Before you place a call for 24-hour emergency service in Richmond, TX, there are a few checks you can perform as a Richmond homeowner. First, locate the emergency float switch, which is positioned beneath your air conditioning unit inside the emergency drain pan. You should also check for emergency safety sensors within your PVC pipes. Sometimes, you may notice low voltage wires connected to the white PVC pipes. If your PVC pipes are not draining correctly, your AC unit may shut off. If you have a vacuum cleaner that can remove water, you can use it to clear any blockages from your pipes. The easiest access point for vacuuming your PVC pipes is typically on the exterior of your home, near your condensing unit. In some cases, it may be under your bathroom sink. Additionally, you may not need service in Richmond Tx 77406 if you check your circuit breakers first. In hot weather, circuit breakers can trip, and this doesn’t always indicate a problem with your HVAC unit. Sometimes, a breaker trips simply because it’s failing. You might also want to consider maintenance for your outdoor unit. A dirty condenser can cause your system to overheat, leading to excessive amperage draw. Regularly washing your unit with a hose can help it operate more efficiently and with less stress.
