Our Guarantee

The Leonard HVAC Guarantee

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

Repairs That Are Guaranteed

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

Satisfaction Follow-Up

Don't Wait Until It Fails

What Connecticut, CT Homeowners Should Watch For

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

Banging, Clicking, or Grinding Sounds

Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.

Airflow That's Dropped Off

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

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

Short 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

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

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

Neglected Filter ChangesThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Refrigerant LeaksLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Electrical & Capacitor FailuresUsually a quick, affordable fix once diagnosed correctly
Wiring IssuesWe 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

Connecticut, CT's seasonal swings put real stress on a system that isn't maintained regularly. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

Simple habits between professional visits also matter. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

We also service package units common on manufactured and modular homes throughout the Connecticut, CT 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.
