Ventilation System Repair on Long Island
ERV, HRV, and exhaust ventilation diagnosed with real airflow measurements — not guesswork — and repaired the same visit when parts allow.
Ventilation Problems We Repair
System runs but airflow is weak
Fouled ERV/HRV core, loaded filters, or a crushed flex duct run choking the intake or exhaust
Unit won't start at all
Failed control board, dead wall control, tripped thermal overload, or a seized blower motor
Loud humming, grinding, or rattling
Worn blower bearings, an unbalanced wheel, or a loose duct collar vibrating against framing
Water dripping from the unit
Blocked condensate drain, a clogged trap, or a drain line pitched the wrong way
Musty or stale smell despite running
Contaminated core, mold in the drain pan, or an exhaust pickup that's no longer moving air
Bathroom or kitchen still steamy
Failed exhaust fan, a stuck backdraft damper, or an exterior hood blocked by a screen or nest
Cold drafts in winter
Heat recovery core bypassed or fouled, or the HRV defrost cycle stuck open on cold days
Ventilation seems unbalanced
Supply and exhaust flows drifted out of balance, pressurizing or depressurizing the house
What Does Ventilation Repair Involve, and How Long Does It Take?
Ventilation repair begins with measured airflow at each supply and exhaust point, then inspection of the ERV/HRV core, filters, blowers, dampers, condensate drain, ducting, and controls. Most Long Island repairs — a fouled core, a failed blower or control board, a stuck damper, or a crushed flex duct run — are completed in one to three hours.
What's Included in a Ventilation Repair Visit
Why Fix Failed Ventilation Now
Our Simple Process
From call to comfort in 5 easy steps
Symptom & System Review
We identify what you have — ERV, HRV, supply-only, or exhaust-only — and confirm how the controls are supposed to run it.
Airflow Measurement
We measure actual CFM at supply and exhaust points and compare it to the system's design so we know whether the problem is equipment or duct.
Component Diagnosis
We test the blower, capacitor, control board, wall control, dampers, defrost cycle, and condensate path to isolate the failure.
Repair & Clean
We replace failed components, clean or wash the core, change filters, clear the drain, and correct crushed or disconnected duct runs.
Rebalance & Verify
We rebalance supply against exhaust, re-measure airflow, confirm quiet operation, and set the controls to a run schedule that fits your home.

Repair or Replace?
We'll help you make the right decision for your home and budget
Repair the Ventilation System When…
- The cabinet and core are intact and under 10 years old
- It needs a blower, capacitor, control board, damper, or core cleaning
- Replacement parts are still available for the model
- Duct issues are accessible and correctable
- The repair cost is well under a third of a new install
Replace the Ventilation System When…
- The core is cracked, collapsed, or no longer available
- It's 12+ years old with repeat blower or board failures
- Capacity was undersized for the home from the start
- The cabinet is corroded from long-term condensate leaks
- You're upgrading to an ERV/HRV with better efficiency and controls
