What Happens After You Call

A Simple Process, Start To Finish

1. Call & Describe The Problem

No automated menus for emergencies — a real person handles the call.

2. We Inspect And Explain

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

3. We Fix It And Confirm It's Right

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

Who We Are

A Local Emergency Hvac Crew Built for Cohasset's Climate

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 Cohasset, MA.

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. We carry the credentials Cohasset inspectors and property managers expect to see, and we keep that documentation available on request for every job, routine or emergency.

Cohasset's climate swings hard, and generic national playbooks don't always fit. 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.

Too many homeowners in Cohasset 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'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 Cohasset 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 Cohasset's housing stock.

What We Handle

From Emergency Repairs To Full Installs

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

Emergency

Same-Day Emergency Dispatch

A dead system in the middle of a heat wave or a cold snap isn't just inconvenient — it can be a real safety issue for kids, pets, and older residents. Our Cohasset 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
  • Transparent emergency pricing before work begins

Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Cohasset 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 Cohasset 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
  • 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.

Business

Business & Facility Heating and Cooling

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services multi-zone commercial buildouts across Cohasset, with priority response for facilities that can't afford downtime.

  • Multi-zone building system service
  • Scheduled after-hours service windows
  • Detailed service reporting and documentation

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

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 Cohasset households that want more than just temperature control.

  • Multi-point safety and efficiency inspections
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

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

What We Promise

What Happens If Something's Not Right

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

Repairs That Are Guaranteed

Details vary by job type and are always shared upfront, never buried in fine print.

No Inflated Emergency Rates

Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.

Not Finished Until You Say So

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

Don't Wait Until It Fails

How To Tell If Your System Is About To Fail

A little attention to how your system is running can save you a lot of money and discomfort.

Unusual Noises

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

Some Rooms Never Get Comfortable

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

Energy Costs Climbing With No Explanation

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

Short 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.

Common Causes

The Most Common Causes Behind Our Service Calls

After thousands of service calls across Cohasset, a handful of causes show up again and again.

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
Electrical & Capacitor FailuresCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Wiring IssuesA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
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. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

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.

Equipment We Service

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.

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.

What's a normal tune-up schedule?

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?

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

Is there an overnight or weekend surcharge?

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