Three Steps From Broken To Fixed

1. Tell Us What's Happening

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

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. 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

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC grew one honest service call at a time in communities like Farmington. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

We're not interested in being the cheapest quote on the page — we're the team that shows up in the truck, not a subcontractor we've never met. Licensing and insurance aren't optional line items for us, 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 maintenance schedules we recommend — 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 Farmington and you'll hear the same complaint about a lot of HVAC companies. That's the gap we built Leonard HVAC to close. We track arrival windows, callback rates, and repeat-issue complaints internally so problems get caught before they become patterns, because a customer who trusts us once tends to call us again — and Farmington 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. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

Our Services

From Emergency Repairs To Full Installs

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

24/7

Same-Day Emergency Dispatch

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Farmington 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
  • 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 Farmington get resolved in a single trip, not a multi-day back-and-forth.

Residential

Residential Emergency Hvac 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 Farmington 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
  • 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.

Facilities

Business & Facility Heating and Cooling

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services light industrial and warehouse ventilation across Farmington, with service agreements built around your operating hours.

  • Multi-zone building system service
  • Preventive maintenance contracts for property managers
  • Single point of contact for multi-location businesses

Property managers working with multiple Farmington locations can set up a standing account so every site gets consistent service history and pricing.

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 Farmington households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

Maintenance plan members in Farmington get scheduling reminders automatically, so tune-ups don't fall through the cracks during a busy season.

Backed By Us, Not Just Words

A Promise We Actually Stand Behind

We Check Back

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

What To Watch For

How To Tell If Your System Is About To Fail

A little attention to how your system is running can save you a lot of money and discomfort.

New Sounds From The Unit

Ignoring new noises is one of the fastest ways to turn a small repair into a major one.

Weak or Uneven Airflow

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

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

Short Cycling

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

Odors Coming From The Vents

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

Frequent Repairs

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

Why Systems Fail

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 Farmington's seasonal swings.

Neglected Filter ChangesA filter left too long forces the system to work harder and shortens component lifespan
Refrigerant LeaksLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Miscalibrated ControlsA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Local Climate Considerations

Getting Your System Ready For The Season Ahead

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. 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.

Brands & System Types

We Service Every Major System Type

Whether your Farmington 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.

How quickly can someone get to my house?

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.

How does your pricing work?

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

What emergency Emergency Hvac services are available in Farmington?

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

Are your technicians licensed and insured?

Every technician we send is licensed in accordance with Farmington, MO requirements and carries full liability coverage.

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

As a general guideline, if a system is past 12-15 years old and facing a costly repair, replacement often makes more financial sense.

Do you offer maintenance plans in Farmington?

Plan members typically see fewer surprise breakdowns because small issues get caught during routine visits.

How far do your technicians travel?

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

Do you work on business HVAC systems too?

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

What brands and system types do you work on?

Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.

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.

What's a normal tune-up schedule?

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

Is there anything I can check myself before you arrive?

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.

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

Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.

Can someone else let the technician in?

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