Who We Are

The Hvac Team Union Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. 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 Union — 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.

Union's climate swings hard, and generic national playbooks don't always fit. 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 Union 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. 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 Union 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 Union rooftop unit. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

Hvac in Union — Done Right, Not Just Done Fast

Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.

24/7

Emergency Hvac Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Union 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
  • Refrigerant leak detection and repair
  • Safety shutoffs when a system poses a hazard

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.

Installation

New System Installs & Full Replacements

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. 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.

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • Clean, respectful installation crews

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.

  • Rooftop unit repair and replacement
  • Scheduled after-hours service windows
  • Priority response tiers for commercial accounts

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

Air Quality

Maintenance Plans & Specialty Repairs

Most emergency breakdowns start as a small, ignorable warning sign months earlier. Beyond standard tune-ups, we also handle indoor air quality upgrades for homes with allergy or asthma concerns for Union households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Duct sealing and cleaning
  • Reminder scheduling so nothing gets missed

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

What To Watch For

Signs Your Hvac System Needs Attention Now

Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.

Unusual Noises

A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.

Airflow That's Dropped Off

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

Rising Utility Bills

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

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

You've Called For The Same Issue Twice

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

Keeping Your System Healthy Year-Round

Seasonal Hvac Tips for Union Homeowners

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

No Brand Restrictions

Not Limited To One Manufacturer

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

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

Are your technicians licensed and insured?

When does a repair stop making sense?

Do you offer financing for new system installations?

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?

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?

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.

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

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

Union was incorporated as a township by an act of the New Jersey Legislature on February 17, 1853, from portions of Bethlehem Township. Clinton Town was formed on April 5, 1865, within portions of the township, and became an independent municipality in 1895. The township was named for Union Furnace, which was producing iron from 1742 until the 1780s. The name "Union" was chosen over the alternative "Rockhill", which was a community at the southern end of the township.
