Three Steps From Broken To Fixed

1. Tell Us What's Happening

No automated menus for emergencies — a real person handles the call.

2. Diagnosis & Upfront Quote

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

3. Repair & Follow-Up

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

About Leonard HVAC

The Hvac Team Waller Homeowners Actually Trust

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

We're not interested in being the cheapest quote on the page — we're the company that tells you what actually needs fixing instead of what pads the ticket. 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 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 Waller 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 Waller's housing stock.

Core Hvac Services

From Emergency Repairs To Full Installs

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

Emergency

24/7 Emergency Heating & Cooling Repair

When your Hvac system fails without warning, waiting days for an appointment isn't an option. Our Waller dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.

  • After-hours and weekend dispatch
  • Refrigerant leak detection and repair
  • Temporary fixes when parts require special order

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

Home Comfort

Home Heating & Cooling System Upgrades

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Waller homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Proper ductwork sizing and sealing
  • Post-install performance testing

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

Air Quality

Seasonal Tune-Ups & Indoor Air Quality

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 Waller households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Duct sealing and cleaning
  • Annual maintenance plans with priority scheduling

Maintenance plan members in Waller 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

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

Repairs That Are Guaranteed

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

Fair Pricing, Verified

Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.

Not Finished Until You Say So

Our office follows up after major repairs and installs to confirm everything is holding.

Warning Signs

How To Tell If Your System Is About To Fail

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

Unusual Noises

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

Weak or Uneven Airflow

Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.

Rising Utility Bills

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

Short Cycling

This is one of the warning signs we recommend not waiting on.

Strange Odors

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

You've Called For The Same Issue Twice

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

What Sets Us Apart

The Difference Between A Repair That Sticks And One That Doesn't

Upfront, Flat-Rate Pricing

No inflated "emergency surcharge" games — the number we quote is the number you pay.

Real-Time Arrival Windows

Dispatchers give you a realistic arrival window instead of a vague "sometime today".

We Stand Behind Every Repair

If something isn't right after we leave, we come back and make it right.

Licensed, Background-Checked Techs

Financing & Maintenance Plans

Maintenance plan members get priority scheduling and discounted rates.

★★★★★

Marcus T.
Waller, TX

★★★★★

"Scheduled a fall tune-up and they caught a cracked part before it became a real problem. Techs are always polite, always on time, and clean up after themselves."

Priya S.
Waller, TX

★★★★★

"Explained the sizing calculation so I understood why they weren't just installing the same unit again. New system is noticeably quieter and our energy bill actually dropped."

Steven O.
Waller, TX

★★★★★

"Commercial dispatch was quick and the tech understood our system without needing to be walked through it. Kept our kitchen running through the weekend rush."

Tony's Kitchen
Waller, TX

★★★★★

"Got quotes from four different companies for a replacement and this was the only one that actually walked me through the load calculation. Would use them again without hesitation."

Latoya B.
Waller, TX

★★★★★

"Called at 11pm during a heat wave and honestly didn't expect anyone to pick up, let alone show up. No overnight surcharge shock — the price matched what dispatch quoted me on the phone."

Common Causes

What's Usually Behind A Breakdown

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

Dirty or Clogged FiltersWe check this first on nearly every service call
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 ControlsWe test the thermostat early in every diagnostic to rule this out
Local Climate Considerations

Getting Your System Ready For The Season Ahead

Waller's seasonal swings put real stress on a system that isn't maintained regularly. Before the coldest stretch of the year, a heating system benefits from a full safety inspection, checking the heat exchanger, ignition system, and airflow to catch any issue that could turn into a no-heat emergency.

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

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.

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

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

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?

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

Payment Flexibility When You Need It
