Understanding Your HVAC System
Not all heating and cooling systems are the same. Knowing what type of system you have helps you understand how it operates, how it’s serviced, and what repair or replacement options make the most sense.
Common HVAC System Types
Whether your system is a split unit or a rooftop package unit, it can be either gas or electric. The terms “split” and “rooftop” describe where the equipment is located, not how it heats your home.
Split System
- The most common setup in homes
- Includes an outdoor condenser and an indoor unit (coil + furnace or air handler)
- Can be paired with gas heating or operate as a heat pump
Heat Pump System
- Provides both cooling and heating using electricity
- Transfers heat instead of generating it
- Popular in the Central Valley for energy efficiency and mild winters
Rooftop Package Unit
- All components are contained in a single unit, typically on the roof
- Common in commercial buildings and some residential homes
- Saves indoor space and simplifies duct connections
- Can be configured as gas + AC or as a heat pump
Gas + AC System
- Uses a gas furnace for heating and a separate AC system for cooling
- Reliable and powerful, especially in larger homes
Common Heating Issues
Not all heating problems mean your system has failed. Some issues are minor, while others can signal a larger concern. Understanding the most common heating issues can help you recognize when it’s time to take action and restore comfort to your home.
Brrr! If your furnace isn't producing heat, check the thermostat, air filter, and pilot light (if applicable). If those are fine, it's time for a professional diagnosis.
Constant on-and-off cycles often indicate airflow issues like a dirty filter or blocked ductwork. Addressing these can improve efficiency and comfort.
Rattling, banging, or screeching noises could signal worn belts, loose components, or faulty igniters. Ignoring these can lead to bigger problems down the line.
If your system is running but blowing cool or room-temperature air, the issue is often related to a misconfigured thermostat, a heat pump stuck in cooling mode, or a problem with the reversing valve or ignition system. In some cases, the system may be running the fan without producing heat, which is a sign it needs professional service.
Uneven heating or weak airflow points to potential problems like clogged ducts, dirty filters, or malfunctioning blower fans. Regular maintenance can prevent these issues.
Burning smells can indicate electrical problems, while oily odors might suggest overheating components. Both warrant immediate professional attention.
If some rooms feel warm while others stay cold, your system may not be distributing air evenly. This can be caused by duct issues, airflow restrictions, or system sizing problems. A professional inspection can help restore balanced comfort throughout your home.
A sudden increase in heating costs often means your system is working harder than it should. Dirty components, airflow problems, or aging equipment can reduce efficiency. Addressing the issue early can help lower energy use and prevent further wear.
