Frequently Asked Questions
My AC stopped blowing cold air on a 100°F afternoon in Central Premont. How fast can someone get here?
A complete loss of cooling is treated as a priority dispatch. From our service hub near Premont City Hall, a technician can be on US-281 and to most Central Premont homes within 5 to 10 minutes. The first step on arrival is to check for a tripped breaker, a frozen evaporator coil, or a failed capacitor—common culprits for sudden failures. Quick intervention can often prevent secondary damage to the compressor.
Why does my AC struggle when it's above 95°F, even if it's newer?
All residential systems are engineered to a specific design temperature, which for Premont is 96°F. When ambient temperatures exceed this, the system's capacity drops and it must run continuously to approach the thermostat setting. The newer R-454B refrigerant, now standard, maintains slightly better efficiency and capacity at these extreme temperatures than older refrigerants. Proper sizing from a Manual J load calculation and clean, shaded outdoor units are critical for performance during our peak heat.
What are the new rules for installing an AC with the latest refrigerant?
All installations using A2L refrigerants like R-454B, which are mildly flammable, must adhere to 2026 UL 60335-2-40 safety standards. This requires specific leak detectors, revised electrical classifications, and updated service practices. In Premont, the City Building Inspections Department mandates permits for all HVAC replacements to ensure compliance with these codes and proper sizing. Only EPA Section 608 certified technicians with A2L-specific training are legally permitted to handle the refrigerant and finalize the installation.
What does the new 14.3 SEER2 minimum mean for my electricity bill?
The 2026 SEER2 standard reflects updated testing that better represents real-world conditions, including static pressure from your ductwork. For a typical 3.5-ton system in Premont, upgrading from a 10 SEER unit to a new 16 SEER2 model can reduce cooling energy use by over 30%. At the local rate of $0.14 per kWh, this represents significant savings. Pairing this with the active HEEHRA rebate, which offers up to $8,000 for qualified heat pump installations, drastically improves the payback period.
My AC is from the 1970s and still works. Should I wait for it to fail completely?
A unit installed around 1969 is now 57 years old, which is far beyond its intended service life. In Premont's humid climate, the sealed refrigerant system and internal components degrade over decades, leading to severe inefficiency. This age makes the system highly prone to condensate drain blockages from algae, as the internal pan and lines corrode. Operating it now risks a catastrophic refrigerant leak or compressor failure during our hottest days, resulting in a much more costly emergency replacement.
I have electric heat. Is switching to a heat pump worth it for our mild winters?
Yes, a modern heat pump is the most efficient electric heating option for Premont's climate. Even with winter lows around freezing, cold-climate heat pumps provide efficient heat down to about 5°F, replacing inefficient resistance strips. Shifting your heating load to the heat pump, especially during utility peak hours from 2 PM to 8 PM, can significantly reduce your winter energy bills. The HEEHRA rebate makes this electrification upgrade particularly cost-effective right now.
Can my home's ductwork handle a high-end air filter for ozone and pollen?
Your flexible ductwork with R-6 insulation has inherent limitations for static pressure. Installing a standard 1-inch MERV-13 filter, which captures fine pollen and some ozone precursors, often creates excessive airflow restriction in older systems. The solution is to upgrade to a 4- or 5-inch thick media cabinet, which provides superior filtration with lower static pressure. This modification protects both indoor air quality and the new system's efficiency and longevity.
My Ecobee thermostat is showing an E1 error. What does this mean?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Premont, this is frequently caused by a safety switch trip due to a clogged primary condensate drain line—a direct result of our high humidity and algae growth. The system shuts down to prevent water damage. Check the drain pan at the indoor air handler for overflow. Clearing the PVC drain line with a vacuum or bleach solution typically resolves the issue and restores communication.
