Common Questions
What does a standard plumbing inspection from Coastal Air Plus include?
Our comprehensive plumbing inspection is designed to give North Charleston homeowners peace of mind. We systematically check for leaks, test water pressure, inspect visible pipes for corrosion, assess the condition of fixtures like faucets and toilets, and evaluate your water heater's performance and safety. For homes in our area, we pay special attention to drainage systems, which can be affected by our local soil and humidity. The goal is to identify small issues before they become major problems, helping you save on water bills and prevent costly damage.
My AC unit keeps turning on and off frequently (short cycling). What could be causing this in my North Charleston home?
Short cycling is a common issue here, often caused by our high humidity and salt air. It can stem from an oversized unit, a dirty air filter restricting airflow, low refrigerant levels, or a faulty thermostat. More specifically for our coastal climate, corrosion on electrical components within the outdoor unit from salty air can also trigger this problem. Our technicians are trained to diagnose the root cause—whether it's a simple filter change, recharging refrigerant, cleaning corroded connections, or assessing if your system is properly sized for your home.
Does Coastal Air Plus offer financing for new HVAC system installations?
Yes, we offer flexible financing options to help make new, energy-efficient heating and cooling systems more manageable for your budget. We provide free, no-obligation estimates so you know the exact cost upfront. Our team can then discuss various financing plans that work for you, allowing you to invest in a reliable system that improves your home's comfort and efficiency without a large upfront payment. This applies to both residential and commercial projects.
