Heating

Heating installation, repair, and maintenance for residential and commercial properties across the DMV. Our licensed technicians service furnaces, boilers, heat pumps, and ductwork, with 24/7 emergency response when temperatures drop.

About the service

Heating systems in the DC area work hard from October through April, and they have a habit of failing on the coldest nights. Tim Whistler Plumbing services every type of residential and commercial heating system across Maryland, Virginia, and Washington DC: gas and oil furnaces, boilers, heat pumps, radiant systems, and steam. We install, repair, maintain, and replace, with 24/7 response when the heat goes out.

If your furnace is short-cycling, your boiler is making strange noises, your radiators aren't getting hot evenly, or your heating bill jumped this winter, we'll diagnose the real problem and give you honest options. Sometimes the right answer is a repair, sometimes it's a replacement. We'll tell you which it is for your specific system and home.

An undersized heater short-cycles and dies young. An oversized one wastes money for its entire life. We size, install, and tune every system properly so it heats your space efficiently and lasts as long as it should.

We work with all major brands and every fuel type used in the DMV, including gas, oil, electric, and heat pump systems. Because our team is licensed across plumbing, gas, and electrical, we coordinate gas line, venting, and circuit work in house instead of waiting on subs. Older homes in Takoma Park, Mount Pleasant, Old Town Alexandria, and the Frederick historic district often have radiator or steam systems that need specialized service, and we know how to keep them running.

FAQs

Common Questions You May Have

These are the most common questions people ask our professional plumbers and electricians.
Do we install tank and tankless water heaters?

Yes. We install, replace, and service traditional tank water heaters and ENERGY STAR rated tankless gas systems for homes and businesses across Washington DC, Maryland, and Northern Virginia. We handle the gas, water, and venting work in-house since our team is licensed across plumbing, gas, and HVAC. Tankless conversions often qualify for utility rebates, and we'll walk you through which option makes sense for your home.

Do you install EV chargers and handle electrical panel upgrades?

Yes. Our licensed electricians install Level 2 EV chargers and handle full electrical panel upgrades (100A, 200A, and 400A) across the DMV. Older homes often need a panel upgrade to support modern loads like an EV charger, heat pump, or solar system. Every project is permitted, inspected, and brought to current code. Call 1-866-477-6190 for a panel evaluation.

Do you offer free estimates?

Yes. We provide free estimates for most installation and replacement projects, including water heaters, boilers, AC units, panel upgrades, gas line work, and full system installations. For diagnostic work on existing equipment (like an AC that isn't cooling), there may be a small service call fee that's credited toward the repair if you move forward. Call 1-866-477-6190 to schedule.

Do you offer 24/7 emergency plumbing, gas, HVAC, and electrical service?

Yes. Tim Whistler Plumbing offers true 24/7 emergency response for plumbing, gas, HVAC, and electrical issues across the DMV.
