Three Steps From Broken To Fixed

1. Talk To Our Dispatch Team

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

A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.

3. Repair & Follow-Up

If anything feels off after we leave, a follow-up call gets a technician back out to make it right.

Local & Licensed

The Hvac Installation Team Gillespie Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

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. We carry the credentials Gillespie inspectors and property managers expect to see, and we keep that documentation available on request for every job, routine or emergency.

Being local matters more than most companies let on. 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.

Too many homeowners in Gillespie 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 Gillespie 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 Gillespie 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.

Our Services

From Emergency Repairs To Full Installs

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

Priority

Same-Day Emergency Dispatch

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Gillespie dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.

  • After-hours and weekend dispatch
  • Refrigerant leak detection and repair
  • 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 Gillespie get resolved in a single trip, not a multi-day back-and-forth.

Home Comfort

Home Heating & Cooling System Upgrades

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

  • Full system replacements, furnace to condenser
  • Manual J load calculations, not rough guesses
  • Post-install performance testing

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

  • Detailed service reporting and documentation

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 Gillespie households that want more than just temperature control.

  • Multi-point safety and efficiency inspections
  • Duct sealing and cleaning
  • 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

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

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

Price Match Commitment

We quote a flat rate before work begins and that number doesn't change once you approve it.

We Check Back

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

Don't Wait Until It Fails

Signs Your Hvac Installation System Needs Attention Now

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

Banging, Clicking, or Grinding Sounds

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

Some Rooms Never Get Comfortable

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

Energy Costs Climbing With No Explanation

A system working harder than it should to hit the same temperature shows up directly on your utility bill.

System Turns On and Off Repeatedly

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

Strange Odors

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

Repeat Breakdowns On The Same System

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

What Sets Us Apart

Straightforward Service, Every Single Call

Quoted Before We Start

You'll know the cost before a wrench touches your system.

Dispatch From Nearby, Not Across Town

Emergency calls get moved to the front of the line automatically.

Warrantied Workmanship

We don't consider a job finished until the system is actually performing correctly.

Licensed, Background-Checked Techs

We run background checks because you're letting someone into your home.

No Jargon, No Runaround

You make the final call — we just make sure you have the full picture.

Flexible Options For Every Budget

Maintenance plan members get priority scheduling and discounted rates.

Why Systems Fail

Why Hvac Installation Systems Fail in Gillespie Homes

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

Airflow RestrictionWe check this first on nearly every service call
Low Refrigerant ChargeRequires a licensed technician to locate, repair, and properly recharge
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Miscalibrated ControlsA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Local Climate Considerations

Seasonal Hvac Installation Tips for Gillespie Homeowners

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.

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.

Brands & System Types

We Service Every Major System Type

Whether your Gillespie home has a traditional split system, a ductless mini-split, a heat pump, or a hybrid dual-fuel setup, our crews are equipped to diagnose and repair it. 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.
