It’s the first cold morning of winter, and the furnace won’t light. The heat pump ran all afternoon, but the house still doesn’t feel warm. We receive these calls from frustrated Northern Virginia homeowners every year, and we’re here to help.
John C. Flood has been working in the DMV for more than 120 years. Our licensed technicians repair, install, replace, and offer annual maintenance on all major heating systems found in Virginia homes, including furnaces, heat pumps, boilers, and zoning systems.
Every visit starts the same way. A technician will assess your home’s system, explain what is happening in plain terms, and recommend options before the work begins. We offer flat-rate pricing seven days a week.
A heating system may need different levels of service at different points in its life, and our team handles it all.
We handle furnace repair, heat pump repair, and boiler repair throughout Northern Virginia. A visit begins with an in-home assessment of the system and a conversation about what you’ve been noticing. Your technician then explains what failed and why, lays out your options with a clear recommendation, and gives you the price before any work starts.
Our call center is available 24/7, and we schedule same-day appointments when available. If you call overnight, we will schedule you for the earliest availability the next day.
A heating system that was installed correctly will outlast one installed quickly. John C. Flood technicians install furnaces, heat pumps, and boilers, and we’ll always recommend what we think is the best fit for your home’s needs.
Replacing and installing a heating system may not be as simple as matching what was there before. Your technician will assess the square footage, the layout, the condition of the ductwork or piping, the insulation, and how your household actually uses heat. Once the equipment is in place, we test the heating system and walk you through how to run it.

The best time to service a heating system is before there is an emergency, which means early fall for Virginia homeowners. An annual visit catches worn components before they have broken down, keeping the system running the way it should.
A maintenance appointment covers the things that quietly degrade over a season. Your technician will:
Our Service Partner Program helps you plan seasonal visits and includes priority scheduling if an emergency comes up.
Northern Virginia homes are heated differently depending on when and where they were built. A historic 1920s home in Old Town Alexandria has completely different heating needs than a modern build in Loudoun County. That is why our team services all of the system types common in this region.
You don’t need to diagnose the problem yourself before giving us a call. Describing what you’re experiencing is plenty for our team to go on, and a technician will quickly determine whether it’s a simple adjustment or requires a larger repair. Keep an eye out for these common signs:
Experiencing any of these issues doesn’t necessarily mean your system needs complete replacement. Often it indicates the system is working harder than required, which is much easier to resolve when caught early. You can book a visit online or call our team anytime to discuss what you’re seeing.
Heating repairs rarely come at a convenient time, and replacing a system is a significant investment. We aim to make necessary heating services manageable for your budget.

Age is often the first indicator. ENERGY STAR suggests considering replacement once a heat pump passes 10 years and once a furnace or boiler passes 15. Key factors include whether this is an isolated failure or part of an ongoing pattern, whether a major component like a heat exchanger or compressor has failed, and whether your home has persistent comfort issues during normal operation. A repair is frequently the best path forward, and we will always give you a straightforward recommendation after evaluating your system in person.
In most cases, yes. Under the Virginia Residential Code, replacing a gas-fired appliance like a furnace or boiler requires a permit even for a direct replacement. Electric heat pump changeouts may be exempt depending on county regulations.
Not always, but it is an important consideration. In a typical split system, the furnace houses the blower, and the indoor evaporator coil sits directly above it, physically connecting the two units. If your air conditioner is a similar age, replacing both at the same time often reduces overall installation labor and ensures peak efficiency. Your technician can evaluate whether your existing coil can remain, and flexible financing options are available to help manage the cost of full system upgrades.
Most standard replacements are completed in a single day. Our technicians remove the old equipment, install and commission the new system, and thoroughly test it before leaving so your home stays warm overnight. Projects requiring ductwork modifications, new venting, or system conversions may take longer, and your technician will clearly outline the timeline during your estimate.
