About Leonard HVAC

A Local Hvac Crew Built for New London'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 New London, CT.

We're not interested in being the cheapest quote on the page — we're the company that tells you what actually needs fixing instead of what pads the ticket. We carry the credentials New London inspectors and property managers expect to see, and we keep that documentation available on request for every job, routine or emergency.

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.

Too many homeowners in New London have a story about a tech who showed up late, quoted one price, and charged another. 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.

When you call +1-866-805-8548, you're talking to someone who understands the local permitting process, the common equipment brands installed in New London homes, and realistic scheduling given local demand. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

Emergency

Same-Day Emergency Dispatch

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our New London dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.

  • No-heat and no-cool emergency response
  • Fully stocked trucks for common failures
  • Safety shutoffs when a system poses a hazard

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.

  • Ductless mini-split installation
  • Proper ductwork sizing and sealing
  • Manufacturer warranty registration handled for you

We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.

Warning Signs

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.

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.

Bills Creeping Up Month Over Month

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

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.

What Actually Breaks Down

The Most Common Causes Behind Our Service Calls

After thousands of service calls across New London, a handful of causes show up again and again.

Dirty or Clogged FiltersA filter left too long forces the system to work harder and shortens component lifespan
Refrigerant LeaksRequires a licensed technician to locate, repair, and properly recharge
Motor StrainCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Miscalibrated ControlsSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Keeping Your System Healthy Year-Round

Seasonal Hvac Tips for New London Homeowners

New London'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.

Setting a programmable or smart thermostat to a consistent schedule reduces the number of times the system has to work hard to catch up to a big temperature swing. 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

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.

How does your pricing work?

We explain the diagnostic fee upfront and provide a flat-rate repair quote once the issue is identified.

Can you come out at night or on weekends?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

Yes, our maintenance plans include seasonal tune-ups, priority scheduling, and discounted repair rates for members.

What areas around New London do you serve?

How many times a year should my system be serviced?

Most New London 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.

Do you charge extra for after-hours or weekend calls in New London?

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 New London?
