Question Answers
What are the rules for installing a new AC system in Randolph County?
All new installations require a permit from the Randolph County Building Department. As of 2026, systems using A2L refrigerants like R-454B must comply with updated safety standards, including leak detectors, revised clearance distances, and specific labeling. These codes ensure the safe handling of mildly flammable refrigerants. We handle the permit process and ensure the installation meets all current EPA and local requirements.
What should we do if the AC stops cooling during a Union Center summer day?
First, check the thermostat settings and the circuit breaker for the outdoor unit. If those are correct, a technician can typically be dispatched from the Union City Public Library area to your home in under 15 minutes via IN-28. A common cause is a failed capacitor, which we can often diagnose and replace on-site to restore cooling quickly. Emergency service prioritizes restoring function to prevent heat stress on the system.
Can we improve indoor air quality for ozone and pollen without hurting our system?
Yes, addressing Union's ozone risk and May pollen peak requires a two-part strategy. First, a high-efficiency air filter like MERV-13 is effective. However, your existing galvanized sheet metal and fiberglass duct board system must be assessed for static pressure. We perform a pressure test to ensure the blower motor can handle the added resistance without reducing airflow or causing premature failure.
We have gas heat. Should we consider switching to a heat pump?
For Union homes, a dual-fuel system pairing a heat pump with your existing gas furnace is often optimal. The heat pump handles moderate cooling and heating efficiently, especially during off-peak hours outside the 2-8 PM window. During extreme cold below its balance point, the system automatically switches to gas heat. This hybrid approach leverages the strengths of both fuels, maximizing comfort and minimizing operating costs.
Our Ecobee thermostat is showing an 'E1' alert. What does this mean?
An Ecobee E1 code indicates the thermostat has lost communication with your HVAC equipment. In Union, this is often caused by a safety lockout on the furnace control board due to a recurring issue, such as a dirty flame sensor on your gas system or a failed pressure switch. It signals the system has stopped to prevent damage. A technician will diagnose the root cause at the furnace to clear the fault and restore operation.
Our central air system seems to be failing. Could its age be a factor here in Union?
For a typical Union home built around 1991, your original HVAC system is approximately 35 years old. This age places it well beyond its expected service life. The humid continental climate, with its seasonal moisture cycles, accelerates oxidation of the aluminum condenser coil, a primary failure point. Internal components like capacitors and contactors also degrade, making the system less reliable and more expensive to operate.
Is it worth upgrading our old AC unit to meet new efficiency standards?
The 2026 federal minimum is 13.4 SEER2, but modern systems in Union can achieve 17 SEER2 or higher. At a local rate of $0.14 per kWh, the energy savings are significant. The active Inflation Reduction Act (HEEHRA) rebates, with an $8,000 cap, combined with Indiana Michigan Power's $200-$500 incentives, often make the net cost of a high-efficiency upgrade comparable to a basic replacement.
How do our local summer temperatures affect air conditioner performance?
Union's design temperature for cooling is 89°F. When actual temperatures exceed this, as they often do, the system must run continuously to maintain setpoint, reducing its effective capacity. Modern units using the new R-454B refrigerant maintain better efficiency and pressure stability in this high-heat, high-humidity environment compared to older R-410A systems, providing more consistent cooling on the hottest days.
