Local & Licensed

Straight Answers. Certified Techs. Real Availability.

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 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, 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.

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 Union 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 Union homes, and realistic scheduling given local demand. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

Furnace Repair in Union — Done Right, Not Just Done Fast

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

Emergency

Emergency Furnace Repair Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Union 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
  • Electrical and control board diagnostics
  • Transparent emergency pricing before work begins

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

Residential

Residential Furnace 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 Union 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
  • Manual J load calculations, not rough guesses
  • 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.

  • Commercial refrigeration-adjacent HVAC support
  • Scheduled after-hours service windows
  • Priority response tiers for commercial accounts

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

  • Seasonal tune-ups, spring and fall
  • Indoor air quality testing and upgrades
  • Discounted repair rates for plan members

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

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.

Banging, Clicking, or Grinding Sounds

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

Airflow That's Dropped Off

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

Energy Costs Climbing With No Explanation

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

Frequent On-Off Cycling

A system that won't hold a steady cycle is often fighting a sizing issue, a thermostat problem, or a refrigerant imbalance.

Musty, Burning, or Chemical Smells

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

Repeat Breakdowns On The Same System

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

Angela M.

Coastal Retail Management

Rachel P.

Why Systems Fail

Why Furnace Repair Systems Fail in Union Homes

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

Airflow RestrictionThe 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
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Miscalibrated ControlsSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Seasonal Tips

What Union 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 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.

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

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.

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

Is Leonard HVAC a licensed HVAC contractor?

What areas around Union do you serve?

If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.

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.

Can you work on a system installed by another company?

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

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?

Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.

Is there an overnight or weekend surcharge?

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

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

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?

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

Close To Home

Serving Every Corner of Union

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

We also work regularly with homeowners associations, property management companies, and multi-unit buildings throughout Union.

Making A Replacement Affordable

Spreading Out The Cost Of A New System

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 Union installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
