Common Questions
Our Ecobee thermostat is showing an 'E4' alert. What does this mean for our HVAC system?
An Ecobee E4 alert indicates the thermostat has lost communication with your HVAC equipment's control board for over 30 minutes. In Mona, this often points to a failed control board, a blown low-voltage fuse from a short, or a safety switch trip—like a clogged condensate drain line triggering the float switch. Dust accumulation on the board itself is also common. This alert allows for proactive service before a complete system shutdown occurs during peak heat.
Our AC stopped cooling entirely on a hot afternoon. How quickly can a technician arrive in Mona City Center?
A no-cool emergency in Mona City Center receives priority dispatch. A technician can be en route from our service hub near Mona City Park within minutes, using I-15 for direct access to your neighborhood. We consistently achieve a 5 to 10 minute response window during business hours to diagnose critical failures like a locked compressor or refrigerant loss before the indoor temperature climbs excessively.
We use gas heat but are considering a heat pump. Is that a practical choice for Mona's winters?
A modern cold-climate heat pump is a viable primary heat source for Mona. While our winter lows can challenge standard models, units with enhanced vapor injection (EVI) technology provide sufficient capacity down to below 0°F. Pairing it with your existing gas furnace as a dual-fuel system offers the highest efficiency and reliability. This setup uses the heat pump during milder weather and off-peak hours, then automatically switches to gas during the 2 PM to 8 PM utility peak or extreme cold, optimizing for cost and comfort.
We're told we need a new system. What efficiency standard applies now, and are there any rebates?
As of 2026, all new central air conditioners installed in Utah must meet a minimum 13.4 SEER2 rating. Modern units often exceed 18 SEER2, offering significant savings against Mona's average 11-cent per kWh rate. The federal Inflation Reduction Act provides an active rebate with an $8,000 income-based cap, which, when combined with the $400 Rocky Mountain Power Wattsmart rebate, can make a high-efficiency upgrade surprisingly affordable.
Our home's original AC unit is still running. What's the typical lifespan for a system in Mona?
The average home in Mona was built around 2001, so a 25-year-old system is operating well beyond its 12-15 year design life. At this age, the galvanized steel ductwork and fiberglass duct board are often compromised, allowing dust infiltration. This dust, combined with our hard water, directly causes the evaporator coil scaling we frequently diagnose. This scaling acts as an insulator, drastically reducing cooling capacity and efficiency.
What are the permit and safety requirements for installing a new AC unit in Juab County?
All HVAC replacements in Mona require a permit from the Juab County Building Department to ensure compliance with current mechanical and electrical codes. As of 2026, new systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety protocols: the install must include a refrigerant leak detector, follow new clearance requirements for wiring, and use certified recovery equipment. Only EPA Section 608 certified technicians holding the new A2L specialty designation can legally handle this refrigerant.
Can our current duct system handle a better air filter for wildfire smoke and spring pollen?
Your existing galvanized steel and fiberglass duct board system presents a static pressure challenge. While upgrading to a MERV-13 filter is excellent for capturing PM2.5 from wildfires and May pollen peaks, it can restrict airflow in older ductwork. A technician must perform a static pressure test before installation; often, sealing leaks and adjusting the blower speed is necessary to prevent strain on the motor and maintain proper delta T across the coil.
Why does our AC struggle to keep the house below 80°F when it's only 93°F outside?
Your system's design temperature is 93°F, meaning it is sized to maintain a 20-degree delta T (indoor temp of ~73°F) at that specific outdoor condition. When outdoor temperatures exceed this design point, capacity drops. Furthermore, evaporator coil scaling from hard water and dust, common here, exacerbates the issue by hindering heat absorption. Modern systems using R-454B refrigerant maintain better capacity and efficiency at these higher temperatures compared to older R-22 units.
