What Happens After You Call

Three Steps From Broken To Fixed

1. Talk To Our Dispatch Team

Call +1-866-805-8548 and describe what your system is doing — the symptoms help us send a tech prepared with the right parts.

2. We Inspect And Explain

Ask as many questions as you want; we'd rather over-explain than leave you unsure.

3. Repair & Follow-Up

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

About Leonard HVAC

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC didn't start as a franchise chasing volume. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Radnor, OH.

You won't find us buried under layers of call-center scripts — we're the crew that answers the phone at 2am when your furnace quits in the middle of a cold snap. We carry the credentials Radnor inspectors and property managers expect to see, and we keep that documentation available on request for every job, residential or commercial.

Being local matters more than most companies let on. 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. We'd rather lose a job to a lower bid than win one by cutting corners on the diagnosis, because a customer who trusts us once tends to call us again — and Radnor 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 Radnor rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

24/7 Emergency Heating & Cooling Repair

  • Same-day diagnostic and repair
  • Fully stocked trucks for common failures
  • Safety shutoffs when a system poses a hazard

We keep the truck stocked with the parts that fail most often on the equipment common to Radnor homes, which is exactly why most repairs don't require a return visit.

Residential

New System Installs & Full Replacements

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

  • Ductless mini-split installation
  • Manual J load calculations, not rough guesses
  • 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.

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 Radnor, with after-hours work to avoid disrupting business.

  • Rooftop unit repair and replacement
  • Preventive maintenance contracts for property managers
  • Priority response tiers for commercial accounts

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

Air Quality

Seasonal Tune-Ups & Indoor Air Quality

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 Radnor households that want more than just temperature control.

  • Multi-point safety and efficiency inspections
  • UV light and filtration system installs
  • Annual maintenance plans with priority scheduling

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.

What We Promise

A Promise We Actually Stand Behind

This is the standard every Radnor technician on our team is held to.

Workmanship Warranty

Every repair comes with a workmanship warranty explained in plain terms before we leave.

Not Finished Until You Say So

Our office follows up after major repairs and installs to confirm everything is holding.

Don't Wait Until It Fails

Signs Your Hvac System Needs Attention Now

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

Unusual Noises

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.

Rising Utility Bills

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

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.

Strange Odors

A musty smell often points to mold or moisture buildup somewhere in the ductwork.

Frequent Repairs

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

What Actually Breaks Down

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
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
Wiring IssuesWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Getting Your System Ready For The Season Ahead

Radnor'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.

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.

No Brand Restrictions

We Service Every Major System Type

Whether your Radnor 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.

FAQ

Questions Radnor Customers Ask Us Most

How quickly can someone get to my house?

Standard appointments are usually scheduled within 24-48 hours, while true emergencies jump the queue.

Do you provide upfront pricing before starting work?

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.

Is Leonard HVAC a licensed HVAC contractor?

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

Is it worth fixing my old system or should I replace it?

Our technicians walk you through the actual numbers — repair cost versus remaining system life versus new equipment efficiency — before making a recommendation.

Is a service agreement worth it?

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

What areas around Radnor do you serve?

Our dispatch area extends throughout the greater Radnor region and nearby towns within Radnor, OH.

Are you equipped for commercial rooftop units?

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

What brands and system types do you work on?

If parts require special ordering for a less common brand, we'll communicate that timeline upfront.

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 often should I schedule maintenance in Radnor?

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?

Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.

Is there an overnight or weekend surcharge?

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

How long should I expect the visit to take?

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.

Do I need to be home for a maintenance visit or repair in Radnor?

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

Close To Home

Serving Every Corner of Radnor

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

If you manage several units or a shared system across a Radnor property, ask about setting up a standing service account so every request gets handled under one consistent agreement.

Financing

Payment Flexibility When You Need It

We accept standard payment methods for repairs and smaller jobs, and we'll always tell you upfront what a given service is likely to cost so there's no last-minute scramble to figure out payment. If a rebate or local incentive program applies to your Radnor installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
