Concerned about the hard water in North San Diego County? We offer comprehensive water filtration and purification systems to ensure your tap water is clean, safe, and tastes great.
Because of the salt air and humidity in coastal North County, we recommend professional HVAC maintenance twice a year (Spring and Fall) to prevent corrosion and maintain efficiency.
Common signs include an unexplained spike in your water bill, damp spots on floors/walls, or the sound of running water when all faucets are off. If you suspect a leak, contact our Oceanside leak detection experts immediately.
The salt air and high humidity in North County are highly corrosive to standard HVAC units. Salt deposits can eat away at aluminum fins and copper coils, leading to refrigerant leaks and a lifespan reduced by up to 50%.
