Q&A
My Fayette home's AC is from the 1990s. Why does it keep freezing up?
Most original systems in Downtown Fayette homes are approaching 30 years old. With an average build year of 1938, a unit installed in the 90s is now at the end of its service life. Aging components, particularly the refrigerant metering device, can cause low refrigerant charge and improper evaporator coil temperatures. This makes the condensate line freezing a common failure point, as the coil temperature drops below the dew point for extended periods.
Our AC stopped cooling during a hot afternoon near the Fayette County Courthouse. How fast can a tech get here?
A service vehicle dispatched from our shop can be at your Downtown Fayette home within 5-10 minutes. We route via US-40 for direct access to the historic district. This quick response is critical for diagnosing a no-cool emergency, which is often a simple fix like a tripped breaker or clogged filter, preventing a more costly compressor failure.
Is it worth upgrading my old AC to meet the new 2026 efficiency standards?
The current minimum SEER2 standard is 14.3, but modern systems easily achieve 16-18 SEER2. At Fayette's average rate of $0.14 per kWh, a high-efficiency unit can cut cooling costs significantly. The active Inflation Reduction Act (HEEHRA) rebates, with an $8,000 cap, combined with a $200 West Penn Power rebate, make the net investment for a compliant system very favorable.
With gas heat, should I consider a heat pump for my Fayette home?
For a home with gas heat, a dual-fuel system pairing a heat pump with a gas furnace is often ideal. The heat pump efficiently handles moderate heating loads, using cheaper electricity during off-peak hours outside of 2 PM to 7 PM. During Fayette's colder winter lows, the system automatically switches to gas heat, which provides more consistent warmth at a lower cost than a heat pump struggling in extreme cold.
My Ecobee thermostat is showing an E1 error. What does this mean for my system?
An Ecobee E1 alert indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Fayette, this often points to a safety lockout on the furnace control board or a tripped high-pressure switch on the outdoor unit. It's a protective signal preventing damage, commonly related to a dirty filter, failing capacitor, or the condensate line freezing issue prevalent in older systems.
What are the permit and safety rules for a new AC installation in Fayette now?
All installations requiring refrigerant work must be permitted through the Fayette County Building Code Office. Since January 2023, new systems use A2L refrigerants like R-454B, which are mildly flammable. 2026 codes mandate specific safety standards: leak detection systems, updated service ports, and permanently affixed refrigerant classification labels. Only EPA Section 608 certified technicians can legally handle this refrigerant.
Why does my AC struggle to keep up on the hottest days of our Fayette summer?
HVAC systems are sized for a design temperature, which in Fayette is 87°F. On days that exceed this, the system will run continuously to try and maintain setpoint, creating a perceived shortfall. The newer R-454B refrigerant standard for 2026 maintains better efficiency and capacity at these higher ambient temperatures compared to older R-410A, but proper system sizing via a Manual J load calculation remains essential.
Can my home's old ductwork handle a better air filter for pollen and dust?
Galvanized steel ductwork, common in Fayette's older homes, is durable but often undersized for modern airflow needs. While upgrading to a MERV-13 filter helps capture May's peak pollen and year-round PM2.5 particulates, it increases static pressure. A technician must measure your system's static pressure to ensure it can handle the filter without starving the blower motor, which would reduce airflow and efficiency.
