Your Pelahatchie Heating and Cooling Experts
R-410A refrigerant — the standard in residential AC systems installed from the mid-2000s through 2024 — is being phased out under EPA regulations, with new systems now required to use lower-GWP refrigerants like R-454B. For Pelahatchie homeowners with existing R-410A systems, this creates a planning consideration: refrigerant availability and pricing for older systems will change over the next several years. Rankin County homeowners whose AC systems are approaching the 10 to 15 year mark should factor refrigerant transition costs into their repair-versus-replace analysis.
Rankin County's hot, humid summers keep AC systems running for 7 to 9 months of the year. High dew points accelerate biological growth in drain pans and evaporator coils — condensate drain flushing and coil cleaning aren't optional in Pelahatchie, they're how systems stay functional through the full cooling season.
Pelahatchie averages approximately 2,520 cooling degree days annually and sees around 64 days above 90°F each summer. The median home in Rankin County was built around 1977, meaning a substantial share of local air conditioning systems are approaching or past their typical 12 to 18 year service life.
