Q&A
I have natural gas heat. Should I consider switching to a heat pump?
Given our winter lows and Spire Missouri's high-efficiency rebates, a dual-fuel system pairing a heat pump with your gas furnace is often optimal. The heat pump handles moderate heating during off-peak hours, while the furnace provides efficient heat during the coldest nights and the utility's peak hours from 12:00 to 19:00, maximizing comfort and operating cost savings.
My AC stopped cooling on a hot afternoon in Downtown Clayton. How fast can a technician get here?
A technician dispatched from our shop near Shaw Park can take I-170 directly into Downtown Clayton, allowing for a 5 to 10 minute response time to most local emergencies. We prioritize no-cool calls during heat advisories to restore comfort and prevent indoor humidity from spiking, which can damage hardwood floors and furnishings common in these homes.
What are the permit and safety rules for a new AC installation in 2026?
All installations in Clayton require a permit from the City of Clayton Department of Planning and Development. Since 2026, systems using mildly flammable A2L refrigerants like R-454B must comply with updated safety standards, including leak detection systems and specific clearance requirements. We handle this permitting process and ensure all safety protocols are met for a compliant installation.
What does the new 14.3 SEER2 minimum efficiency standard mean for my replacement?
The 2026 SEER2 standard mandates higher real-world efficiency than the old SEER rating. For Clayton's 0.14 per kWh utility rate, a 16 SEER2 system can provide noticeable savings. Pairing a qualifying high-efficiency system with the active Inflation Reduction Act rebates, which have an $8,000 cap, significantly improves the financial return on your investment.
My furnace is original to my 1948 Clayton home. Should I be concerned?
A unit from 1948 is 78 years old, operating well past its typical 15-20 year service life. In humid climates like ours, older galvanized steel ductwork often develops small leaks, and aging heat exchangers can develop stress cracks that risk carbon monoxide leakage. These systems are also prone to condensate line clogs due to the high humidity, which can lead to water damage and system shutdowns.
Can my old galvanized steel ducts handle a high-MERV filter for our ozone and pollen?
May pollen peaks and summer ozone risk make high-grade filtration desirable. Installing a MERV-13 filter in an original galvanized steel duct system often causes excessive static pressure, reducing airflow and straining the blower motor. A technician should perform a static pressure test first; duct sealing or modification is frequently needed to support such filtration without compromising system performance.
How well will a new R-454B system handle our St. Louis summer heat?
While our 92°F design temperature is set for reliability, actual temperatures can exceed this, stressing the system. The newer A2L refrigerant R-454B maintains stable pressure and efficient heat transfer at these higher ambient temperatures better than older refrigerants, providing more consistent cooling capacity during the peak summer afternoons common in our region.
My Ecobee thermostat is showing an E1 alert. What does that mean?
An Ecobee E1 alert indicates the thermostat is not detecting power from the HVAC equipment. In Clayton's older homes, this commonly points to a tripped float switch from a clogged condensate line due to high humidity, a blown low-voltage fuse on the furnace control board, or a failed safety limit switch. This signal allows for targeted troubleshooting before a technician arrives.
