Heating Challenges Unique to Northern Virginia
Heating a home in Northern Virginia isn’t the same as heating a home anywhere else. Our winters bring weeks of below-freezing nights, sudden swings between mild days and harsh cold snaps, and damp conditions that strain equipment. For homeowners, that means your system choice — and how you maintain it — matters more here than in many other regions.
What the Weather Means for You
Furnaces and boilers in this area often run almost nonstop in January and February. Without annual tune-ups, the constant workload shortens system life and increases the risk of breakdowns when you need heat most.
Utility Realities
In Fairfax and Arlington, most homes rely on natural gas from Dominion Energy, while propane is common in rural Loudoun and Prince William. If you’re moving from oil to gas, or considering a switch to propane, it’s important to understand how fuel type affects your heating costs and maintenance needs.
Housing Considerations
Older Alexandria rowhomes may have aging ductwork or rely on boilers, while Fairfax colonials and Loudoun townhomes often need high-efficiency furnaces or supplemental ductless systems to cover additions. Knowing your home’s limitations helps prevent uneven heating and high bills.
Why It Matters
Because we’ve worked on every type of home and heating system across the region since 2006, we can guide you to the right decisions — whether that’s upgrading ducts in an older property, switching to a more affordable fuel source, or installing a system built for long, heavy winters.
Frequently Asked Questions About Heating Services
When it comes to providing perfect heating solutions for our customers, we’ve learned a thing or two over our 12+ years in the HVAC business. Here are some of the most common questions we receive from homeowners just like you.
Why is my house not heating up?
If your house isn’t heating properly, the issue could be as simple as a dirty air filter or as complex as the need for heating replacement. Whatever the cause, the experts at HVAC & Plumbing Unlimited will get to the bottom of it quickly and get your heat in working order fast!
What to do if my heat is not working?

The team at HVAC & Plumbing Unlimited is dedicated to fast, efficient troubleshooting when it comes to your home’s heat—We’ll uncover the problem and provide you with suitable options for heating repair or system replacement.
How often should you replace your heating system?
The average furnace lasts approximately 20 years, but that number can increase or decrease depending on the level of care you invest in system maintenance. If you’re looking for a team to perform quality heating maintenance to extend the service life of your system, or if it’s time to replace your furnace or boiler, give HVAC & Plumbing Unlimited a call and we’ll make the process simple.
What do you call a person who fixes heating & air conditioning systems?
While we think of our team members as family, we understand that not every homeowner is privy to HVAC industry language. The technical term for heating and cooling system experts would be HVAC technicians. At HVAC & Plumbing Unlimited, our technicians are factory-trained and certified for every job, with an average experience of 12+ years in the industry.
How often should a heating system be serviced?
You should plan to invest in heating system maintenance at least once per year. While this may seem like an unnecessary task when your system is operating as it should, regular maintenance will serve to extend the service life of your system and alert you to any small issues before they become larger, more costly problems.
