Q&A
What are the regulations for installing a new AC or heat pump?
All installations require a permit from the Comstock Township Building Department. Since January 2023, new systems must use lower-GWP A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards: leak detectors, revised service practices, and updated equipment markings. Only EPA Section 608 certified technicians with A2L-specific training can legally handle and install these units.
Our system is getting old. What's the main thing to watch for as it ages?
A typical Comstock home built around 1992 likely has a system approaching its 34th year. Aging galvanized ductwork with fiberglass liner can degrade, creating leaks that reduce airflow and efficiency. The most frequent service call we see in this age range is for a frozen and clogged condensate drain line, caused by restricted airflow or low refrigerant charge stressing the evaporator coil.
What should I do if my air conditioning stops working during a hot day?
First, check the thermostat settings and the circuit breaker for the outdoor unit. If those are correct, a technician can typically diagnose common failures like a failed capacitor or contactor on-site. From our service center near the Comstock Township Library, we can dispatch a truck via I-94 and reach most homes in Comstock Village within 10 to 15 minutes for an emergency no-cool diagnosis.
Should I consider switching from my natural gas furnace to a heat pump?
For Comstock homes, a dual-fuel system pairing a heat pump with a gas furnace is often optimal. The heat pump efficiently handles heating above 30°F, avoiding the 0.18/kWh cost during Consumers Energy's 14:00-19:00 peak hours. The gas furnace provides reliable heat during colder snaps, ensuring comfort and potential cost savings depending on the fluctuating price of natural gas versus electricity.
Can my current duct system handle a better air filter for pollen and dust?
Your existing galvanized sheet metal ducts with a fiberglass liner are structurally sound for upgraded filtration. However, installing a high-MERV filter, like a MERV-13 for capturing PM2.5 and May pollen, increases static pressure. A technician must measure your system's static pressure to ensure the blower motor can handle the restriction without reducing airflow or causing the evaporator coil to freeze.
Is the new SEER2 rating worth the investment with current electricity prices?
The 2026 federal minimum is now 13.4 SEER2, but modern systems often exceed 16 SEER2. At Comstock's rate of $0.18 per kWh, upgrading from a 10 SEER unit to a 16 SEER2 model can cut cooling costs by nearly 40%. The active Inflation Reduction Act rebate provides up to $8,000 at the point of sale for qualifying high-efficiency installations, making the payback period significantly shorter.
How well do new air conditioners handle our hottest summer days?
Michigan's humid continental climate presents a design challenge. Equipment is selected for a 87°F design temperature, but actual temperatures can exceed this. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-410A units, providing more consistent cooling and humidity control during peak heat.
My Ecobee thermostat is showing an E4 alert. What does that mean?
An Ecobee E4 code indicates the thermostat has lost communication with your HVAC equipment. In Comstock, this is commonly caused by a brief power interruption, a tripped safety switch on the furnace, or a failing control board. It signals the system has shut down to prevent damage. Resetting the breaker may clear it, but a persistent E4 requires a technician to check for wiring issues or component failure.
