Plumbing & Drain Cleaning 

  • How do I know if my main sewer line is clogged or backing up?

    Common signs of a clogged main sewer line include multiple plumbing fixtures backing up simultaneously (e.g., water rising in the bathtub when flushing the toilet), bubbling noises from drains, foul sewage smells, or standing water near your outdoor cleanout. 


    Recommended Action: 


    1. Stop running water immediately to prevent sewage overflow inside your home. 
    2. Locate your outdoor sewer cleanout (if accessible). 
    3. Contact ABC Plumbing at (209) 334-2938 for professional main line clearing or camera inspection. 
  • What is hydro jetting, and when is it necessary?

    Hydro jetting is an advanced pipe-cleaning method that uses high-pressure water streams (up to 4,000 PSI) to scrub grease, mineral scale, sludge, and tree roots from sewer lines. It is recommended for persistent line blockages, commercial kitchens, and older residential pipe infrastructure that standard cabling cannot fully restore.

  • Why is my water heater leaking or not heating properly?

    No hot water or active leaks are commonly caused by broken heating elements, a failed thermostat, sediment accumulation inside the tank, or a failing pressure relief valve. If water pool around the base, the tank itself may be rusted or cracked, requiring replacement. 


    Types of Water Heaters We Repair & Replace: 


    Standard Tank: Gas and electric water heaters. 


    Tankless: On-demand high-efficiency units. 


    Specialty Units: Ceiling-mounted electric water heaters. 

Heating & Air Conditioning (HVAC) 

  • Why is my air conditioner blowing warm air?

    An air conditioner blowing warm air is typically caused by a dirty air filter blocking airflow, frozen evaporator coils, a refrigerant leak, or a failing compressor/capacitor. Before calling a technician, verify that your thermostat is set to "COOL" and the air filter is clean.

  • How often should I replace my HVAC filter and schedule maintenance?

    Air filters should be changed every 1 to 3 months, depending on pet ownership and indoor air quality needs. Professional HVAC maintenance should be scheduled twice a year: once in spring for your air conditioner and once in autumn for your furnace/heating system.

  • Should I repair or replace my aging HVAC unit?

    Replace your HVAC unit if it is over 12–15 years old, requires frequent costly repairs, or causes escalating energy bills. If repair costs exceed 50% of a new system's price, upgrading to a modern energy-efficient heat pump or A/C unit will lower operating expenses and improve home comfort.
