Questions and Answers
Are there new permit or safety rules for installing a new AC unit in 2026?
Yes. All new installations using A2L refrigerants like R-454B must follow updated 2026 safety codes requiring leak detectors and updated electrical classifications. A permit from the Panola County Building and Permit Department is mandatory. This ensures the installation meets strict new standards for these mildly flammable refrigerants, which are now the industry standard.
Can my home's ductwork handle a high-efficiency air filter for Mississippi ozone and pollen?
Higher MERV-13 filters are excellent for capturing April pollen and fine particulates linked to ozone days. However, the flex duct and galvanized steel plenums in many Como homes create higher static pressure. Installing a filter this dense usually requires a system assessment to avoid overtaxing the blower motor, which can be solved with a properly sized media cabinet.
Why does my air conditioner struggle when it hits 98°F, if it's designed for 93°F?
Your system is engineered for a 93°F design temperature, a local building code standard. On days reaching 98°F, the capacity drops as it works against a higher temperature differential. Modern units using R-454B refrigerant maintain better efficiency and pressure stability in this extreme heat compared to older R-22 or R-410A systems, but some capacity loss is inevitable.
What's the new 2026 efficiency standard, and do the new rebates make an upgrade worthwhile?
The federal minimum efficiency is now 14.3 SEER2. Upgrading from an old 10 SEER unit to a new 18 SEER2 model can cut cooling costs by nearly 40%. Combined with Entergy Mississippi rebates and the active federal HEEHRA tax credit of up to $8,000, the net investment is often recovered in under five years at our local rate of $0.13 per kWh.
How old is my Como HVAC system likely to be, and what's the most common age-related failure?
Homes in Como average a 1977 build year, making many original or replacement systems close to 20 years old. At this age, refrigerant lines and electrical components degrade. The humid climate specifically accelerates algae and mold growth in the condensate drain line, which is the most frequent service call for older units here. A clogged drain can cause water damage and system shutdowns.
With electric heat, should I consider a heat pump for my Como home?
Yes, a modern cold-climate heat pump is a logical upgrade. While our winter lows are manageable for these systems, the key benefit is efficiency. During the 2 PM to 7 PM peak rate period, a heat pump provides heat at about one-third the cost of electric resistance strips. This shift significantly reduces your winter energy bill while providing year-round comfort from one unit.
If my air conditioner stops on a hot day near Como Town Square, how fast can a technician arrive?
For a no-cool emergency, our service trucks are typically dispatched from near I-55. From that location, we can reach most homes in Downtown Como within 5 to 10 minutes. We prioritize these calls to prevent heat buildup and humidity damage inside your home during our hottest hours.
My Ecobee thermostat is showing an 'E1' alert. What does that mean for my system?
An Ecobee E1 code indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Como, this often points to a safety lockout from a clogged condensate drain line—triggered by our humidity—or a failed control board. It's a diagnostic signal that prevents compressor damage and requires a technician to check the primary system controls.
