HVAC & PLUMBING SERVICES

Trusted HVAC & Plumbing Services Across Maryland, Virginia & D.C.

JDL HVAC & Plumbing Services has been the go-to heating, cooling, and plumbing company for DMV homeowners since 2012. We're based in Laurel, MD — not a national call center — and every technician on our team is background-checked, NATE-certified, and trained on the latest equipment from Carrier, Lennox, Trane, Goodman, Rheem, and York.

We've completed thousands of jobs across Prince George's County, Howard County, Anne Arundel County, Montgomery County, Northern Virginia, and Washington D.C. — everything from emergency furnace repairs at 2 AM to full HVAC system replacements in historic Georgetown rowhouses. Our 683+ Google reviews at a 4.8-star rating aren't bought or incentivized — they're earned one job at a time.

Heating Services — Furnace Repair, Heat Pumps & Installation

Maryland and Virginia winters are unpredictable. One week it's 55 degrees, the next we're dealing with single digits and wind chill advisories. When your furnace stops producing heat or your heat pump can't keep up, our technicians respond with true 24/7 emergency service — we typically arrive within 2 hours, even on nights, weekends, and holidays.

What sets our heating service apart:

• Every furnace repair includes a complimentary carbon monoxide safety check — no extra charge
• We carry common parts on our trucks (ignitors, capacitors, blower motors, gas valves) so most repairs are completed in a single visit
• We service gas furnaces, electric furnaces, heat pumps, and dual-fuel systems from every major manufacturer
• For system replacements, we perform a Manual J load calculation to size your new equipment properly — not a rough guess based on square footage
• We're one of the few DMV contractors with a National Balancing Council Certification, which means we can properly balance airflow throughout your home so every room heats evenly

Air Conditioning — AC Repair, Installation & Maintenance

DMV summers bring 95-degree days with humidity that makes it feel like 105. A failing AC system isn't just uncomfortable — it can be dangerous for children, elderly family members, and pets. Our EPA-certified technicians specialize in diagnosing and repairing every type of cooling system, from 30-year-old central air units to brand-new ductless mini-splits.

What you can expect from our AC service:

• Same-day AC repair if you call before noon — guaranteed
• Upfront, flat-rate pricing approved before we start any work — no hourly billing, no surprise charges
• We diagnose the actual root cause, not just the symptom. If your AC is freezing up, we'll tell you whether it's a refrigerant leak, a dirty evaporator coil, or a blower motor issue — and explain the cost difference between each fix
• For new installations, we help you navigate SEER2 efficiency ratings, utility rebates, and financing options so you get the best system for your budget
• We install central air, ductless mini-splits, and heat pump systems — and we'll honestly tell you which type makes the most sense for your home's layout and ductwork

Plumbing Services — Drain Cleaning, Water Heaters & Emergency Repair

Our licensed master plumbers handle everything from routine drain cleaning to full sewer line replacements. We use professional-grade equipment that most plumbing companies don't invest in — including sewer camera inspection systems and hydro-jetting machines that clear even the most stubborn blockages without damaging your pipes.

Plumbing services we provide:

• Drain cleaning — Kitchen sinks, bathroom drains, main sewer lines, and floor drains. We use camera inspections to show you exactly what's causing the clog before we clear it
• Water heater repair & installation — Tank and tankless systems from Rheem, Bradford White, A.O. Smith, Navien, and Rinnai. If your water heater is leaking, producing rusty water, or just not keeping up, we'll diagnose the issue and give you an honest repair-vs-replace recommendation
• Emergency plumbing — Burst pipes, sewage backups, and flooding don't wait until business hours. We dispatch emergency plumbers 24/7 and typically arrive within 2 hours
• Bathroom & kitchen plumbing — Fixture installation, pipe replacement, leak detection, and full renovation plumbing
• Sewer line service — Camera inspections, hydro-jetting, and sewer line repair or replacement for older cast iron and clay pipes common in DMV homes built before 1980
