FAQs
Our power bill is high. Would a new AC unit actually save us money with today's prices?
Yes, upgrading from a system likely below 10 SEER to a new 16+ SEER2 unit can cut cooling costs by over 30%. At LG&E's current rate of $0.13 per kWh, that represents significant annual savings. The federal HEEHRA rebates, active with an $8,000 cap, directly reduce the upfront cost, making the payback period for a high-efficiency unit in Fort Knox very favorable.
With spring pollen and summer ozone, can our old duct system handle a better air filter?
Your existing galvanized sheet metal ducts are structurally sound for upgraded filtration. However, the external fiberglass wrap can leak if disturbed. We recommend testing static pressure before installing a MERV-13 filter; a modern variable-speed blower can often compensate, but sealing duct joints may be necessary to handle the increased airflow resistance and effectively capture pollen and fine particulates.
Our heat went out overnight near the Patton Museum. How fast can you get here?
For a no-heat emergency in that area, dispatch from our shop near KY-313 allows for a 15 to 25 minute response. We route directly via the Fort Knox access roads, bypassing typical Radcliff traffic. A technician will first verify your gas furnace ignition and check for a tripped safety switch or failed inducer motor, common immediate fixes to restore heat.
Our Ecobee thermostat is showing an E1 alert. What does that mean here?
An Ecobee E1 alert indicates the thermostat is not detecting power from your HVAC system's control circuit. In Fort Knox homes, this is commonly caused by a tripped float switch due to condensate drain line algae blockage, a blown 3-amp fuse on the furnace control board, or a failed safety limit switch. It's a diagnostic signal prompting a check of these specific points before a compressor or heat exchanger issue.
What should we know about permits and safety for a new AC installation?
All HVAC replacements in Hardin County require a permit from the Building and Codes Department, which includes a post-installation inspection. Since 2023, new systems use A2L mildly flammable refrigerants like R-454B. This mandates specific safety standards: leak detectors must be installed in the indoor unit, and technicians require EPA Section 608 certification for A2Ls. Proper permitting ensures this safety protocol is followed for your home.
Our AC stopped working on the hottest day. How old is our system and what's the most likely culprit?
Homes in the Radcliff-Fort Knox Corridor built around 1978 often have original HVAC equipment approaching 50 years. At that age, the sealed refrigerant circuit is vulnerable to leaks, and internal components like capacitors and contactors wear out. The high humidity here also accelerates algae growth in the condensate drain line, a frequent failure point that can trigger a safety shutdown to prevent water damage.
Why does our AC struggle when it's only 95 degrees out?
Your system was designed for a 91°F outdoor temperature, a standard based on historical data. When actual temps exceed this design limit, the system runs continuously and cannot maintain the desired indoor delta T. Modern units using R-454B refrigerant maintain better capacity and efficiency in these high-heat conditions compared to older R-22 systems, which see a severe performance drop-off.
We have gas heat but hear about heat pumps. Is switching a good idea for our Fort Knox winters?
Modern cold-climate heat pumps are effective in Kentucky winters, but the decision involves your gas versus electric rate balance. During LG&E's peak hours (2 PM to 8 PM), a heat pump in heating mode could be costly. A hybrid system, which uses a heat pump as the primary heater and switches to your gas furnace during extreme cold or peak rates, often provides the optimal year-round efficiency and comfort for this area.
