How It Works

Three Steps From Broken To Fixed

1. Tell Us What's Happening

Our Portsmouth dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.

2. Get A Clear Number Before Anything Starts

A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.

3. We Fix It And Confirm It's Right

Warranty details are explained clearly so you know exactly what's covered going forward.

About Leonard HVAC

A Local Ac Repair Crew Built for Portsmouth's Climate

Leonard HVAC didn't start as a franchise chasing volume. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Portsmouth, NH.

We're not the biggest name in Portsmouth — we're the company that tells you what actually needs fixing instead of what pads the ticket. Licensing and insurance aren't optional line items for us, and we keep that documentation available on request for every job, routine or emergency.

We know which neighborhoods run on older ductwork and which subdivisions were built with newer high-efficiency systems. That local knowledge shapes the maintenance schedules we recommend — it's the difference between a tech who's guessing and a tech who's seen your exact situation a hundred times before.

Ask around Portsmouth and you'll hear the same complaint about a lot of HVAC companies. That's the gap we built Leonard HVAC to close. We track arrival windows, callback rates, and repeat-issue complaints internally so problems get caught before they become patterns, because a customer who trusts us once tends to call us again — and Portsmouth is a small enough community that reputation travels fast.

That local context saves time on every call, because we're not starting from zero on basic questions about your neighborhood or your system. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

Ac Repair in Portsmouth — Done Right, Not Just Done Fast

Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.

24/7

24/7 Emergency Heating & Cooling Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Portsmouth dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.

  • Same-day diagnostic and repair
  • Refrigerant leak detection and repair
  • Transparent emergency pricing before work begins

Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Portsmouth get resolved in a single trip, not a multi-day back-and-forth.

New System Installs & Full Replacements

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Portsmouth homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • Manufacturer warranty registration handled for you

We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.

Commercial

Commercial Climate Control Solutions

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services multi-zone commercial buildouts across Portsmouth, with after-hours work to avoid disrupting business.

  • Rooftop unit repair and replacement
  • Energy efficiency assessments for older buildings
  • Single point of contact for multi-location businesses

Our commercial techs are trained to work around your customers and staff, scheduling noisy or disruptive work outside peak hours whenever possible.

  • Filter, coil, and refrigerant level checks
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

Maintenance plan members in Portsmouth get scheduling reminders automatically, so tune-ups don't fall through the cracks during a busy season.

Don't Wait Until It Fails

How To Tell If Your System Is About To Fail

A little attention to how your system is running can save you a lot of money and discomfort.

Banging, Clicking, or Grinding Sounds

A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.

Weak or Uneven Airflow

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

Bills Creeping Up Month Over Month

A system working harder than it should to hit the same temperature shows up directly on your utility bill.

System Turns On and Off Repeatedly

This is one of the warning signs we recommend not waiting on.

Musty, Burning, or Chemical Smells

Chemical odors may signal a refrigerant leak, which requires a licensed technician to handle safely.

Frequent Repairs

Repeated repairs on an aging system are usually the clearest sign that replacement will save more money than another patch job.

Common Causes

The Most Common Causes Behind Our Service Calls

After thousands of service calls across Portsmouth, a handful of causes show up again and again.

Dirty or Clogged FiltersWe check this first on nearly every service call
Slow Leaks Over TimeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Electrical & Capacitor FailuresOften shows up as clicking sounds or a system that hums but doesn't turn on
Wiring IssuesSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Local Climate Considerations

Getting Your System Ready For The Season Ahead

Portsmouth's seasonal swings put real stress on a system that isn't maintained regularly. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

Simple habits between professional visits also matter. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Equipment We Service

Not Limited To One Manufacturer

We also service package units common on manufactured and modular homes throughout the Portsmouth area. If your system was installed by a different company entirely, that's not a problem — we service equipment regardless of who originally put it in, and we'll pull the model and serial information to confirm parts compatibility before any repair begins.

Before You Call

What You Should Know Before You Book

How fast can a Ac Repair technician arrive in Portsmouth, NH?

Standard appointments are usually scheduled within 24-48 hours, while true emergencies jump the queue.

How does your pricing work?

Yes — every job gets a clear quote before any repair work begins, so there are no surprise line items on the invoice.

Can you come out at night or on weekends?

Yes, no-heat and no-cool situations are treated as priority calls regardless of the hour.

Are your technicians licensed and insured?

Yes — licensing and insurance documentation is available on request for any job, residential or commercial.

Is it worth fixing my old system or should I replace it?

Our technicians walk you through the actual numbers — repair cost versus remaining system life versus new equipment efficiency — before making a recommendation.

What does your maintenance plan include?

Plan members typically see fewer surprise breakdowns because small issues get caught during routine visits.

How far do your technicians travel?

If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.

Are you equipped for commercial rooftop units?

Property managers and business owners can request a dedicated point of contact for ongoing service.

Do you service all HVAC brands or only certain ones?

Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.

Can I finance a full HVAC replacement?

We understand a full system replacement is a significant expense, which is why flexible payment options exist.

How often should I schedule maintenance in Portsmouth?

Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.

What should I do while I'm waiting for a technician during an emergency?

Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.

Is there an overnight or weekend surcharge?

Our pricing is explained clearly before dispatch, and any after-hours consideration is communicated upfront — never as a surprise on the final invoice.

What's the average time on-site for a service call?

Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.

Do I need to be home for a maintenance visit or repair in Portsmouth?

Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.
