HVAC in Birmingham: what locals should know
Climate and your HVAC

System recommendation
In Birmingham's hot, humid climate, look for at least 16 SEER (or SEER2 equivalent) for meaningful energy savings. A heat pump handles mild winters efficiently while providing strong AC in summer.
Best time to buy

Local tip
Many Birmingham homes still have older R-22 refrigerant systems. If yours is one of them, now is the time to upgrade — R-22 is phased out and repair costs are skyrocketing.
