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. We invest in ongoing training so our techs recognize a failing capacitor, a cracked heat exchanger, or a refrigerant leak before it turns into an emergency.

You won't find us buried under layers of call-center scripts — we're the team that shows up in the truck, not a subcontractor we've never met. Every job we run is backed by full liability coverage and current state licensing, 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 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 Stratham 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 Stratham is a small enough community that reputation travels fast.

When you call +1-866-805-8548, you're talking to someone who understands the local permitting process, the common equipment brands installed in Stratham homes, and realistic scheduling given local demand. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

What We Handle

From Emergency Repairs To Full Installs

Whether it's a mid-summer breakdown or a planned system replacement, our Stratham techs handle it with the same level of care.

Emergency

Same-Day Emergency Dispatch

A dead system in the middle of a heat wave or a cold snap isn't just inconvenient — it can be a real safety issue for kids, pets, and older residents. Our Stratham 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
  • Safety shutoffs when a system poses a hazard

We keep the truck stocked with the parts that fail most often on the equipment common to Stratham homes, which is exactly why most repairs don't require a return visit.

Installation

Residential Hvac Installation & Replacement

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Stratham homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • Post-install performance testing

Every install ends with a performance test, confirming airflow, temperature split, and refrigerant charge are all where they should be before we consider the job finished.

Seasonal Tune-Ups & Indoor Air Quality

Most emergency breakdowns start as a small, ignorable warning sign months earlier. Beyond standard tune-ups, we also handle humidifier, dehumidifier, and air purifier installation for Stratham households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Duct sealing and cleaning
  • Reminder scheduling so nothing gets missed

We'll show you photos of anything concerning we find, along with a plain-language explanation of what it means and whether it's urgent.

Don't Wait Until It Fails

What Stratham Homeowners Should Watch For

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

Banging, Clicking, or Grinding Sounds

Ignoring new noises is one of the fastest ways to turn a small repair into a major one.

Airflow That's Dropped Off

This is one of the most common complaints we hear on service calls across Stratham.

Bills Creeping Up Month Over Month

A tune-up often identifies exactly what's driving the extra energy use.

Short Cycling

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

Strange Odors

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

You've Called For The Same Issue Twice

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

Why Systems Fail

Why Hvac Systems Fail in Stratham Homes

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

Neglected Filter ChangesA filter left too long forces the system to work harder and shortens component lifespan
Low Refrigerant ChargeRequires a licensed technician to locate, repair, and properly recharge
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Miscalibrated ControlsWe test the thermostat early in every diagnostic to rule this out
Keeping Your System Healthy Year-Round

What Stratham Weather Does To Your Equipment

Stratham's seasonal swings put real stress on a system that isn't maintained regularly. Before the coldest stretch of the year, a heating system benefits from a full safety inspection, checking the heat exchanger, ignition system, and airflow to catch any issue that could turn into a no-heat emergency.

Setting a programmable or smart thermostat to a consistent schedule reduces the number of times the system has to work hard to catch up to a big temperature swing. 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 Stratham 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.

Common Questions

What You Should Know Before You Book

How fast can a Hvac technician arrive in Stratham, NH?

For emergency no-heat or no-cool calls, we prioritize dispatch and aim to have a technician on-site the same day, often within a couple of hours.

Will I know the cost before you begin the repair?

Our policy is simple: you approve the number before we touch the system.

Can you come out at night or on weekends?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

Is Leonard HVAC a licensed HVAC contractor?

We maintain current credentials because it protects both our customers and our team.

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

As a general guideline, if a system is past 12-15 years old and facing a costly repair, replacement often makes more financial sense.

What does your maintenance plan include?

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

Do you service the zip codes near Stratham?

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

Can you service both residential and commercial systems?

Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.

Do you service all HVAC brands or only certain ones?

If parts require special ordering for a less common brand, we'll communicate that timeline upfront.

Do you offer financing for new system installations?

Financing options are available for qualifying replacement installations, and our team can walk you through what's currently offered.

What's a normal tune-up schedule?

Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.

Is there anything I can check myself before you arrive?

Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.

Do you charge extra for after-hours or weekend calls in Stratham?

Ask about current after-hours rates when you call +1-866-805-8548.

How long does a typical repair take once the tech arrives in Stratham?

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

Can someone else let the technician in?

For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.

Neighborhoods We Serve

Serving Every Corner of Stratham

Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.

Larger properties get the same upfront pricing and licensed technicians as a single-family service call, just coordinated at scale.

Financing

Spreading Out The Cost Of A New System

A full system replacement is one of the bigger home expenses most people face, and we don't expect everyone to pay it in a single lump sum. If a rebate or local incentive program applies to your Stratham installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
