Questions and Answers
Should I consider switching from my natural gas furnace to a heat pump?
For Hobart homes, a dual-fuel system pairing a heat pump with a gas furnace is often optimal. The heat pump handles moderate winter temperatures efficiently, while the furnace provides reliable heat during colder nights below freezing. To maximize savings, program the heat pump to avoid OG&E's peak electricity rates from 14:00 to 19:00, letting the gas furnace take over during that expensive window if needed.
What does the new 14.3 SEER2 minimum efficiency standard mean for my bills?
The 14.3 SEER2 federal mandate for 2026 ensures all new systems use significantly less electricity than older models. With OG&E rates at $0.11 per kWh, upgrading can cut cooling costs by roughly 20-30%. Pairing a qualifying high-SEER2 system with the active Inflation Reduction Act rebates, which have an $8,000 cap, substantially lowers the upfront investment for Hobart homeowners.
My Ecobee thermostat is showing an E1 error—what should I do?
An Ecobee E1 alert indicates the thermostat is not detecting voltage from your HVAC equipment, often signaling a system shutdown. In Hobart, this commonly points to a safety lockout from a faulty capacitor or a tripped high-pressure switch due to extreme outdoor heat. It's a prompt to power down the system at the breaker and call for service to prevent a compressor failure.
Can my home's duct system handle better air filters for dust and pollen?
Upgrading filtration is wise given Hobart's semi-arid dust risk and April pollen peak. Your existing galvanized steel ductwork is generally robust, but installing a high-MERV filter like a MERV-13 requires a static pressure check. An undersized duct system or a restrictive filter can choke airflow, so a technician should measure static pressure before making the change to ensure your blower motor isn't overworked.
Are there new safety rules for the refrigerant in a 2026 AC installation?
Yes, installations using mildly flammable A2L refrigerants like R-454B, now the standard, must follow 2026 UL 60335-2-40 safety standards. These require specific leak detectors, updated electrical classifications, and revised service procedures. All work in Hobart must be permitted through the City of Hobart Building Inspection Department, and technicians need EPA Section 608 certification for handling these new refrigerants.
My air conditioner stopped cooling on a hot afternoon—can you help quickly?
For a no-cool emergency in Downtown Hobart, our technicians can typically respond within 5-10 minutes. We dispatch from a service hub near the Kiowa County Courthouse, using US-183 for direct access to most neighborhoods. A technician will first check for the common capacitor failure and restore cooling if it's a simple, on-the-spot repair.
Is my old furnace at the end of its service life?
A unit installed around 1965 is about 61 years old, which far exceeds the typical 15-20 year lifespan. In Hobart's climate, the extreme heat cycles from daily temperature swings place repeated stress on the system's electrical components. This is the primary reason capacitors, which help start the compressor and fan motors, are the most common failure point for aging systems in town.
Why does my AC struggle when it's only 98 degrees outside?
Your system is designed to cool effectively up to its 98°F outdoor design temperature, a standard set for Hobart. When temperatures exceed this, capacity drops and the unit runs continuously to try and maintain setpoint. Modern systems using R-454B refrigerant maintain better efficiency and pressure stability in these high-heat conditions compared to older R-22 or R-410A units.
