About Leonard HVAC

The Emergency Hvac Team New London Homeowners Actually Trust

Leonard HVAC grew one honest service call at a time in communities like New London. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout New London, CT.

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 New London inspectors and property managers expect to see, and we keep that documentation available on request for every job, big or small.

New London's climate swings hard, and generic national playbooks don't always fit. 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.

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. 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 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. We keep parts inventory stocked based on what actually fails most often on New London's housing stock.

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 humidifier, dehumidifier, and air purifier installation for New London households that want more than just temperature control.

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

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

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

Repairs That Are Guaranteed

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

Fair Pricing, Verified

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

Not Finished Until You Say So

Our office follows up after major repairs and installs to confirm everything is holding.

Don't Wait Until It Fails

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

Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.

Some Rooms Never Get Comfortable

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

Rising Utility Bills

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

System Turns On and Off Repeatedly

This is one of the warning signs we recommend not waiting on.

Musty, Burning, or Chemical Smells

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

You've Called For The Same Issue Twice

If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.

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 FiltersWe check this first on nearly every service call
Low Refrigerant ChargeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Seasonal Emergency Hvac Tips for New London Homeowners

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Before the coldest stretch of the year, a heating system benefits from a full safety inspection, checking the heat exchanger, ignition system, and airflow to catch any issue that could turn into a no-heat emergency.

Clearing debris, leaves, and overgrown landscaping away from an outdoor condenser unit gives it room to breathe and keeps it running efficiently. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

No Brand Restrictions

Brands & Equipment We Work On in New London

Our technicians train across the major residential and commercial equipment lines, so you're not limited to a single brand's service network. 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.

Will I know the cost before you begin the repair?

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?

Do you carry insurance for work done in my home?

Every technician we send is licensed in accordance with New London, CT requirements and carries full liability coverage.

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.

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?

Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.

What should I do while I'm waiting for a technician during an emergency?

If you smell gas or burning, shut off the system at the breaker and step outside, then call us immediately.

Will an emergency call cost more?

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

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.

Can someone else let the technician in?

Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.
