Three Steps From Broken To Fixed

1. Call & Describe The Problem

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

2. Get A Clear Number Before Anything Starts

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

3. We Fix It And Confirm It's Right

Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.

Local & Licensed

A Local Furnace Repair Crew Built for Shrewsbury's Climate

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. 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. 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 Shrewsbury 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 Shrewsbury is a small enough community that reputation travels fast.

Our office team is based locally too, not routed through an out-of-state call center that's never seen a Shrewsbury rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

What We Handle

From Emergency Repairs To Full Installs

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

Emergency

Same-Day Emergency Dispatch

When your Furnace Repair system fails without warning, waiting days for an appointment isn't an option. Our Shrewsbury 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
  • Safety shutoffs when a system poses a hazard

If a specialty part genuinely does need to be ordered, we'll set up a safe temporary fix and give you a real timeline instead of leaving you guessing.

New System Installs & Full Replacements

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Shrewsbury 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

Every install ends with a performance test, confirming airflow, temperature split, and refrigerant charge are all where they should be before we consider the job finished.

Business

Business & Facility Heating and Cooling

Downtime in a commercial space costs money every hour a system is offline. Our commercial division services rooftop units and package systems across Shrewsbury, with after-hours work to avoid disrupting business.

  • Commercial refrigeration-adjacent HVAC support
  • Energy efficiency assessments for older buildings
  • Priority response tiers for commercial accounts

We understand that a commercial call isn't just about comfort, it's about keeping a business open.

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

  • Filter, coil, and refrigerant level checks
  • Indoor air quality testing and upgrades
  • Discounted repair rates for plan members

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

Our Guarantee

The Leonard HVAC Guarantee

Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.

Labor Backed In Writing

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

Fair Pricing, Verified

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

Not Finished Until You Say So

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

Don't Wait Until It Fails

Signs Your Furnace Repair System Needs Attention Now

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

New Sounds From The Unit

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

Weak or Uneven Airflow

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

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.

System Turns On and Off Repeatedly

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

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

Frequent Repairs

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

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 Shrewsbury's seasonal swings.

Neglected Filter ChangesWe check this first on nearly every service call
Low Refrigerant ChargeRequires a licensed technician to locate, repair, and properly recharge
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Wiring IssuesWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Seasonal Furnace Repair Tips for Shrewsbury Homeowners

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

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.

Brands & System Types

Brands & Equipment We Work On in Shrewsbury

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

Before You Call

What You Should Know Before You Book

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.

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.

Do you offer 24/7 emergency repair?

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

Are your technicians licensed and insured?

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?

We never push a replacement when a straightforward repair will genuinely solve the problem.

What does your maintenance plan include?

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

Do you service the zip codes near Shrewsbury?

Our dispatch area extends throughout the greater Shrewsbury region and nearby towns within Shrewsbury, MO.

Can you service both residential and commercial systems?

Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.

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?

We understand a full system replacement is a significant expense, which is why flexible payment options exist.

How often should I schedule maintenance in Shrewsbury?

Most Shrewsbury homes benefit from two tune-ups a year — one before cooling season and one before heating season.

Is there anything I can check myself before you arrive?

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

Do you charge extra for after-hours or weekend calls in Shrewsbury?

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

How long should I expect the visit to take?

Straightforward fixes like a capacitor swap or a thermostat replacement are often finished in well under an hour.

Can someone else let the technician in?

For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.

Wherever You Are In Shrewsbury, We're Close By

Qualifying installations can be financed through options we'll walk you through during your in-home estimate, with terms explained clearly before you commit to anything. If a rebate or local incentive program applies to your Shrewsbury installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
