Most no-heat and no-cool emergencies do not come out of nowhere — they build from a dirty flame sensor, a weak capacitor, a clogged drain, or a filter no one changed. Werth-Aire’s maintenance visits catch those small problems on a calm day in the shoulder season instead of during the first cold snap or heat wave, when everyone else is calling too.
A real tune-up is not a quick glance and a sticker. We inspect and test the equipment that actually fails: ignition and combustion on heating systems, refrigerant operation and airflow on cooling systems, electrical connections, safety controls, condensate drainage, the heat exchanger, and system performance under load. And we document what we find, so you have a record of the system’s condition rather than a generic “all good.”
The best schedule for Pittsburgh is simple: heating service in early fall before the first hard freeze, and AC service in spring before the first heat wave. Our maintenance-plan members get that timing handled automatically, plus priority scheduling and repair discounts — with the terms spelled out in writing.

Why seasonal maintenance pays off
- Prevents the most common no-heat and no-cool breakdowns
- Keeps efficiency up so you are not paying to heat and cool a struggling system
- Catches unsafe combustion and cracked heat exchangers early
- Extends equipment life and protects manufacturer warranties
- Keeps airflow and humidity in check for comfort
- Gives you a documented record of system condition
What our hvac maintenance covers
Heating tune-ups
Ignition, combustion, heat exchanger, and safety-control inspection before the first freeze.

A written record of findings so you know exactly where your system stands.
Maintenance plans
Automatic scheduling, priority service, and repair discounts with terms in writing.

Our process
Full inspection
We test ignition or refrigerant operation, electrical connections, safety controls, drains, filters, and combustion or airflow under load.
Clean & adjust
We clean the components that cause failures — flame sensors, coils, drains — and tighten and calibrate as needed.
Document findings
You get a written record of the system’s condition and any items to watch, not just a sticker.
Plan the timing
Plan members get automatic seasonal scheduling, priority service, and repair discounts in writing.
What a real tune-up checks — and what a cheap 'special' skips
Combustion and the heat exchanger
On heating equipment we test ignition and combustion and inspect the heat exchanger for cracks — the safety checks a quick sticker-tune-up skips entirely.
Refrigerant and airflow
On cooling equipment we verify refrigerant operation, the temperature split, and airflow, and clean the outdoor coil — not just a visual glance and a filter swap.
Electrical and safety controls
We test capacitors, contactors, connections, limit and pressure switches, and the flame sensor under load — catching the weak parts that cause most breakdowns.
Drains, calibration, and a written record
We clear the condensate drain, calibrate the thermostat, and hand you a documented record of the system’s condition — not a generic "all good" sticker.
What a documented tune-up actually covers
A real tune-up is a hands-on inspection and test, not a quick glance and a sticker. On heating equipment we test ignition and combustion, inspect the heat exchanger, and check safety controls; on cooling equipment we verify refrigerant operation, airflow, and the condensate path. We clean the components that actually cause failures — flame sensors, coils, and drains — and we document what we find, so you have a written record of your system's condition rather than a generic all-good. That timing matters: heating service in early fall, cooling service in spring, before peak demand. Plan members get the scheduling handled automatically, plus priority service and repair discounts.
What affects the cost
Maintenance is a fixed, predictable cost — far cheaper than the emergency repair it prevents. What a plan covers:
- Seasonal tune-ups for heating and cooling on the right timing
- Priority scheduling during peak-demand cold snaps and heat waves
- Repair discounts and documented inspection records
- Reminders so you never miss the pre-season window

| Season | System | Focus |
|---|---|---|
| Early fall | Heating | Ignition, combustion, heat exchanger, safeties |
| Spring | Cooling | Refrigerant, coil, capacitor, condensate |
| Year-round | Heat pump | Both — twice yearly for charge and defrost |
