Frequently Asked Questions

Lennox certified installation follows manufacturer-specific protocols, including verified refrigerant charging using subcooling or superheat measurements rather than pressure alone. This ensures the system delivers rated efficiency and extends compressor life, preventing the 20% efficiency loss caused by improper refrigerant charge.

Yes, but only when properly sized and installed. Oversized AC units cool quickly without running long enough to remove humidity, leaving indoor air feeling damp and uncomfortable. Correctly sized systems run longer cycles that dehumidify effectively during humid Western New York summers.

Warning signs include the system running constantly without reaching the thermostat setting, poor humidity removal, short-cycling every few minutes, and frozen evaporator coils. A narrowing temperature split between supply and return air often signals low refrigerant or restricted airflow.

Furnaces should be serviced once a year, ideally in early fall before heating season begins. Annual tune-ups verify combustion efficiency, test safety controls, and catch developing issues before they cause breakdowns during Buffalo-area cold snaps.

Common causes include ignition failures, dirty flame sensors, restricted airflow from clogged filters, and cracked heat exchangers. In Western New York winters, blocked condensate drains and frozen combustion air intakes during lake-effect storms are also frequent culprits.

Replacement makes sense when a furnace is 18–20 years old, has a cracked heat exchanger, or when heating costs have increased 30–50% over previous winters. Repeated repair calls and declining efficiency are signs you're entering a costly component failure cycle.

Proper sizing is critical because Western New York's lake-effect weather creates extreme temperature swings. Undersized units run constantly during cold snaps while oversized systems short-cycle, causing uneven temperatures, humidity problems, and accelerated component wear.

Home standby generators, like Generac units, typically last 20–30 years with proper maintenance. Regular service intervals—including oil changes, spark plug checks, and load testing—are key to ensuring the generator starts reliably when Western New York power outages occur.

Standby generators are permanently installed, start automatically during outages, and can power an entire home's critical systems. Portable generators require manual setup and fuel management. For Buffalo-area homes facing winter storm outages, standby units provide the most reliable protection for heating systems.

Yes, standby generators need annual professional maintenance to remain reliable. Service includes inspecting the fuel system, testing the automatic transfer switch, checking battery condition, and running load tests. Skipping maintenance is the leading reason generators fail to start during actual power outages.
