The 13.4 SEER2 minimum is a federal efficiency standard for equipment manufactured in 2026. A new unit meeting this standard will consume significantly less electricity than your older model. With Lebanon's average rate of $0.16 per kWh, the annual savings can be substantial. The federal Inflation Reduction Act (HEEHRA) provides rebates with an $8,000 cap for qualified heat pump installations, which directly offsets the higher upfront cost of high-efficiency equipment. Focus on Energy also offers additional incentives up to $2,000, making a system upgrade a strong financial decision.

Standard residential equipment in our region is designed for a 88°F outdoor temperature. On days that exceed this, the system will run continuously and may not maintain the desired indoor setpoint. This is a capacity limit, not a malfunction. The new R-454B refrigerant, an A2L classified as mildly flammable, is the 2026 standard and actually has slightly better heat transfer efficiency in high ambient temperatures than older R-410A. Its use requires certified technicians following strict safety protocols for leak detection and clearance from ignition sources, but it is a safe and effective refrigerant when installed correctly.

For a no-cool emergency, we prioritize dispatch from our service hub near the Lebanon Town Hall. Using WI-109, we can typically reach any home in the Town Center area within 5 to 10 minutes. The first diagnostic steps are to check for a tripped circuit breaker at the outdoor unit and to see if the indoor furnace filter is completely blocked, as these are common, immediate causes. Our vans carry the most common parts, including capacitors and contactors, to resolve many failures on the first visit.

All new installations, especially those using A2L refrigerants like R-454B, require a permit from the Dodge County Land Resources and Parks Department. This ensures the work meets current building and mechanical codes. The 2026 standards mandate specific safety measures for A2L equipment, including leak detectors that shut the system down, revised electrical clearance rules, and permanent labels indicating refrigerant type. Only EPA Section 608 certified technicians with a Type III certification for flammable refrigerants can legally handle the installation and charging of these units. Always request the permit number and final inspection certificate from your contractor.

Modern cold-climate heat pumps are effective in Lebanon's winters, operating efficiently at temperatures well below freezing. The economics are compelling when switching from propane. To maximize savings, use the heat pump as the primary heat source. Program your thermostat to minimize use of the propane backup during the utility's peak rate hours from 2 PM to 7 PM. The system will automatically switch to the propane furnace only during the deepest cold snaps when the heat pump's capacity drops, ensuring comfort while drastically reducing your annual fuel costs.

A system from 1993 is now 33 years old, which is well beyond the typical 15-20 year service life. In Lebanon's humid continental climate, the constant cooling load puts significant stress on the refrigerant circuit. The most common failure point for units of this age is frozen evaporator coils, often caused by a combination of refrigerant leaks from degraded seals and reduced airflow from a dirty blower wheel or filter. Aging galvanized steel ductwork can also develop leaks that contribute to the moisture and pressure conditions that lead to coil freezing.

An Ecobee E1 alert indicates the thermostat has lost communication with your outdoor heat pump or air conditioner unit. In Lebanon, this is often caused by a tripped high-pressure switch, a safety device that shuts the system down if refrigerant pressure gets too high. Common triggers include a dirty outdoor condenser coil during peak pollen season, a failing condenser fan motor, or an overcharge of refrigerant. This alert prevents compressor damage. The first step is to check if the outdoor unit is iced over or if the fan is not spinning, but resolving the root cause requires a professional diagnosis.

Addressing Lebanon's May pollen peak and seasonal ozone risk requires a filter rated MERV-13 or higher. Your home's original galvanized steel ductwork is generally robust, but adding a high-MERV filter increases static pressure. This can overwhelm an older blower motor, leading to reduced airflow, frozen coils, and higher energy use. A technician should perform a static pressure test before installation. The solution is often a 4- or 5-inch thick media filter cabinet, which provides superior filtration with less airflow restriction than a standard 1-inch filter.
