Q&A
Our AC seems to leak water indoors. Is this related to its age?
A 65-year-old home in Lawson Heights often has an AC system that is 15-20 years old. Units this age commonly develop condensate drain blockages. The humid continental climate here produces substantial moisture during cooling cycles. Over decades, algae and debris accumulate in the drain line, leading to overflow. This is a frequent, age-related service call for galvanized steel ductwork systems from that era.
What if my air conditioner stops on the hottest day in Lawson Heights?
A 'No-Cool' emergency requires a quick diagnosis, often a tripped breaker or clogged drain. From our service area near Lawson Heights Park, we can dispatch a technician via PA-28. Typical response to most Lawson Heights addresses is 15 to 25 minutes. This allows us to secure the system and prevent secondary water damage from a blocked condensate pan.
Why does my AC struggle when it's above 90 degrees?
Your system was designed for a 88°F outdoor temperature, a standard calculation for this region. On days reaching the mid-90s, the capacity drops and the unit runs continuously. Modern systems using R-454B refrigerant maintain better efficiency and pressure at these higher temperatures than older R-410A units, but all systems have a performance limit above their design condition.
Should I consider a heat pump with my existing gas furnace?
A dual-fuel system using your gas furnace as backup is strategic for Lawson Heights. During the winter low of 20°F, a heat pump operates efficiently, but gas provides reliable heat during deeper cold snaps. You can program the system to use the heat pump during off-peak hours and switch to gas during utility peak periods from 2 PM to 7 PM, optimizing for both comfort and cost.
Can my home's ductwork support a better air filter for pollen and PM2.5?
Your galvanized steel ducts with fiberglass wrap are generally robust. Installing a high-efficiency MERV-13 filter is possible but requires a static pressure check. Systems in 1960s homes were not designed for such restrictive filters. A technician must measure airflow to ensure the blower motor isn't strained, which could reduce cooling capacity and increase energy use during May pollen peaks.
Is it worth replacing an old unit just to meet the new SEER2 rules?
The 2026 federal minimum is 14.3 SEER2. An older 10 SEER unit running on $0.16/kWh electricity is significantly more expensive. Modern systems often achieve 16-18 SEER2, reducing runtime and cost. The active Inflation Reduction Act rebates, with an $8,000 cap, combined with a ~$300 utility rebate from Duquesne Light, can make the upgrade cost-effective within a few years.
My Ecobee thermostat is showing an 'E1' alert. What does that mean?
An Ecobee E1 code indicates it cannot detect a signal from your outdoor AC unit. In our climate, this is commonly caused by a safety lockout from a clogged condensate drain switch, a tripped high-pressure switch from overworking on a hot day, or a failed capacitor. It's a specific alert that prevents compressor damage and requires a technician to diagnose the root cause.
What are the permit and safety rules for a new AC installation?
All HVAC replacements in Allegheny County require a permit from the Department of Economic Development - Building Standards Division. Since 2023, systems using A2L refrigerants like R-454B, which are mildly flammable, mandate specific safety standards. These include leak detectors, revised pipe sizing, and special technician certifications. Proper permitting ensures the installation meets 2026 codes for safety and efficiency.
