Booking A Service Call

A Simple Process, Start To Finish

1. Tell Us What's Happening

Call +1-866-805-8548 and describe what your system is doing — the symptoms help us send a tech prepared with the right parts.

2. Get A Clear Number Before Anything Starts

A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.

3. Job Finished, Then Checked Again

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

Who We Are

A Local Ductwork Repair Crew Built for Concord's Climate

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 Concord, NH.

You won't find us buried under layers of call-center scripts — we're the crew that answers the phone at 2am when your furnace quits in the middle of a cold snap. We carry the credentials Concord inspectors and property managers expect to see, and we keep that documentation available on request for every job, big or small.

We know which neighborhoods run on older ductwork and which subdivisions were built with newer high-efficiency systems. 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 Concord and you'll hear the same complaint about a lot of HVAC companies. That's the gap we built Leonard HVAC to close. Every dispatcher, every technician, and every follow-up call is held to the same standard, because a customer who trusts us once tends to call us again — and Concord 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 Concord homes, and realistic scheduling given local demand. We keep parts inventory stocked based on what actually fails most often on Concord's housing stock.

Home Heating & Cooling System Upgrades

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Concord 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.

Maintenance

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 duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Concord households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

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

What Happens If Something's Not Right

Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.

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.

Don't Wait Until It Fails

How To Tell If Your System Is About To Fail

A little attention to how your system is running can save you a lot of money and discomfort.

Unusual Noises

A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.

Airflow That's Dropped Off

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

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

Musty, Burning, or Chemical Smells

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

Frequent Repairs

We'll always tell you honestly when a repair is the better call versus when it isn't.

What Actually Breaks Down

Why Ductwork Repair Systems Fail in Concord Homes

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

Dirty or Clogged FiltersA 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
Wiring IssuesWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Getting Your System Ready For The Season Ahead

Concord's seasonal swings put real stress on a system that isn't maintained regularly. 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.

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.

Brands & System Types

Not Limited To One Manufacturer

Whether your Concord 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.

Before You Call

What You Should Know Before You Book

How quickly can someone get to my house?

Standard appointments are usually scheduled within 24-48 hours, while true emergencies jump the queue.

Do you provide upfront pricing before starting work?

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

Can you come out at night or on weekends?

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

Do you carry insurance for work done in my home?

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?

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

Do you offer maintenance plans in Concord?

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

How far do your technicians travel?

Our dispatch area extends throughout the greater Concord region and nearby towns within Concord, NH.

Can you service both residential and commercial systems?

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?

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

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?

Most Concord 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?

Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.

Is there an overnight or weekend surcharge?

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

What's the average time on-site for a service call?

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

As of the 2020 census the population was 43,976, making it the third largest city in New Hampshire behind Manchester and Nashua.
