AC Repair & Furnace Repair in Portsmouth

When the air conditioning quits or the furnace won't light, you need a technician who finds the real problem and fixes it the same day.

AC Repair in Portsmouth

Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. 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.

  • AC running but blowing warm air
  • Outdoor unit humming but not starting
  • Ice on the refrigerant lines or indoor coil
  • Water leaking near the indoor unit

Furnace Repair in Portsmouth

When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.

  • No ignition when the heat calls
  • Short cycling on and off
  • Cold air from the vents in heating mode
  • New noises when the furnace kicks on

Common Heating & Cooling Problems in Portsmouth

Wondering if it's bad enough to call? These are the most common heating and cooling problems we fix in homes across the area.

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

A system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.

System replacement

Dusty Air & Musty Smells

Dust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.

Rooms That Never Get Comfortable

Mini-splits deliver precise heating and cooling to a single zone, run whisper-quiet, and sip electricity compared to window units.

Why Work With Us

What Sets Us Apart

Fast Appointments

A house at 90 degrees is an every-hour problem, so we treat it like one. Same-day appointments across Portsmouth, with evenings and weekends available.

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.

Repair-First Mindset

Plenty of companies sell a new system the moment yours hiccups. We diagnose first, explain what actually failed, and only recommend replacement when the math genuinely favors it.

Built to Last

We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.

Knowing Portsmouth is half the job. We've learned which neighborhoods run undersized ducts, how the local climate loads systems season to season, and what inspectors here look for on permits, and we put that knowledge to work on every job so it's done right the first time.

What Clients Say

What Portsmouth Homeowners Say

★★★★★
Rated 4.8/5 · 150+ reviews

"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

"We put a ductless mini-split in the bonus room over the garage that was always freezing in winter and roasting in summer. They sized it for the actual room instead of guessing, and the install was clean and quick. That room is finally usable year-round."

OA
Omar A.
Portsmouth, NH

"The AC would run for hours and never hit the set temperature. Their tech pressure-tested the lines, fixed the leak, and weighed in the correct charge instead of just topping it off like the last guy. It has cooled perfectly ever since."

FAQ

HVAC Questions

Most air conditioner repairs in Portsmouth 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 Portsmouth 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 Portsmouth 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.
