How It Works

What To Expect When You Call +1-866-805-8548

1. Tell Us What's Happening

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

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

3. Job Finished, Then Checked Again

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 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.

We're not interested in being the cheapest quote on the page — we're the company that tells you what actually needs fixing instead of what pads the ticket. We carry the credentials Marietta inspectors and property managers expect to see, and we keep that documentation available on request for every job, big or small.

Being local matters more than most companies let on. 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.

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 Marietta is a small enough community that reputation travels fast.

That local context saves time on every call, because we're not starting from zero on basic questions about your neighborhood or your system. We keep parts inventory stocked based on what actually fails most often on Marietta's housing stock.

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

24/7

Same-Day Emergency Dispatch

When your Hvac system fails without warning, waiting days for an appointment isn't an option. Our Marietta 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
  • Electrical and control board diagnostics
  • 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 Marietta get resolved in a single trip, not a multi-day back-and-forth.

New System Installs & Full Replacements

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Marietta 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
  • Manufacturer warranty registration handled for you

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.

What We Promise

A Promise We Actually Stand Behind

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

Repairs That Are Guaranteed

If the same issue returns within the warranty period, we come back and fix it at no additional labor cost.

Fair Pricing, Verified

If a competitor's written quote for the same scope of work is genuinely lower, ask us about it.

We Check Back

If anything feels off after we leave, one call gets a tech back to your Marietta address.

Warning Signs

Signs Your Hvac 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

Ignoring new noises is one of the fastest ways to turn a small repair into a major one.

Weak or Uneven Airflow

This is one of the most common complaints we hear on service calls across Marietta.

Rising Utility Bills

A system working harder than it should to hit the same temperature shows up directly on your utility bill.

Frequent On-Off Cycling

Short cycling puts extra wear on the compressor and shortens the system's overall lifespan.

Odors Coming From The Vents

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

Frequent Repairs

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

Common Causes

The Most Common Causes Behind Our Service Calls

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

Neglected Filter ChangesThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsUsually a quick, affordable fix once diagnosed correctly
Miscalibrated ControlsWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Seasonal Hvac Tips for Marietta Homeowners

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.

Equipment We Service

Not Limited To One Manufacturer

Whether your Marietta 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.

Before You Call

What You Should Know Before You Book

What's your typical response time in Marietta?

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

Do you provide upfront pricing before starting work?

Our policy is simple: you approve the number before we touch the system.

Do you offer 24/7 emergency repair?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

Do you carry insurance for work done in my home?

We maintain current credentials because it protects both our customers and our team.

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

As a general guideline, if a system is past 12-15 years old and facing a costly repair, replacement often makes more financial sense.

What does your maintenance plan include?

Yes, our maintenance plans include seasonal tune-ups, priority scheduling, and discounted repair rates for members.

What areas around Marietta 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.

Do you work on business HVAC systems too?

Property managers and business owners can request a dedicated point of contact for ongoing service.

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?

Ask about financing during your in-home estimate to see what fits your situation.

What's a normal tune-up schedule?

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?

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

Will an emergency call cost more?

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

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

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.

Is my presence required during the appointment?

Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.

Close To Home

Serving Every Corner of Marietta

Housing stock varies a lot across Marietta — 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 Marietta.

Financing

Spreading Out The Cost Of A New System

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