Frequently Asked Questions
What should I do if my air conditioner stops working on a hot day?
First, check your thermostat settings and the circuit breaker. If the system remains off, a technician can typically reach the Stony Point Residential District from the office near the park in 15-20 minutes via M-125. For a no-cool emergency, common culprits include a tripped safety switch from a frozen evaporator coil or a failed capacitor, both of which we carry on our service trucks.
Does switching from a gas furnace to a heat pump make sense for our winters?
For Stony Point, a cold-climate heat pump is a viable primary heat source, especially when paired with the existing gas furnace as a dual-fuel or backup system. The economics improve by using the heat pump during off-peak hours, avoiding the 2 PM to 7 PM utility peak, and leveraging the substantial federal rebates for electrification projects.
Why does my AC struggle to keep the house cool during the hottest summer days?
Michigan design temperatures for cooling are based on a 88°F outdoor dry-bulb temperature. When actual temperatures exceed this, the system's capacity drops. Modern R-454B refrigerant systems are engineered for better high-temperature performance and capacity retention compared to older R-22 units, helping to close that performance gap during our occasional extreme heat.
Can my home's duct system support a high-efficiency air filter for allergies?
Galvanized steel ductwork, common in Stony Point, is generally robust but may have restrictive older designs. Installing a MERV-13 filter to capture May pollen and mitigate ozone-related particulates requires a static pressure check. An unbalanced system with high static pressure can reduce airflow, strain the blower motor, and diminish both comfort and efficiency.
Is there a good reason to replace my old AC before it completely fails?
Yes, the 2026 federal minimum efficiency standard is 13.4 SEER2, which is significantly higher than units installed 20 years ago. Upgrading now leverages the active HEEHRA rebates, which can cover up to $8,000, directly offsetting the cost. Pair this with DTE Energy's $200-$500 efficiency program, and the upgrade reduces your energy use against the local $0.18 per kWh rate, improving payback.
My Ecobee thermostat is showing an E1 error code. What does that mean?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Stony Point homes, this is often caused by a safety lockout on the furnace control board due to a recurring issue, such as a flame sensor fault on your gas system or a condensate overflow switch. It signals the need for professional diagnosis to prevent a complete system shutdown.
What are the permit and safety requirements for a new AC installation?
All HVAC replacements in Stony Point require a permit from the Stony Point Building & Inspection Department. Since 2023, new systems using A2L refrigerants like R-454B must comply with updated safety standards (UL 60335-2-40). These mandate specific leak detection, airflow verification, and equipment room requirements that certified technicians are trained to implement.
How long do HVAC systems typically last in older Stony Point homes?
The average system age in a 1968-built Stony Point home is 58 years. Units this old often operate on outdated R-22 refrigerant and suffer from corrosion in the galvanized steel ductwork. This age and the moderately humid environment make the condensate drain line particularly prone to freeze-ups and biological growth, which are leading causes of service calls here.
