A Simple Process, Start To Finish

1. Tell Us What's Happening

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

2. Get A Clear Number Before Anything Starts

Ask as many questions as you want; we'd rather over-explain than leave you unsure.

3. We Fix It And Confirm It's Right

Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.

Who We Are

A Local Furnace Repair Crew Built for Casselberry'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 Casselberry, FL.

We're not the biggest name in Casselberry — we're the team that shows up in the truck, not a subcontractor we've never met. We carry the credentials Casselberry inspectors and property managers expect to see, and we keep that documentation available on request for every job, residential or commercial.

Casselberry'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.

Trust in this industry gets eroded fast, and it takes real consistency to earn it back. 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 Casselberry 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 Casselberry rooftop unit. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

From Emergency Repairs To Full Installs

We cover the full range of heating, cooling, and air quality work Casselberry properties actually need.

24/7

Same-Day Emergency Dispatch

When your Furnace Repair system fails without warning, waiting days for an appointment isn't an option. Our Casselberry dispatch team prioritizes no-heat and no-cooling calls 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 Casselberry get resolved in a single trip, not a multi-day back-and-forth.

Home Heating & Cooling System Upgrades

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Casselberry homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

  • Full system replacements, furnace to condenser
  • Manual J load calculations, not rough guesses
  • Clean, respectful installation crews

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

  • Multi-point safety and efficiency inspections
  • Indoor air quality testing and upgrades

Backed By Us, Not Just Words

A Promise We Actually Stand Behind

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

Details vary by job type and are always shared upfront, never buried in fine print.

No Inflated Emergency Rates

We Check Back

A technician doesn't consider the job done until the system is tested and performing correctly.

Warning Signs

Signs Your Furnace Repair 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

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

Weak or Uneven Airflow

This is one of the most common complaints we hear on service calls across Casselberry.

Bills Creeping Up Month Over Month

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

System Turns On and Off Repeatedly

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

Strange Odors

Chemical odors may signal a refrigerant leak, which requires a licensed technician to handle safely.

Repeat Breakdowns On The Same System

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

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

Neglected Filter ChangesThe 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
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Local Climate Considerations

Getting Your System Ready For The Season Ahead

Casselberry's seasonal swings put real stress on a system that isn't maintained regularly. 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.

No Brand Restrictions

Brands & Equipment We Work On in Casselberry

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

Frequently Asked Questions About Furnace Repair in Casselberry

How quickly can someone get to my house?

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

How does your pricing work?

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

Can you come out at night or on weekends?

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

Is Leonard HVAC a licensed HVAC contractor?

We maintain current credentials because it protects both our customers and our team.

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

Our technicians walk you through the actual numbers — repair cost versus remaining system life versus new equipment efficiency — before making a recommendation.

Do you offer maintenance plans in Casselberry?

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

How far do your technicians travel?

Our dispatch area extends throughout the greater Casselberry region and nearby towns within Casselberry, FL.

Are you equipped for commercial rooftop units?

Yes, we run separate residential and commercial divisions, both fully licensed and equipped for their respective equipment.

Can you work on a system installed by another company?

If parts require special ordering for a less common brand, we'll communicate that timeline upfront.

Do you offer financing for new system installations?

Ask about financing during your in-home estimate to see what fits your situation.

How many times a year should my system be serviced?

Most Casselberry 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?

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?

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 should I expect the visit to take?

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.

Local Coverage

Wherever You Are In Casselberry, We're Close By

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

We also work regularly with homeowners associations, property management companies, and multi-unit buildings throughout Casselberry.

Payment Options

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