FAQs
If our air conditioning fails on a hot afternoon, how quickly can a technician arrive?
For a no-cool emergency in Downtown Greenwood, a technician can typically be dispatched from near Greenwood City Hall and reach most homes via M-24 within 10-15 minutes. We prioritize these calls to prevent heat buildup and potential system damage. Having your system's make and model ready when you call helps us prepare the correct tools and parts.
Our Ecobee thermostat is showing an 'E4' alert. What does that mean?
An Ecobee E4 code specifically indicates the thermostat has lost communication with your HVAC equipment's control board. In Greenwood, this often points to a wiring issue at the indoor unit, a tripped safety switch, or a failing control board itself. It's a signal to power down the system at the breaker and call for service. It prevents the system from running incorrectly and causing further issues.
Why does our air conditioner seem to struggle on the hottest days?
HVAC systems are sized for a specific design temperature, which in Greenwood is 88°F. When outdoor temperatures exceed this, the system must run continuously to try and meet the setpoint, reducing its effective capacity. The newer R-454B refrigerant standard for 2026 offers slightly better high-temperature performance than older refrigerants, but proper sizing and shade remain critical for handling peak heat.
Our home's original HVAC system is still running. Should we be concerned?
Greenwood homes built around 1985 have HVAC systems now over 40 years old. Units of this age operate at much lower efficiencies than modern standards, and their internal components, like seals and valves, degrade. This age is a primary reason condensate line freezing becomes common, as older systems often struggle to maintain proper refrigerant charge and airflow. Proactive replacement avoids a complete failure during peak demand.
What are the rules for installing a new air conditioner in 2026?
All installations require a permit from the Greenwood City Building Department. The 2026 codes mandate specific safety protocols for systems using A2L refrigerants like R-454B, which are mildly flammable. This includes leak detection, revised electrical clearances, and special labeling. Using a licensed contractor ensures compliance with these standards and validates manufacturer warranties and rebate eligibility.
Can our existing ductwork support better air filters for ozone and pollen?
Galvanized steel ductwork, common in Greenwood homes, is generally robust. However, installing a high-MERV filter, like a MERV-13 for May pollen peaks and ozone risk, requires a static pressure check. An undersized duct system or a blower not designed for the increased resistance can reduce airflow and strain the system. A technician should measure static pressure before upgrading filtration.
Is switching from our gas furnace to a heat pump a good idea here?
For Greenwood, with winter lows around 15°F, modern cold-climate heat pumps are a viable primary heat source. The economics depend on your gas versus electricity rates and the $8,000 federal rebate for qualified heat pump installations. To maximize savings, pair the heat pump with a smart thermostat to avoid running it during Consumers Energy's peak rate hours from 2 PM to 7 PM.
What does the new 13.8 SEER2 minimum efficiency standard mean for my electricity bill?
The 2026 SEER2 mandate ensures new systems use significantly less energy than older models. For Greenwood's average rate of $0.18 per kWh, upgrading from a pre-1992 unit to a modern 16+ SEER2 system can cut cooling costs by nearly half. The active Inflation Reduction Act rebates, with caps up to $8,000, can dramatically offset the upfront cost, making high-efficiency upgrades financially practical.
