Furnace Replacement Services in Northern Virginia

Being at the mercy of our icy winter nights is simply not an option, and your comfort is at stake when your furnace fails to meet your needs. That’s why the team at HVAC Unlimited offers top-of-the-line heating and cooling replacement services to bring you the comfort you need! Backed by products from industry-leading manufacturers and our world-class HVAC specialists, we can guarantee your furnace will fit your home like a warm, well-sized glove!

Our team offers all three of the powerhouse furnace system for your home. These are:

  • Gas furnaces. Quiet and clean, gas furnaces provide an excellent heating option with plenty of power. They do require a gas setup, which means they aren’t available for certain locations, and gas can be slightly variable in cost. But the investment is well worth the sheer quality of warmth!
  • Oil furnaces. The highest BTUs (British Thermal Units) per unit of fuel out of any furnace system! Oil furnaces are dependable, strong, and require less overall maintenance than other systems. The initial installation is a bit higher than electric, however, and some find oil prices unpalatable.
  • Electric furnaces. Cost effective, dependable, and quick to install, electric furnaces are featured in the vast majority of US homes. These furnaces are also safe (no combustible fuel sources), and use a reliable amount of energy each month for easy planning.

Not sure which furnace type suits you and your home’s needs best? No worries! Our experts can help—contact us today.

Signs You Need Furnace Replacement

Many prefer to opt for HVAC repairs before replacing. And in a lot of situations, our heating and cooling experts agree! But, there are a few occasions and issues where replacement is simply smarter, faster, less stressful for the homeowner, and cheaper overall. Wondering when to replace? Use these guidelines for a general idea:

  • When your furnace is too old. On average, a furnace should serve your home well for roughly ten to fifteen years. Past that point, it will begin to drastically lose efficiency, and will almost definitely need to be repaired much more frequently.
  • When your home’s heating is uneven. Problems with cold spots in your home? You might simply have an air flow issue; an easy fix with professional furnace repair. But if there is a deeper issue, replacement may be your best bet.
  • When your heating costs are too high. Monthly bill spiking up by ten to fifteen percent? Even more? If that’s the case, you’re going to save a lot of cash and stress by replacing!
  • When you need repairs too often. Once every few years? Not awful. Once a year? Unacceptable! A single repair may be cheaper than a replacement, but when you need two, three, or even four repair services within a few years, you might as well replace. We guarantee it’d be cheaper and far less frustrating.
