How It Works

A Simple Process, Start To Finish

1. Talk To Our Dispatch Team

Our Exeter 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. Repair & Follow-Up

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

Local & Licensed

The Furnace Repair Team Exeter Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. 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 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, big or small.

Being local matters more than most companies let on. 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 Exeter 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 Exeter 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.

What We Handle

Furnace Repair in Exeter — Done Right, Not Just Done Fast

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

Priority

24/7 Emergency Heating & Cooling Repair

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 Exeter dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.

  • Same-day diagnostic and repair
  • Electrical and control board diagnostics
  • Transparent emergency pricing before work begins

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.

Home Heating & Cooling System Upgrades

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. 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.

  • Heat pump and hybrid system installs
  • Smart thermostat setup and integration
  • Clean, respectful installation crews

Most installs in Exeter are completed in a single day, and we walk you through the new thermostat and any app controls before we leave.

  • Multi-point safety and efficiency inspections
  • Duct sealing and cleaning
  • Reminder scheduling so nothing gets missed

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

Warning Signs

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.

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

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

Energy Costs Climbing With No Explanation

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

Frequent On-Off Cycling

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.

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

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

Airflow RestrictionA 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
Motor StrainCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Miscalibrated ControlsWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Seasonal Furnace Repair Tips for Exeter Homeowners

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.

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.

No Brand Restrictions

Not Limited To One Manufacturer

Whether your Exeter home has a traditional split system, a ductless mini-split, a heat pump, or a hybrid dual-fuel setup, our crews are equipped to diagnose and repair it. 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

Questions Exeter Customers Ask Us Most

How quickly can someone get to my house?

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.

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?

Every technician we send is licensed in accordance with Exeter, NH requirements and carries full liability coverage.

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?

Ask your technician about current plan pricing during any service call.

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?

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?

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

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.

How many times a year should my system be serviced?

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

Is there anything I can check myself before you arrive?

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 does a typical repair take once the tech arrives in Exeter?

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.

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

Financing Options for Exeter Homeowners

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.
