Who We Are

The Hvac Team New Lenox Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

We're not the biggest name in New Lenox — 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 New Lenox and you'll hear the same complaint about a lot of HVAC companies. 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 New Lenox 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 New Lenox homes, and realistic scheduling given local demand. We keep parts inventory stocked based on what actually fails most often on New Lenox's housing stock.

From Emergency Repairs To Full Installs

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

Emergency

24/7 Emergency Heating & Cooling Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our New Lenox dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.

  • Same-day diagnostic and repair
  • Fully stocked trucks for common failures
  • Temporary fixes when parts require special order

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.

Installation

Home Heating & Cooling System Upgrades

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk New Lenox homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Full system replacements, furnace to condenser
  • Smart thermostat setup and integration
  • Manufacturer warranty registration handled for you

We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.

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 New Lenox households that want more than just temperature control.

  • Multi-point safety and efficiency inspections
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

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 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

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.

Energy Costs Climbing With No Explanation

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.

Musty, Burning, or Chemical Smells

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.

Common Causes

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.

Airflow RestrictionWe check this first on nearly every service call
Low Refrigerant ChargeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Keeping Your System Healthy Year-Round

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 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.

Keeping vents unblocked by furniture and rugs helps maintain even airflow throughout the home. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

No Brand Restrictions

Brands & Equipment We Work On in New Lenox

Whether your New Lenox 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.
