How It Works

Three Steps From Broken To Fixed

1. Talk To Our Dispatch Team

Our Stratham 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

The Hvac Team Stratham Homeowners Actually Trust

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

You won't find us buried under layers of call-center scripts — 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, big or small.

Stratham's climate swings hard, and generic national playbooks don't always fit. That local knowledge shapes the parts we stock on the truck — 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'd rather lose a job to a lower bid than win one by cutting corners on the diagnosis, 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. We keep parts inventory stocked based on what actually fails most often on Stratham's housing stock.

Hvac in Stratham — Done Right, Not Just Done Fast

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

24/7

Emergency Hvac Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Stratham dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.

  • After-hours and weekend dispatch
  • Electrical and control board diagnostics
  • Transparent emergency pricing before work begins

If a specialty part genuinely does need to be ordered, we'll set up a safe temporary fix and give you a real timeline instead of leaving you guessing.

Residential Hvac Installation & Replacement

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Stratham homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Manual J load calculations, not rough guesses
  • Manufacturer warranty registration handled for you

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.

  • Duct sealing and cleaning
  • Annual maintenance plans with priority scheduling

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.

Warning Signs

How To Tell If Your System Is About To Fail

Most breakdowns don't happen without warning — they announce themselves for weeks before the system actually quits.

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

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

Short Cycling

Short cycling puts extra wear on the compressor and shortens the system's overall lifespan.

Strange Odors

A musty smell often points to mold or moisture buildup somewhere in the ductwork.

Repeat Breakdowns On The Same System

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

What Actually Breaks Down

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.

Airflow RestrictionWe check this first on nearly every service call
Low Refrigerant ChargeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Motor StrainUsually a quick, affordable fix once diagnosed correctly
Wiring IssuesA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Seasonal Tips

Getting Your System Ready For The Season Ahead

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. 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.

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.

No Brand Restrictions

Brands & Equipment We Work On in Stratham

Our technicians train across the major residential and commercial equipment lines, so you're not limited to a single brand's service network. 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.

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?

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?

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?

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

Will an emergency call cost more?

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

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

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

Is my presence required during the appointment?

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

Neighborhoods We Serve

Local Dispatch, Not A Distant Call Center

Housing stock varies a lot across Stratham — older homes often still run original ductwork that needs different care than the sealed, high-efficiency systems going into newer builds.

If you manage several units or a shared system across a Stratham property, ask about setting up a standing service account so every request gets handled under one consistent agreement.

Payment Options

Spreading Out The Cost Of A New System

We accept standard payment methods for repairs and smaller jobs, and we'll always tell you upfront what a given service is likely to cost so there's no last-minute scramble to figure out payment. 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.
