Is Your Furnace on the Fritz?

Installing a new heating system is a significant investment, and choosing the right one makes all the difference in efficiency, comfort, and cost savings. Our experts take the time to evaluate your home's layout, insulation, and energy requirements before recommending a furnace, heat pump, or boiler that will deliver consistent heat without driving up your utility bills.

We manage the entire installation process from start to finish. That includes removing your old unit, preparing the installation site, and performing final testing to ensure peak performance. With financing options available, our heating installations in Annandale are accessible to homeowners on all budgets.

Upgrading your heating system isn't just about comfort, it's also an opportunity to save money. According to Globe Newswire, energy-efficient systems accounted for roughly 25% of all HVAC installations in North America in 2024, underscoring the growing demand for cost-saving upgrades. Modern furnaces and heat pumps are designed to deliver better performance using less energy. We offer high-efficiency models with ENERGY STAR® certification and help homeowners qualify for rebates when applicable.

In addition to replacing old systems, we also install smart thermostats and zoning controls that give you greater command over your home's climate. By integrating smart solutions, you'll enjoy reduced energy waste, better temperature balance, and noticeable savings on your monthly heating bills.

Cold weather often brings stale, dry air indoors. Poor air quality can irritate allergies, dry out your skin, and lead to respiratory discomfort. That's why our heating services in Annandale include indoor air quality enhancements that work in tandem with your HVAC system.

We offer whole-home humidifiers, air filtration units, and purifiers that target dust, pollen, mold spores, and airborne bacteria. With the right setup, you'll breathe easier and enjoy a more comfortable indoor environment-especially during long winter months when homes stay sealed tight.

If you're heating a garage, guest suite, addition, or any space without ducts, ductless mini-split systems are a great solution. These units are compact, quiet, and energy efficient. Plus, they allow for zoned heating, so you can control the temperature in each area independently.

We'll help you select the right model, install it properly, and keep it performing at its best with regular maintenance. It's a convenient way to add heat where you need it-without a costly renovation.
