Common Questions
With gas heat, is switching to a heat pump a good idea for our winters?
Modern cold-climate heat pumps are effective for Central High's winter lows. The financial analysis involves your gas rate versus the electric rate of $0.11/kWh, especially during OG&E's peak hours from 2 PM to 7 PM. A hybrid system that uses the heat pump as the primary heater and your gas furnace as a backup for extreme cold or peak pricing can optimize annual fuel costs and comfort.
What does the new SEER2 rating mean for my electric bill and upgrade costs?
The 2026 national minimum is 14.3 SEER2, a standard that accounts for real-world static pressure. A new system meeting this will use less energy than your old unit. With Central High's average rate of $0.11 per kWh, the operational savings are clear. The federal Inflation Reduction Act rebate, capped at $8,000, directly offsets the upfront cost of qualifying high-efficiency equipment.
My Ecobee thermostat is showing an E1 alert. What does that mean here?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Central High, this is commonly caused by a safety lockout from a faulty capacitor or a pressure switch triggered during extreme heat. It's a diagnostic signal prompting a service call to check the system's electrical health before a complete failure occurs.
If my AC quits on a hot day, how quickly can a technician get to my house?
For a no-cool emergency in the Central High neighborhood, our dispatch uses OK-7 for direct access. Being located near Central High School allows for a predictable 5-10 minute travel window during most hours. We prioritize these calls to prevent heat buildup and humidity from affecting your home's interior.
What are the rules for installing a new AC with the latest refrigerant?
All installations in Central High require a permit from the Stephens County Building Department. Since 2023, new systems use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety codes (like NEC Article 440) for leak detection, charge limits, and equipment room requirements that technicians must follow by law.
Why does my AC struggle when it gets over 100 degrees?
HVAC systems in Central High are designed for a 98°F outdoor temperature. When actual temperatures exceed this design limit, the system's capacity drops and it runs continuously. The newer R-454B refrigerant standard for 2026 offers slightly better high-temperature performance than older refrigerants, but no system can overcome a significant design temperature gap without proper sizing and airflow.
Can my home's duct system handle a better air filter for ozone and pollen?
Your galvanized sheet metal with duct board is generally robust, but adding a high-MERV filter requires evaluation. A MERV-13 filter is excellent for capturing April pollen and mitigating ozone-related particulates. However, it can increase static pressure; we must measure your system's airflow to ensure the blower motor isn't strained, which would reduce efficiency and cooling capacity.
My system was installed when the house was built. Is its age a factor in needing repairs?
For a home built around 1993, the original HVAC unit is now 33 years old. In Central High, the seasonal temperature swings create significant thermal stress on electrical components. This sustained stress over decades makes a capacitor, a key part of the compressor circuit, the most likely point of failure, especially during our hot summers. A unit this age is operating well beyond its intended service life.
