Our Old Greenwich dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.

3. Repair & Follow-Up

Warranty details are explained clearly so you know exactly what's covered going forward.

Local & Licensed

A Local Emergency Hvac Crew Built for Old Greenwich's Climate

Leonard HVAC didn't start as a franchise chasing volume. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Old Greenwich, CT.

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.

Old Greenwich'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.

Ask around Old Greenwich 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 Old Greenwich 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 Old Greenwich rooftop unit. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

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

  • After-hours and weekend dispatch
  • Refrigerant leak detection and repair

  • Smart thermostat setup and integration
  • Clean, respectful installation crews

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

Specialized

Seasonal Tune-Ups & Indoor Air Quality

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 Old Greenwich households that want more than just temperature control.

  • Multi-point safety and efficiency inspections
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.

What We Promise

What Happens If Something's Not Right

We'd rather set clear expectations upfront than make vague promises we can't back up.

Repairs That Are Guaranteed

Every repair comes with a workmanship warranty explained in plain terms before we leave.

Price Match Commitment

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

Signs Your Emergency Hvac System Needs Attention Now

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

New Sounds From The Unit

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

Some Rooms Never Get Comfortable

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

Bills Creeping Up Month Over Month

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

System Turns On and Off Repeatedly

A system that won't hold a steady cycle is often fighting a sizing issue, a thermostat problem, or a refrigerant imbalance.

Odors Coming From The Vents

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.

Why Systems Fail

What's Usually Behind A Breakdown

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

Airflow RestrictionThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Low Refrigerant ChargeA 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 IssuesA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Local Climate Considerations

Seasonal Emergency Hvac Tips for Old Greenwich Homeowners

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.

Common Questions

What You Should Know Before You Book

How fast can a Emergency Hvac technician arrive in Old Greenwich, CT?

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

Will I know the cost before you begin the repair?

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

Do you offer 24/7 emergency repair?

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

Are your technicians licensed and insured?

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

When does a repair stop making sense?

We never push a replacement when a straightforward repair will genuinely solve the problem.

Is a service agreement worth it?

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

Do you service the zip codes near Old Greenwich?

We cover Old Greenwich and the surrounding communities, including the zip codes listed in our coverage section below.

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.

Do you offer financing for new system installations?

We understand a full system replacement is a significant expense, which is why flexible payment options exist.

How often should I schedule maintenance in Old Greenwich?

Most Old Greenwich 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?

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?

Our pricing is explained clearly before dispatch, and any after-hours consideration is communicated upfront — never as a surprise on the final invoice.

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

More involved repairs, like a coil replacement or a refrigerant leak repair, take longer and the tech will give you a realistic estimate before starting.

Is my presence required during the appointment?

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

Local Coverage

Local Dispatch, Not A Distant Call Center

Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.

Larger properties get the same upfront pricing and licensed technicians as a single-family service call, just coordinated at scale.

Making A Replacement Affordable

Payment Flexibility When You Need It

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 Old Greenwich installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
