Sterling Gas Furnace Repair & Replacement
Quality Care for Your HVAC System in Maryland & Northern Virginia
Minimizing utility costs is a top priority for any homeowner, and for many, that means investing in a gas furnace. Systems powered by natural gas are efficient, powerful, and reliable heaters that will keep your home warm for years to come. At Donmar Heating, Cooling & Plumbing, we are proud to offer gas furnace repair and replacement as part of our comprehensive HVAC services offered throughout Virginia and Maryland.
Our New Installation Process
Every home has unique heating needs, and we are committed to finding a furnace that will meet those needs. Even when replacing an existing system, we will never just give you a gas furnace that is the same size as your old one. After all, it may have been improperly sized in the first place, or your home’s heating load may have changed. Instead, we will perform a full heat loss calculation, accounting for square footage, insulation, and other factors, to assess your home’s heating needs precisely.
Once we have a properly sized system, our installation experts will work diligently to get you your replacement as quickly as possible. As a Carrier Factory Authorized Dealer, we are experts on the manufacturer’s standards, and we see those standards as our absolute minimum requirements. We will do everything in our power to make sure any system we install is well-positioned to heat your home for years to come.
You may want to consider purchasing and installing a new gas furnace if you:
- Have an old furnace that is on its last legs
- Are interested in an energy-efficient upgrade for your home
- Are constructing a new home, and need a whole heating system for it
