About Leonard HVAC

The Ductwork Repair Team Dunlap Homeowners Actually Trust

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. 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. 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, routine or emergency.

We know which neighborhoods run on older ductwork and which subdivisions were built with newer high-efficiency systems. 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.

Ask around Dunlap and you'll hear the same complaint about a lot of HVAC companies. 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 Dunlap 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 Dunlap 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

Whether it's a mid-summer breakdown or a planned system replacement, our Dunlap techs handle it with the same level of care.

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 Dunlap 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
  • Fully stocked trucks for common failures
  • Transparent emergency pricing before work begins

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

Installation

Residential Ductwork Repair Installation & Replacement

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Dunlap homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • 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

Maintenance Plans & Specialty Repairs

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

  • Multi-point safety and efficiency inspections
  • Indoor air quality testing and upgrades
  • Annual maintenance plans with priority scheduling

A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.

What To Watch For

What Dunlap Homeowners Should Watch For

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

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

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

Energy Costs Climbing With No Explanation

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.

Odors Coming From The Vents

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

Frequent Repairs

Repeated repairs on an aging system are usually the clearest sign that replacement will save more money than another patch job.

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 Dunlap's seasonal swings.

Dirty or Clogged FiltersThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Electrical & Capacitor FailuresOften shows up as clicking sounds or a system that hums but doesn't turn on
Wiring IssuesSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Seasonal Tips

What Dunlap Weather Does To Your Equipment

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.

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.

Equipment We Service

We Service Every Major System Type

Whether your Dunlap 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.

Can I finance a full HVAC replacement?

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.

How do I stay safe until the tech gets here?

If you smell gas or burning, shut off the system at the breaker and step outside, then call us immediately.

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

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

For most residential visits, yes, an adult should be present to grant access and approve any quoted work.

Neighborhoods We Serve

Serving Every Corner of Dunlap

Housing stock varies a lot across Dunlap — 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 Dunlap 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 Dunlap installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
