Furnace Replacement in Alexandria, VA

Cracked heat exchanger, a control board no longer made, or a furnace that has needed three repairs in two winters. Those are the conversations that lead to furnace replacement in Alexandria. We size the new unit to the house rather than matching whatever was installed decades ago, confirm the flue and combustion air are correct for the new equipment, and set up the condensate drain properly. Old thermostat wiring gets checked too. Call us or use the quote form to book an assessment.

Why Alexandria homes end up needing this

My furnace is close to twenty years old and something breaks every winter Cumulative wear on inducer, board and igniter where replacement costs less than the next round of parts
The blower is loud and the whole house smells dusty when heat comes on Aging blower assembly plus duct leakage pulling crawlspace air into the supply
We added a room and the heating never kept up after that Load change the existing furnace and duct system were never sized for

What a Furnace Replacement Day Looks Like

We shut off gas and power, disconnect and haul out the old furnace, then set the new one on a level base and rebuild the connections. That includes the supply and return plenum, the gas piping, the venting, the condensate drain on condensing units and the thermostat wiring. Most single-furnace homes are done in a day. In older houses with ducts in vented crawlspaces we allow extra time, because the existing sheet metal and insulation often need repair before the new unit gets connected.

What We Check and Install

Before we quote anything we measure the house, not just the old nameplate. Room sizes, window area, insulation and duct condition all feed the BTU calculation, and plenty of replacements we do are a smaller unit than the one coming out. We inspect the flue, the combustion air path, the return duct sizing and the electrical supply. On installation day we set the blower speeds, check gas pressure and temperature rise, confirm safety controls operate, and walk you through the filter size and thermostat before we leave.

How We Decide Replacement Beats Repair

We look at age, the specific failure and what else is likely next. A cracked heat exchanger or a failed control on a furnace past fifteen years usually points to replacement. A bad igniter or pressure switch on a ten-year-old unit is a heating repair, and we will say so. Repeat breakdowns, rising repair spend, uneven heat and rooms that never catch up in damp shoulder-season weather also weigh in. You get both options in writing, and the decision stays yours.

Furnace Replacement in Alexandria — quick answers

Can I replace only the furnace and keep my AC?

Often yes, if the coil and refrigerant lines are in good shape and match the new blower. We check coil condition and airflow first, because a mismatched pairing can hurt cooling performance later.

Does my ductwork need work too?

Sometimes. In houses with ducts in vented crawlspaces we frequently find disconnected runs, crushed flex and torn insulation. We inspect and report on it, then repair what the new furnace needs to breathe.

How soon can you get to my Alexandria home?

Call us and we will give you the first available window rather than a vague promise. During July and August heat waves, AC repair calls stack up, so morning calls usually get same-day or next-day attention. Parking is tight in Old Town and some condo buildings need a service elevator reserved, so tell us about that when you book and we will plan the visit around it.

How it works

Step 1
Tell us the symptom
Call or fill in the form and describe what changed. Warm air, short cycling, a smell, water near the indoor unit. Details like that help us load the right parts before we leave.
Step 2
We diagnose the whole system
We check the thermostat, the indoor unit, the outdoor unit and the ductwork, including runs in crawlspaces where damp air and loose joints quietly cause weak airflow and long run times.
Step 3
You approve the fix
We explain what failed, what it takes to repair it, and what we would watch next season. Nothing gets replaced without your yes, and we clean up before we leave.

Why homeowners call us

Humidity is our home groundMuggy summers and damp shoulder seasons drive most of the calls we take. We look at moisture and airflow together, not the cooling number alone, because a clammy house often means a sizing or duct problem.
Crawlspace ducts get checkedOlder homes across the region run supply ducts through vented crawlspaces. Crushed flex, disconnected boots and soaked insulation show up constantly, and we get under the house to look instead of guessing from the register.
Heating and cooling bothSame crew for air conditioning repair in July and heating repair in January. We know how your furnace, heat pump and air handler share ducts and a blower, so one visit covers the whole system.
Plain talk on repair or replaceWhen a repair makes sense, we repair it. When a system is failing in ways that will keep costing you, we say so and explain why, then leave the decision with you and your timeline.
