What We Promise

The Leonard HVAC Guarantee

We'd rather set clear expectations upfront than make vague promises we can't back up.

Labor Backed In Writing

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

Fair Pricing, Verified

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

Satisfaction Follow-Up

A technician doesn't consider the job done until the system is tested and performing correctly.

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.

Banging, Clicking, or Grinding Sounds

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

Weak or Uneven Airflow

This is one of the most common complaints we hear on service calls across New Hampshire, NH.

Bills Creeping Up Month Over Month

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

Chemical odors may signal a refrigerant leak, which requires a licensed technician to handle safely.

Frequent Repairs

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

What Sets Us Apart

Straightforward Service, Every Single Call

Upfront, Flat-Rate Pricing

No inflated "emergency surcharge" games — the number we quote is the number you pay.

Fast Regional Response

Trained On The Systems We Install

We run background checks because you're letting someone into your home.

No Jargon, No Runaround

You make the final call — we just make sure you have the full picture.

Ways To Spread Out The Cost

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.

Neglected Filter ChangesThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Miscalibrated ControlsWe test the thermostat early in every diagnostic to rule this out
Local Climate Considerations

Seasonal Hvac Tips for New Hampshire, NH Homeowners

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.

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

We also service package units common on manufactured and modular homes throughout the New Hampshire, NH 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.
