How It Works

Three Steps From Broken To Fixed

1. Tell Us What's Happening

No automated menus for emergencies — a real person handles the call.

2. We Inspect And Explain

You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.

3. Job Finished, Then Checked Again

If anything feels off after we leave, a follow-up call gets a technician back out to make it right.

Who We Are

A Local Hvac Crew Built for Exeter's Climate

Leonard HVAC grew one honest service call at a time in communities like Exeter. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

We're not the biggest name in Exeter — 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 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'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 Exeter 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 Exeter rooftop unit. We keep parts inventory stocked based on what actually fails most often on Exeter's housing stock.

Our Services

From Emergency Repairs To Full Installs

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

Priority

Emergency Hvac Repair

When your Hvac system fails without warning, waiting days for an appointment isn't an option. Our Exeter dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.

  • After-hours and weekend dispatch
  • Refrigerant leak detection and repair
  • Temporary fixes when parts require special order

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

Residential

New System Installs & Full Replacements

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Exeter homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • 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.

Commercial

Business & Facility Heating and Cooling

A retail floor, a restaurant kitchen, or an office suite can't run without stable climate control. Our commercial division services multi-zone commercial buildouts across Exeter, with service agreements built around your operating hours.

  • Commercial refrigeration-adjacent HVAC support
  • Scheduled after-hours service windows
  • Priority response tiers for commercial accounts

We understand that a commercial call isn't just about comfort, it's about keeping a business open.

Air Quality

Seasonal Tune-Ups & Indoor Air Quality

Preventive maintenance is the cheapest repair you'll ever pay for, because it's the one that prevents the bigger bill. Beyond standard tune-ups, we also handle humidifier, dehumidifier, and air purifier installation for Exeter households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.

Our Guarantee

A Promise We Actually Stand Behind

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

Repairs That Are Guaranteed

Every repair comes with a workmanship warranty explained in plain terms before we leave.

Fair Pricing, Verified

We quote a flat rate before work begins and that number doesn't change once you approve it.

Not Finished Until You Say So

A technician doesn't consider the job done until the system is tested and performing correctly.

What To Watch For

Signs Your Hvac System Needs Attention Now

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

Unusual Noises

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

Some Rooms Never Get Comfortable

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

Energy Costs Climbing With No Explanation

Gradual efficiency loss is easy to miss month to month, but it adds up fast over a season.

Short Cycling

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

Odors Coming From The Vents

A burning smell should never be ignored — it can indicate an electrical issue that needs immediate attention.

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.

Why Systems Fail

Why Hvac Systems Fail in Exeter Homes

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
Refrigerant LeaksLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Motor StrainOften 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
Seasonal Tips

What Exeter Weather Does To Your Equipment

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

Keeping vents unblocked by furniture and rugs helps maintain even airflow throughout the home. 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 Exeter 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.

FAQ

What You Should Know Before You Book

How quickly can someone get to my house?

Because our trucks are staged near Exeter, average arrival windows run faster than what national chains typically offer.

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.

Do you offer 24/7 emergency repair?

Our emergency line runs 24 hours a day, including nights, weekends, and holidays.

Is Leonard HVAC a licensed HVAC contractor?

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

How do I know if I need a repair or a full replacement?

We never push a replacement when a straightforward repair will genuinely solve the problem.

Do you offer maintenance plans in Exeter?

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

Do you service the zip codes near Exeter?

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?

Yes, we run separate residential and commercial divisions, both fully licensed and equipped for their respective equipment.

Can you work on a system installed by another company?

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

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

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.

How do I stay safe until the tech gets here?

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 Exeter?

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.

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 Exeter

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

If you manage several units or a shared system across a Exeter 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

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 Exeter installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
