Frequently Asked Questions
My heat went out during a February cold snap. How fast can a technician get here?
For a no-heat emergency in Downtown Houghton, our dispatch uses Michigan Technological University and US-41 as central reference points. This allows us to route technicians efficiently around campus traffic and main arterial roads. Given these logistics and the density of service calls in the core, a technician typically arrives on-site within 5 to 10 minutes of dispatch confirmation to begin diagnostics on your natural gas furnace.
My furnace is original to my 1979 Houghton home. Should I be concerned?
A system from 1979 is now 47 years old. In Downtown Houghton's humid continental climate, galvanized steel ductwork from that era often develops internal corrosion. This corrosion, combined with decades of seasonal expansion and contraction, frequently leads to misaligned joints and disconnected condensate drain lines. When these lines detach in a damp basement, the resulting water leakage is a primary cause of the frozen condensate lines we commonly see on service calls.
What are the permit and safety requirements for a new AC installation in 2026?
All installations in Houghton require a permit from the City of Houghton Building & Zoning Department. As of 2026, systems using the mildly flammable A2L refrigerant R-454B must adhere to updated safety standards. These include specific clearance distances from ignition sources, mandatory leak detectors in confined spaces, and special labeling. Only EPA Section 608 certified technicians with the new A2L safety training endorsement are legally permitted to handle this refrigerant.
Can my home's HVAC system filter out wood smoke and spring pollen?
Yes, but system compatibility is key. Wood smoke particulates and May pollen peaks require a MERV-13 filter for effective capture. Your existing galvanized steel ductwork, common in 1979 Houghton homes, is generally robust. However, installing a high-MERV filter can increase static pressure. A technician should measure your system's external static pressure to confirm it can handle the filtration upgrade without reducing airflow or straining the blower motor.
If Houghton's summer highs can reach the 80s, why is the AC design temperature only 85°F?
HVAC design temperature is based on a 1% exceedance calculation, meaning local equipment is sized to maintain comfort 99% of the time. While Houghton can experience peaks above 85°F, designing for a higher temperature would lead to chronic oversizing, poor humidity control, and short cycling. The newer R-454B refrigerant standard for 2026 improves high-ambient temperature performance slightly, but proper sizing remains the priority for efficiency and comfort.
Is a heat pump a realistic primary heat source here, given our cold winters?
Modern cold-climate heat pumps are engineered to provide efficient heat down to -15°F, making them viable for Houghton. The economic case involves analyzing your natural gas versus electricity costs. Since UPPCO's peak hours are 2 PM to 7 PM, a well-designed system with a properly sized backup heat source can minimize operation during those expensive periods. The $8,000 federal rebate substantially improves the financial argument for transitioning from natural gas.
My Ecobee thermostat is showing an 'E1' alert. What does that mean for my system?
An Ecobee E1 alert signals a communication failure between the thermostat and your HVAC equipment. In Houghton, this often points to a voltage issue caused by a tripped safety switch, such as a float switch in a clogged condensate line—a frequent problem in our humid climate. It can also indicate a failing control board or a wire damaged by temperature swings in the attic or basement. This alert prevents the system from running to avoid safety hazards.
What does the new 13.4 SEER2 minimum mean for my electricity bill?
The 13.4 SEER2 mandate for 2026 ensures new air conditioners and heat pumps use at least 20% less energy than many pre-2023 models. At Houghton's current rate of $0.18/kWh, this directly lowers summer cooling costs. When paired with the active Inflation Reduction Act rebate, which offers up to $8,000 for qualified heat pump installations, the payback period for upgrading an aging system becomes significantly shorter, improving both efficiency and economics.
