Local & Licensed

The Furnace Repair Team Lake Mary Homeowners Actually Trust

Leonard HVAC grew one honest service call at a time in communities like Lake Mary. 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.

We know which neighborhoods run on older ductwork and which subdivisions were built with newer high-efficiency systems. 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 Lake Mary 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 track arrival windows, callback rates, and repeat-issue complaints internally so problems get caught before they become patterns, because a customer who trusts us once tends to call us again — and Lake Mary is a small enough community that reputation travels fast.

That local context saves time on every call, because we're not starting from zero on basic questions about your neighborhood or your system. We keep parts inventory stocked based on what actually fails most often on Lake Mary's housing stock.

Home Comfort

New System Installs & Full Replacements

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • Clean, respectful installation crews

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

Facilities

Business & Facility Heating and Cooling

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 light industrial and warehouse ventilation across Lake Mary, with priority response for facilities that can't afford downtime.

  • Rooftop unit repair and replacement
  • Energy efficiency assessments for older buildings
  • Single point of contact for multi-location businesses

We understand that a commercial call isn't just about comfort, it's about keeping a business open.

Air Quality

Maintenance Plans & Specialty Repairs

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

  • Seasonal tune-ups, spring and fall
  • Indoor air quality testing and upgrades
  • Annual maintenance plans with priority scheduling

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

Warning Signs

What Lake Mary Homeowners Should Watch For

Most breakdowns don't happen without warning — they announce themselves for weeks before the system actually quits.

Unusual Noises

A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.

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

A tune-up often identifies exactly what's driving the extra energy use.

Frequent On-Off Cycling

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.

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 Lake Mary's seasonal swings.

Airflow RestrictionThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeA 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
Miscalibrated ControlsSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Seasonal Tips

Getting Your System Ready For The Season Ahead

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

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.

Equipment We Service

We Service Every Major System Type

We also service package units common on manufactured and modular homes throughout the Lake Mary 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.
