What Homeowners Call Us For

The Two Repairs We Get Called For Most

Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.

AC Repair in Portsmouth

When your AC hums but won't cool, blows warm air, or keeps tripping the breaker, the fix is usually a single worn component. We test the system, find it, and replace it, often the same day. 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
  • 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 Portsmouth

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.

  • No ignition when the heat calls
  • Short cycling on and off
  • Blower running but the air isn't warm
  • New noises when the furnace kicks on

Common Problems

When Homeowners Should Call for Help

If something seems off with your comfort system, it usually comes down to one of these. Here are the problems we get called about most across Portsmouth, and how we put a stop to each.

AC Blowing Warm Air

A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.

AC repair

Furnace Won't Stay On

Short cycling wastes gas, stresses the heat exchanger, and never quite warms the house. We find the safety control tripping it and fix the cause.

Furnace repair

Rising Bills, Weak Airflow

Energy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.

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

Your ducts move the same air thousands of times a day. Years of dust, dander, and construction debris ride along until they're cleaned out.

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.

What Portsmouth Homeowners Say

★★★★★
4.8 out of 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. Our winter bills dropped noticeably the first season, and we got cooling out of the same equipment. Zero regrets on this one."

ES
Elena S.
Portsmouth, NH

"We put a ductless mini-split in the bonus room over the garage that was always freezing in winter and roasting in summer. They measured and calculated instead of eyeballing it, 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 found a refrigerant leak at a valve, repaired it, and recharged the system properly instead of just topping it off like the last guy. It has cooled perfectly ever since."

Our Promise

Our Commitment to Portsmouth Homeowners

We treat your home the way we'd treat our own: thoroughly, honestly, and with an eye on the long term. Here's the standard you can count on from us every time.

Experienced Technicians

We don't send a rookie with a gauge set and a hope. Each technician brings genuine field experience in diagnosis, safe gas and electrical work, and clean installation, the kind of depth that turns a service call into a lasting fix.

Right-Sized, Code-Compliant Work

Doing it right is built into how we install. We handle the refrigerant, gas, electrical, and airflow details precisely, pull permits where local code requires them, and commission the full system before we call it done, and we tell you what we did and why.

Maintenance That Pays for Itself

Our team believes in keeping systems alive with inexpensive seasonal care. If you want to avoid the emergency replacement, our spring and fall maintenance visits clean coils, verify the charge, and test every safety control. It's that simple. This approach is one reason we maintain a 5.0-star rating across 150+ reviews.

Common Questions

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.

Don't Wait for the Weather to Win.

Waiting only makes a failing system worse and the house less livable. Call now and our experienced team can respond fast with upfront pricing.
