A clogged condensate drain is the most frequent culprit, though a frozen coil or a cracked drain pan can also be the cause. Switch the system off and call us to avoid water damage.
As a rule of thumb, equipment past 10 to 15 years that needs frequent repairs or still uses older refrigerant is usually a better candidate for replacement. Newer systems with a minor fault are normally worth repairing.
Proper sizing depends on square footage, insulation, windows, ceiling height and local climate. We calculate the load rather than guess, because oversized and undersized units both waste energy.
Keep filters clean, seal air leaks, use a programmable thermostat and book a yearly tune-up. If your equipment is old, an efficient replacement can make a bigger difference.
