AC Repair & Furnace Repair in Dundalk

Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.

AC Repair in Dundalk

A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. You get a clear price before any work starts, and if the system is old enough that replacement makes more sense, we'll show you both numbers.

  • Warm air coming from the vents
  • Condenser fan not spinning
  • Ice on the refrigerant lines or indoor coil
  • Condensate backing up around the air handler
AC repair costs and common fixes

Furnace Repair in Dundalk

Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.

  • Furnace clicks but never lights
  • Burners light, then shut off within seconds
  • Blower running but the air isn't warm
  • Loud banging, squealing, or grinding at startup

When to Call

Common Heating & Cooling Problems in Dundalk

HVAC trouble can appear without warning. If you're seeing any of these problems, call us today for prompt help.

AC Blowing Warm Air

When the AC runs but the house won't cool, the fault is almost always one specific component. We find it and fix it fast.

AC repair

Furnace Won't Stay On

If the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.

Furnace repair

Rising Bills, Weak Airflow

Weak airflow at the vents points to duct restrictions, a struggling blower, or high static pressure. A tune-up finds it before it kills the motor.

Maintenance & tune-ups

Old System, Repeat Repairs

We size replacements with a real load calculation, not a guess, so the new system delivers even temperatures and lower bills from day one.

System replacement

Dusty Air & Musty Smells

If some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.

Air duct cleaning

Rooms That Never Get Comfortable

We size and mount mini-splits cleanly, proper line sets, condensate handling, and a tidy exterior finish, so they work as good as they look.

Why Choose Us

The Dundalk HVAC Advantage

Same-Day Response

Most repair calls are diagnosed and fixed in a single visit because we stock the common parts, capacitors, contactors, igniters, motors, on every truck.

Skilled Professionals

Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.

No Upsell, Ever

We treat your budget like our own: fix what's fixable, replace what isn't, and size every new system to your home instead of the biggest thing on the truck.

Built to Last

A proper repair includes the details: static pressure check, capacitor test under load, combustion analysis on furnaces, and a clean condensate path that won't back up in August.

Local Experience That Makes a Difference

Our team goes beyond the quick patch. We know the failure patterns, duct issues, and code details common to local homes and businesses. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.

Our Customers Speak for Themselves

Rated 4.8/5 · 150+ reviews

"The furnace quit at 11 pm with the temperature dropping fast and a newborn in the house. They picked up immediately and walked me through the basics over the phone, then had a technician out first thing. Heat was back before noon. Absolute pros."

"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. The first winter's bills were noticeably lower, and we got cooling out of the same equipment. Best decision we made on this house."

ES
Elena S.
Dundalk, MD

"Another company quoted us a full system replacement. Dundalk HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. You remember honesty like that."

Our Promise

Built on Trust, Backed by Results

We do more than patch the symptom. We give you lasting comfort. Every visit is backed by our experience, honest recommendations, and thorough work you can count on.

Experienced Technicians

Real experience is a requirement, not a bonus. It means every technician understands sizing, airflow, and combustion, works clean and safe, and explains the work in plain language at a level most companies don't reach.

Right-Sized, Code-Compliant Work

We match every replacement to an actual load calculation rather than defaulting to whatever's on the truck. Installations get done to code: sealed duct connections, correct line sets, proper condensate handling, clean electrical work. Most installs are completed in a single day with minimal disruption.

Maintenance That Pays for Itself

A maintained system simply lasts longer, and we'd rather earn your trust than sell you a condenser early. Every maintenance visit is thorough and documented. For hard-working systems, a spring coil cleaning is the difference between year 10 and year 15. That's the Dundalk HVAC way.

Quick Answers

Your Questions, Answered

Most air conditioner repairs in Dundalk run between $150 and $650, depending on the part. Common fixes like capacitors, contactors, and fan motors sit at the lower end, while compressor and refrigerant work costs more. If the system is beyond economical repair, full replacement typically ranges from $5,000 to $12,000 installed depending on size and efficiency. We diagnose first and give you a clear, upfront quote before any work begins.
A good rule of thumb: if the system is under 10 years old and the fix is a component, capacitor, motor, igniter, sensor, repair usually makes sense. If the compressor or heat exchanger has failed, the unit is past 12 to 15 years old, or repairs are stacking up season after season, replacement is the smarter investment. Our technicians walk you through both numbers honestly so you can decide with real information.
We offer same-day and emergency HVAC service throughout the Dundalk area. Our trucks carry the most common parts, capacitors, contactors, igniters, flame sensors, and universal motors, so the majority of repairs are completed in a single visit. Even full system replacements are usually scheduled within days, not weeks.
For many Dundalk homes, yes. Modern heat pumps heat and cool from a single system, run far more efficiently than electric resistance heat, and current models perform well even in cold weather. They cost more upfront than a basic AC swap, which is why we run the numbers on your actual usage and utility rates before recommending one.
Yes. Our technicians work on all major residential and commercial brands and system types, central air conditioners, gas and electric furnaces, heat pumps, packaged units, and ductless mini-splits. We carry universal parts on the truck and can source brand-specific components quickly when needed.
