What To Expect When You Call +1-866-805-8548

1. Talk To Our Dispatch Team

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

2. Diagnosis & Upfront Quote

Ask as many questions as you want; we'd rather over-explain than leave you unsure.

3. We Fix It And Confirm It's Right

Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.

Local & Licensed

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. 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 team that shows up in the truck, not a subcontractor we've never met. Licensing and insurance aren't optional line items for us, and we keep that documentation available on request for every job, routine or emergency.

Being local matters more than most companies let on. That local knowledge shapes how we diagnose problems — it's the difference between a tech who's guessing and a tech who's seen your exact situation a hundred times before.

Trust in this industry gets eroded fast, and it takes real consistency to earn it back. 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.

Our office team is based locally too, not routed through an out-of-state call center that's never seen a Portsmouth rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

  • Electrical and control board diagnostics
  • Transparent emergency pricing before work begins

Installation

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 financing and rebate options where available before a single piece of equipment gets ordered.

  • Full system replacements, furnace to condenser
  • Proper ductwork sizing and sealing
  • Clean, respectful installation crews

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

Air Quality

Seasonal Tune-Ups & Indoor Air Quality

A seasonal tune-up catches the kind of wear that turns into a mid-summer no-cool call. Beyond standard tune-ups, we also handle indoor air quality upgrades for homes with allergy or asthma concerns for Portsmouth households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Indoor air quality testing and upgrades
  • Annual maintenance plans with priority scheduling

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

What We Promise

The Leonard HVAC Guarantee

We'd rather set clear expectations upfront than make vague promises we can't back up.

Labor Backed In Writing

No Inflated Emergency Rates

Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.

Not Finished Until You Say So

What To Watch For

How To Tell If Your System Is About To Fail

Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.

New Sounds From The Unit

Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.

Some Rooms Never Get Comfortable

Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.

Rising Utility Bills

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.

Odors Coming From The Vents

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

Repeat Breakdowns On The Same System

If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.

Common Causes

The Most Common Causes Behind Our Service Calls

Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.

Neglected Filter ChangesA filter left too long forces the system to work harder and shortens component lifespan
Refrigerant LeaksA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Keeping Your System Healthy Year-Round

What Portsmouth Weather Does To Your Equipment

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

Clearing debris, leaves, and overgrown landscaping away from an outdoor condenser unit gives it room to breathe and keeps it running efficiently. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Equipment We Service

We Service Every Major System Type

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.

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.

Do you offer maintenance plans in Portsmouth?

Yes, our maintenance plans include seasonal tune-ups, priority scheduling, and discounted repair rates for members.

How far do your technicians travel?

Do you service all HVAC brands or only certain ones?

Yes, we service systems regardless of who originally installed them.

What if I can't pay for a new system all at once?

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

How many times a year should my system be serviced?

Most Portsmouth homes benefit from two tune-ups a year — one before cooling season and one before heating season.

How do I stay safe until the tech gets here?

If you smell gas or burning, shut off the system at the breaker and step outside, then call us immediately.

Is there an overnight or weekend surcharge?

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

How long should I expect the visit to take?

Straightforward fixes like a capacitor swap or a thermostat replacement are often finished in well under an hour.

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

For most residential visits, yes, an adult should be present to grant access and approve any quoted work.
