Who We Are

Straight Answers. Certified Techs. Real Availability.

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.

We're not the biggest name in Gresham — we're the team that shows up in the truck, not a subcontractor we've never met. 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 how we diagnose problems — 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 Gresham 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. 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 Gresham 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. 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

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

Emergency

Same-Day Emergency Dispatch

A dead system in the middle of a heat wave or a cold snap isn't just inconvenient — it can be a real safety issue for kids, pets, and older residents. Our Gresham 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
  • Electrical and control board diagnostics
  • Safety shutoffs when a system poses a hazard

We keep the truck stocked with the parts that fail most often on the equipment common to Gresham homes, which is exactly why most repairs don't require a return visit.

New System Installs & Full Replacements

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

  • Heat pump and hybrid system installs
  • Smart thermostat setup and integration
  • Manufacturer warranty registration handled for you

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

Commercial Furnace Repair Service

A retail floor, a restaurant kitchen, or an office suite can't run without stable climate control. Our commercial division services multi-zone commercial buildouts across Gresham, with after-hours work to avoid disrupting business.

  • Rooftop unit repair and replacement
  • Scheduled after-hours service windows
  • Detailed service reporting and documentation

Our commercial techs are trained to work around your customers and staff, scheduling noisy or disruptive work outside peak hours whenever possible.

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 duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Gresham households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Duct sealing and cleaning
  • Annual maintenance plans with priority scheduling

We'll show you photos of anything concerning we find, along with a plain-language explanation of what it means and whether it's urgent.

Warning Signs

Signs Your Furnace Repair System Needs Attention Now

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.

Some Rooms Never Get Comfortable

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

Bills Creeping Up Month Over Month

Gradual efficiency loss is easy to miss month to month, but it adds up fast over a season.

Short 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

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

Why Systems Fail

The Most Common Causes Behind Our Service Calls

Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.

Dirty or Clogged FiltersWe check this first on nearly every service call
Refrigerant LeaksLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Motor StrainCapacitors 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
Local Climate Considerations

Seasonal Furnace Repair Tips for Gresham Homeowners

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

Simple habits between professional visits also matter. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Brands & Equipment We Work On in Gresham

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

Common Questions

Questions Gresham Customers Ask Us Most

What's your typical response time in Gresham?

For emergency no-heat or no-cool calls, we prioritize dispatch and aim to have a technician on-site the same day, often within a couple of hours.

Will I know the cost before you begin the repair?

Yes — every job gets a clear quote before any repair work begins, so there are no surprise line items on the invoice.

Can you come out at night or on weekends?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

Do you carry insurance for work done in my home?

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

How do I know if I need a repair or a full replacement?

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 Gresham?

Yes, our maintenance plans include seasonal tune-ups, priority scheduling, and discounted repair rates for members.

How far do your technicians travel?

We cover Gresham and the surrounding communities, including the zip codes listed in our coverage section below.

Can you service both residential and commercial systems?

Property managers and business owners can request a dedicated point of contact for ongoing service.

Do you service all HVAC brands or only certain ones?

Yes, we service systems regardless of who originally installed them.

What if I can't pay for a new system all at once?

Financing options are available for qualifying replacement installations, and our team can walk you through what's currently offered.

How often should I schedule maintenance in Gresham?

Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.

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.

Will an emergency call cost more?

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

How long does a typical repair take once the tech arrives in Gresham?

More involved repairs, like a coil replacement or a refrigerant leak repair, take longer and the tech will give you a realistic estimate before starting.

Can someone else let the technician in?

Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.

Close To Home

Wherever You Are In Gresham, We're Close By

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

If you manage several units or a shared system across a Gresham property, ask about setting up a standing service account so every request gets handled under one consistent agreement.

Financing

Financing Options for Gresham Homeowners

We accept standard payment methods for repairs and smaller jobs, and we'll always tell you upfront what a given service is likely to cost so there's no last-minute scramble to figure out payment. If a rebate or local incentive program applies to your Gresham installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
