Common Questions
Can our older ductwork handle a better air filter for spring pollen and ozone?
Fairfax's May pollen peak and summer ozone risk make MERV-13 filtration desirable. However, original galvanized steel ducts are often undersized for modern static pressure requirements. We must measure external static pressure before installing a high-MERV filter; otherwise, reduced airflow can cause freezing and premature compressor failure in your system.
Why does our AC struggle when it hits 95°F outside?
Your system is engineered for a 89°F design temperature, a local code standard based on historical data. When ambient temperatures exceed this by 6 degrees, capacity drops significantly. The newer R-454B refrigerant in modern systems offers slightly better high-temperature performance, but proper sizing and shade are critical to bridge this design gap on the hottest Fairfax days.
We use gas heat now. Is a heat pump a practical switch for Fairfax winters?
Modern cold-climate heat pumps operate efficiently in Fairfax's winter lows. The key is evaluating Duke Energy Ohio's peak hours (2-7 PM) and their time-of-use rates. A correctly sized, inverter-driven heat pump can reduce your gas dependence significantly. For existing gas furnaces, a dual-fuel hybrid system often provides the most cost-effective and resilient heating solution.
Our air conditioner is original to our 1940s Fairfax home. Should we be worried?
Systems from that era are now over 80 years old. Galvanized steel ductwork and original components are far beyond their service life. In Fairfax's humid climate, this age directly contributes to the primary failure point: condensate line clogs. The line's internal surfaces degrade, trapping more algae and mold, which leads to frequent backups and potential water damage.
Our Ecobee thermostat is showing an E1 alert. What's urgent about that?
An Ecobee E1 code signals a compressor lockout, typically from a previous fault like a refrigerant pressure error or flame sensor issue. In Fairfax, this often follows a condensate overflow safety switch trip due to our humidity. The system requires a manual reset and professional diagnosis to address the root cause—ignoring it leads to a complete lack of cooling.
Are there new safety rules for the refrigerant in a 2026 AC installation?
Yes. The Village of Fairfax Building Department requires permits for all refrigerant changes. The new standard R-454B is an A2L refrigerant, classified as mildly flammable. 2026 codes mandate specific leak detectors, revised service port placements, and updated ventilation requirements in mechanical rooms. Only EPA-certified technicians handling A2Ls should perform this work.
If our AC quits on a hot day near the Fairfax Recreation Center, how fast can a technician arrive?
A dispatch from our service center places a truck on I-71 within minutes. From the highway, we reach the Fairfax Residential District in 10 to 15 minutes. We prioritize no-cool calls during heat advisories to prevent indoor temperature spikes and protect sensitive equipment from sustained high-pressure operation.
What does the new 14.3 SEER2 minimum mean for our electricity bills?
The 2026 SEER2 standard mandates a 5-10% efficiency gain over older models. At Fairfax's average rate of $0.14 per kWh, upgrading a 2.5-ton system can save over $100 annually. The active Inflation Reduction Act rebate, capped at $8,000, often covers most of the premium for a high-SEER2 unit, making the payback period for neighbors here notably short.
