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. We Inspect And Explain

You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.

3. Repair & Follow-Up

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

About Leonard HVAC

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

We're not the biggest name in Burlington — we're the team that shows up in the truck, not a subcontractor we've never met. Every job we run is backed by full liability coverage and current state licensing, and we keep that documentation available on request for every job, big or small.

Being local matters more than most companies let on. That local knowledge shapes the maintenance schedules we recommend — 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 Burlington 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 Burlington 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 Burlington homes, and realistic scheduling given local demand. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

What We Handle

From Emergency Repairs To Full Installs

Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.

Emergency

24/7 Emergency Heating & Cooling Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Burlington 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
  • Electrical and control board diagnostics
  • Transparent emergency pricing before work begins

Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Burlington get resolved in a single trip, not a multi-day back-and-forth.

Home Comfort

Residential Ac Repair Installation & Replacement

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Burlington homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • 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.

Commercial

Business & Facility Heating and Cooling

Downtime in a commercial space costs money every hour a system is offline. Our commercial division services rooftop units and package systems across Burlington, with after-hours work to avoid disrupting business.

  • Commercial refrigeration-adjacent HVAC support
  • Scheduled after-hours service windows
  • Detailed service reporting and documentation

Property managers working with multiple Burlington locations can set up a standing account so every site gets consistent service history and pricing.

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

  • Multi-point safety and efficiency inspections
  • UV light and filtration system installs
  • Annual maintenance plans with priority scheduling

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

What We Promise

What Happens If Something's Not Right

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

Labor Backed In Writing

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

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

If anything feels off after we leave, one call gets a tech back to your Burlington address.

Don't Wait Until It Fails

Signs Your Ac Repair System Needs Attention Now

Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.

New Sounds From The Unit

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

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.

Energy Costs Climbing With No Explanation

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

System Turns On and Off Repeatedly

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

Odors Coming From The Vents

A musty smell often points to mold or moisture buildup somewhere in the ductwork.

Repeat Breakdowns On The Same System

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

Why Choose Us

Straightforward Service, Every Single Call

Quoted Before We Start

Common Causes

The Most Common Causes Behind Our Service Calls

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

Airflow RestrictionThe 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
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Keeping Your System Healthy Year-Round

What Burlington Weather Does To Your Equipment

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.

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

We Service Every Major System Type

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.

Before You Call

What You Should Know Before You Book

What's your typical response time in Burlington?

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

Do you provide upfront pricing before starting 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.

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.

Is it worth fixing my old system or should I replace it?

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 Burlington?

Ask your technician about current plan pricing during any service call.

How far do your technicians travel?

If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.

Can you service both residential and commercial systems?

Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.

Can you work on a system installed by another company?

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?

Financing options are available for qualifying replacement installations, and our team can walk you through what's currently offered.

How many times a year should my system be serviced?

Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.

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

Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.

Will an emergency call cost more?

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

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

Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.

Do I need to be home for a maintenance visit or repair in Burlington?

For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.

Close To Home

Wherever You Are In Burlington, We're Close By

Housing stock varies a lot across Burlington — older homes often still run original ductwork that needs different care than the sealed, high-efficiency systems going into newer builds.

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

Payment Options

Financing Options for Burlington Homeowners

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