About Leonard HVAC

The Hvac Team New London Homeowners Actually Trust

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 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, residential or commercial.

New London'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.

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 New London 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 New London rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

What We Handle

Complete Hvac Coverage for New London Homes & Businesses

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

Emergency

24/7 Emergency Heating & Cooling Repair

When your Hvac system fails without warning, waiting days for an appointment isn't an option. Our New London 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
  • 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 New London get resolved in a single trip, not a multi-day back-and-forth.

Installation

New System Installs & Full Replacements

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk New London homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Full system replacements, furnace to condenser
  • 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.

Commercial

Commercial Hvac Service

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services rooftop units and package systems across New London, with after-hours work to avoid disrupting business.

  • Commercial refrigeration-adjacent HVAC support
  • Energy efficiency assessments for older buildings
  • Detailed service reporting and documentation

Our commercial techs are trained to work around your customers and staff, scheduling noisy or disruptive work outside peak hours whenever possible.

Maintenance Plans & Specialty Repairs

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 indoor air quality upgrades for homes with allergy or asthma concerns for New London households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Indoor air quality testing and upgrades
  • 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.

The Leonard HVAC Guarantee

This is the standard every New London technician on our team is held to.

Repairs That Are Guaranteed

If the same issue returns within the warranty period, we come back and fix it at no additional labor cost.

No Inflated Emergency Rates

Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.

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

What New London Homeowners Should Watch For

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

Banging, Clicking, or Grinding Sounds

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

Weak or Uneven Airflow

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

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.

Musty, Burning, or Chemical Smells

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

Repeat Breakdowns On The Same System

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

What New London Says

James H.
Homeowner in New London

★★★★★

"Scheduled a fall tune-up and they caught a cracked part before it became a real problem. Techs are always polite, always on time, and clean up after themselves."

Robert K.
Homeowner in New London

★★★★★

"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Would recommend to anyone in New London needing a real replacement, not a patch job."

Michael D.
Homeowner in New London

★★★★★

"As a property manager, having a company that actually answers after-hours calls is rare. Documentation for our records was thorough and easy to file."

Coastal Retail Management
Commercial client

★★★★★

Dennis W.

Why Systems Fail

What's Usually Behind A Breakdown

None of these are unusual or embarrassing — they're just the normal wear and tear that comes with running a system through New London's seasonal swings.

Dirty or Clogged FiltersThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Refrigerant LeaksLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
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
Keeping Your System Healthy Year-Round

Getting Your System Ready For The Season Ahead

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.

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.

Equipment We Service

We Service Every Major System Type

We also service package units common on manufactured and modular homes throughout the New London 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.
