What Homeowners Call Us For

Keeping Homes Cool in Summer and Warm in Winter

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 Nashua

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
  • Frozen coil or iced-over lines
  • Condensate backing up around the air handler
AC repair costs and common fixes

Furnace Repair in Nashua

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
  • New noises when the furnace kicks on

Common Problems

Common Air Conditioning and Heating Problems in Nashua

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

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

A system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.

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

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

Additions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.

Why Work With Us

Why Homeowners Trust Us

Fast Appointments

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

Local Experts

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.

We Fix the Cause

Lasting comfort comes from fixing the cause, not the symptom. We find why your system failed and shut that down for good, then back the work with a real guarantee.

Local Expertise

A Trusted HVAC Contractor Close to Home

For over 15 years, Nashua HVAC has been the go-to team for HVAC service in this part of NH. Our locally based technicians understand the unique challenges that local comfort systems face, from the age of local housing stock and its ductwork quirks to coastal air that corrodes condenser coils.

Our team doesn't just swap parts and leave. We check the airflow, the charge, and the electrical supply driving the failure common to local homes and businesses. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.

Rated 4.8/5 · 150 reviews

"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team got it running the same day. They clearly understood what downtime costs a Nashua business, and they came back the next week to fully service the second unit. They've got all our locations now."

"We signed up for their maintenance plan a couple of years back and it has already paid for itself. On the fall tune-up they caught a cracked igniter that would have left us with no heat in January, and replaced it on the spot. Best subscription we have."

YC
Yvonne C.
Nashua, 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 kept up through every heat wave since."

Our Commitment

Built on Trust, Backed by Results

Choosing who works on your HVAC system is a real decision. Here's what sets us apart from other local service companies.

Licensed HVAC Technicians

The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.

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

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 Nashua HVAC way.

Common Questions

Your Questions, Answered

Most air conditioner repairs in Nashua 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 Nashua 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 Nashua 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.
