance at all. We offer multiple plans to better meet the varying needs of our customers.

Biannual HVAC Maintenance Agreement

Our biannual HVAC maintenance agreement will ensure that your units get the two visits per year they ought to have, allowing us to rapidly identify problems and resolve them while they’re still inexpensive to resolve — and also letting us tune your systems for higher performance and efficiency throughout the busy seasons of the year.

Monthly HVAC Services Contract

With our monthly HVAC service contract, we inspect refrigerant lines, clear away dirt and other buildup from sensitive components, replace or clean air filters as is appropriate for your HVAC model, and regularly assess your system for safety and function.

A monthly contract greatly reduces the risk of having more costly repairs pop up and can limit your risk of breakdowns and unexpected outages to a fraction of what that risk might otherwise be. This is a strong option if HVAC system downtime is completely unacceptable to you or if you want to always be at maximum comfort throughout the year.
