Why Perform Regular Heating Maintenance?

While it may seem like a hassle to schedule regular maintenance for your heating system, it can actually save you time and money in the long run. When you have a properly working heating system, it can be extremely beneficial.

Some of the benefits of a properly maintained and functioning heating system include:

  • Reducing the amount you pay for monthly utility bills
  • Reducing the problems or future problems
  • Extending the life of your current system
  • Higher quality, more breathable air

Heating Sales & Installation

From boilers and furnaces to heat pumps, there is a dizzying array of heating systems available to homeowners today, and each comes in several different variations. We are prepared to help you select the best system for your home, whether it is an upflow furnace in the basement, an energy-efficient heat pump that will pull double duty, or a gas boiler that will facilitate heat flow throughout your home.

Every home’s heating needs are different, and we acknowledge that difference at the start of each project. Before giving an estimate, we will perform a full heat loss calculation to assess exactly how much heating power your home requires. Once we have the results in hand, we will work with you to pick out a system that will meet those heating needs with no wasted power, which means more money stays in your pocket.

As a Carrier Factory Authorized Dealer, we are fully familiar with the manufacturer’s standards and know how to make sure every system we install meets or exceeds those standards. Our Virginia HVAC services team has a long history of customer satisfaction to prove that we take this commitment very seriously.

Heating Repairs & Emergency Repairs in Sterling

If your furnace refuses to start in the middle of January or your heat pump shuts down on a cold February day, there is no need to panic. Our Virginia and Maryland HVAC repair experts are available seven days a week from 7 a.m. to 10 p.m. to come to your home, resolve the issue, and keep your family safe.

We know that heating problems don’t respect your schedule. Because of this, we offer convenient business hours every day so you don’t ever have to worry about an extra charge for a weekend or evening visit.

Annual Heating System Maintenance Agreements

We believe the best approach to heating problems is prevention. With an annual maintenance agreement, we can come to your home at the start of the heating season and make sure your boiler, furnace, or heat pump is running properly. We’ll assess any small, emerging issues and fix them before they turn into major ones, saving you money down the road on expensive repairs. Moreover, our technicians will make small calibration adjustments to maximize fuel efficiency, which means you will see an immediate drop in your utility costs.

The Premier Professionals in the Heating Industry

Our Virginia and Maryland heating repair experts hold NATE certification, which is the HVAC industry’s premier certification for service professionals. NATE Certified contractors are trained to maintain and repair all makes and models of heating equipment, and they have the experience needed to analyze and resolve any problem. On top of that training, we use ongoing professional development seminars to keep our technicians abreast of the latest techniques and best practices.
