Common Questions
What are the new rules for installing an air conditioner in 2026?
All new installations in Stephens County require a permit from the Stephens County Building Department. Crucially, as of 2026, systems using the new A2L refrigerants like R-454B must comply with updated safety standards. These include specific requirements for leak detection, sensor placement, and equipment room ventilation that your contractor must follow, ensuring a safe and code-compliant installation.
I heard there are new efficiency rules and big rebates. What does this mean for my upgrade?
Federal law now requires new central air conditioners to meet a minimum 14.3 SEER2 rating, a significant jump in efficiency. Pairing a high-SEER2 unit with the active Inflation Reduction Act (HEEHRA) rebates, which can cover up to $8,000, dramatically lowers upfront cost. With Oklahoma Electric Cooperative's $300 rebate and our local rate of $0.11 per kWh, the operational savings make a modern system a strong financial decision.
With gas heat, is switching to a heat pump a good idea for our winters?
For a home in Comanche using gas heat, a dual-fuel system pairing a heat pump with your existing furnace is often the optimal transition. The heat pump handles moderate heating efficiently, especially during the utility peak hours of 2 PM to 7 PM when electricity demand is high. The gas furnace then provides reliable, cost-effective heat during our coldest nights, ensuring comfort and managing operating costs effectively.
My AC system is original to my home. What should I expect as it ages?
A system installed when the home was built in 1965 is now 61 years old, which is far beyond its expected service life. In Comanche, the repeated extreme heat cycles to meet our 99°F design temperature accelerate capacitor degradation, making it the most common point of failure. The galvanized sheet metal ductwork may also have developed leaks over decades, reducing overall system efficiency and capacity.
My air conditioner stopped working on a hot day in Downtown Comanche. How quickly can a technician arrive?
For a no-cool emergency, a dispatch from our service center near Comanche City Park provides direct access to US Highway 81. This routing allows a technician to reach most homes in the Downtown area within 5 to 10 minutes. We prioritize these calls during peak cooling hours to prevent indoor temperatures from rising rapidly.
My Ecobee thermostat is showing an E4 alert. What does that mean here?
An Ecobee E4 alert indicates the thermostat is not detecting a call for cooling from your HVAC equipment. In Comanche, this often points to a failed control signal, commonly due to a blown 24-volt fuse in the air handler or a compromised safety switch. Given our climate and typical system age, it can also be an early warning of capacitor failure, which a technician should diagnose promptly to prevent a complete system shutdown.
Can my current HVAC system handle better filters for our ozone and pollen problems?
Comanche's ozone risk and April pollen peak make advanced filtration like MERV-13 desirable. However, your existing galvanized sheet metal with duct board system may not have been designed for the higher static pressure these filters create. A technician must measure static pressure to ensure your blower motor can handle the restriction without reducing airflow or causing premature failure.
Why does my AC struggle when it gets over 100 degrees?
HVAC systems in Comanche are engineered to a 99°F design temperature, a standard based on historical data. When ambient temperatures exceed this, as they often do, the system's capacity drops and it must run continuously. Modern units using the new R-454B refrigerant maintain better performance and efficiency in these high-temperature conditions compared to older R-22 or R-410A systems.
