Frequently Asked Questions
What does the new 15 SEER2 minimum mean for my electricity bill?
The 2026 federal SEER2 standard raises the baseline efficiency for new units. For Vine Hill, with PG&E rates at $0.42 per kWh, upgrading from a 10 SEER unit to a 16 SEER2 model can cut cooling costs by roughly 30%. The federal HEEHRA rebate, with a cap of $8,000, directly lowers the upfront cost of qualifying high-efficiency heat pumps, improving the return on investment.
Our AC is original to our 1980 home. Is it on borrowed time?
A 46-year-old system is well beyond its service life. The galvanized sheet metal ductwork is also from that era. Age is the primary factor for the high rate of capacitor failure here. Electrical components degrade with thermal stress from repeated heating and cooling cycles. Proactive replacement avoids a total compressor failure during our hottest weeks.
What permits and new rules apply to a 2026 AC installation?
All replacements in Contra Costa County require a permit from the Building Inspection Department. Since 2025, systems using A2L refrigerants like R-454B are the new standard. These mildly flammable refrigerants mandate updated safety protocols: leak detectors, revised pipe sizing, and specific technician certifications. We handle the permit process and ensure the installation meets all current codes.
My Ecobee thermostat is showing an 'E1' alert. What should I do?
An Ecobee E1 error indicates it lost communication with your HVAC equipment. First, check the furnace door is securely closed, as a safety switch may be disengaged. If that's secure, the issue is often a failed control board or a blown low-voltage fuse, frequently caused by a failing component like a contractor or capacitor. This is a common diagnostic starting point for systems in the area.
I have gas heat now. Does a heat pump make sense in our climate?
Yes, a cold-climate heat pump is a viable primary heat source here. With winter lows around 40°F, modern units operate efficiently. Pairing it with your existing gas furnace as a dual-fuel or backup system can optimize costs. Operating the heat pump during off-peak hours outside of PG&E's 4 PM to 9 PM window further manages electricity expenses.
My AC just quit on a hot day near the Shell Avenue and Vine Hill Road intersection. How fast can you get here?
Our service vehicles based near I-680 can typically reach Vine Hill addresses in 15 to 25 minutes for urgent no-cool calls. We dispatch for common, quick-fix failures like capacitors first. We recommend shutting the system off at the thermostat and electrical disconnect to prevent further damage until a technician arrives.
Can my old ducts handle a better air filter for wildfire smoke and spring pollen?
Your existing galvanized sheet metal ducts with R-4.2 wrap have a robust structure, but adding a high-MERV filter creates static pressure. A MERV-13 filter for PM2.5 and pollen requires a system evaluation. We measure static pressure to ensure the blower motor isn't overworked, which can lead to reduced airflow and premature failure.
It hit 105°F last summer, but my system is only designed for 92°F. What happens?
System capacity drops as outdoor temperature exceeds its 92°F design point. At 105°F, a standard unit may only deliver 70-75% of its rated cooling, causing longer run times and higher indoor humidity. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-410A units.
