Modern systems are sized using a Manual J load calculation based on a 94°F design temperature, which is the outdoor temperature the unit is engineered to maintain 75°F indoors. While peak summer days can exceed this, a properly sized unit will run continuously to hold temperature, which is normal. The newer R-454B refrigerant, now standard, offers excellent capacity retention in high heat compared to older R-22, maintaining better performance during the warmest parts of the day.

The Utah County Building Inspection Department requires a permit for any new HVAC system installation or refrigerant changeout. As of 2026, technicians handling the standard R-454B refrigerant must be EPA 608 certified for A2L flammable refrigerants, which involves special safety procedures for leak detection and recovery. Proper permitting ensures your system is inspected for safety and code compliance, protecting your home's value and insurance coverage.

Your insulated sheet metal ducts are generally robust, but installing a high-MERV filter requires a static pressure check. A MERV-13 filter is excellent for trapping wildfire PM2.5 and May pollen, but it can restrict airflow in older systems. We measure the static pressure before recommending an upgrade to ensure your new system's blower motor can handle it without losing efficiency or causing premature failure.

Modern cold-climate heat pumps are effective in Utah County, but the decision involves your gas rate and electric costs. A heat pump provides efficient heating down to about 5°F, but during the coldest nights, auxiliary heat may engage. To maximize savings, use a smart thermostat to avoid the utility's peak demand period from 2-8 PM. The $8,000 federal rebate makes the switch financially attractive for many Lake Shore homes.

As of 2026, all new central AC systems must meet a minimum 13.4 SEER2 rating, which is a more realistic measure of performance under static pressure. This mandate ensures modern units are significantly more efficient than your 1990s model. With Lake Shore's average electric rate of $0.11/kWh, the operational savings are meaningful. Pairing a high-efficiency unit with the active Inflation Reduction Act rebate, which can cover up to $8,000 for a qualifying heat pump, improves the financial return.

An Ecobee E160 code signals the thermostat has lost communication with the outdoor unit. In Lake Shore, this often points to a failed control board, a blown low-voltage fuse, or chewed wiring in the conduit. It's a service call that requires a technician to diagnose the control circuit. Addressing it promptly prevents the system from being stuck in a single mode, like heat only, as we approach a season change.

Units installed around 1996 are now 30 years old, which is well beyond a typical service life. Aging systems in Lake Shore are particularly prone to evaporator coil scaling from our hard water, which insulates the coil and drastically reduces cooling capacity. This scaling is often irreversible and leads to frequent, costly repairs. Planning a replacement now avoids a mid-summer failure and allows you to leverage current rebates.

First, check the thermostat settings and the circuit breaker. If the system is unresponsive, call for service; a local technician from Lake Shore can typically reach you in 15-20 minutes via I-15. We prioritize no-cool calls during heat waves to restore comfort quickly. Having your unit's model number ready when you call helps us prepare the correct parts, like a potential capacitor or contactor, for the first visit.
