Common HVAC Problems And How To Address Them

Heating, Ventilation, and Air Conditioning (HVAC) systems are essential for keeping our homes comfortable throughout the year. However, like any system, they can experience problems from time to time. Understanding common HVAC issues and how to address them can save you time, money, and frustration. Rooter Hero Plumbing & Air of Sacramento looks at some of the most frequent problems, what to do about them, and when to contact an Best HVAC company in Sacramento.

1. Dirty Filters

One of the most common HVAC problems is dirty or clogged filters. Filters help trap dust, dirt, and other particles, keeping your air clean. However, over time, they can become dirty, restricting airflow and making your system work harder than it needs to.

Solution: To fix this problem, check your filters every one to three months, depending on the type of filter you use and the conditions in your home. If your filter looks dirty, replace it. Regular filter changes are a simple task that can significantly affect how well your HVAC system performs. If you’re unsure about which type of filter to use, a trusted HVAC company in Sacramento can help guide you.

2. Thermostat Issues

Sometimes, the problem isn’t with the HVAC system but the thermostat that controls it. If your HVAC system isn’t turning on or the temperature feels off, your thermostat might be the issue.

Solution: First, check if your thermostat is set to the correct mode (heating or cooling) and the temperature is set correctly. Changing the batteries could solve the problem if it’s a battery-powered thermostat. If it’s still not working, there could be a wiring issue or a problem with the thermostat’s sensors. In this case, you may need to contact an HVAC company in Sacramento for professional assistance.

3. Leaky Ducts

Ductwork is responsible for carrying heated or cooled air throughout your home. Over time, ducts can develop leaks due to wear and tear, or they may not have been adequately sealed in the first place. Leaky ducts mean your HVAC system has to work harder to heat or cool your home, leading to higher energy bills.

Solution: Inspecting your ducts for visible leaks or tears can help you identify the problem. Sealing minor leaks with duct tape or specialized sealants can improve your system’s efficiency. However, if you’re unsure or unable to reach the ducts yourself, a professional from an HVAC company in Sacramento can inspect your system and fix the leaks.

4. Refrigerant Leaks

Refrigerant is the chemical that cools the air in air conditioning units. If your air conditioner isn’t cooling correctly, it could be due to a refrigerant leak. Low refrigerant levels mean your air conditioner won’t be able to cool your home efficiently, and the leak could damage the system over time.

Solution: A professional should always handle refrigerant issues, as handling these chemicals requires specialized training and equipment. A certified HVAC technician can find the source of the leak, repair it, and recharge your system with the correct amount of refrigerant.

5. Frozen Evaporator Coils

Evaporator coils are part of the air conditioner that absorbs heat from the air in your home. However, if the coils freeze, they can’t do their job correctly, and your air conditioner will stop cooling efficiently. Frozen coils can result from dirty filters, blocked vents, or low refrigerant levels.

Solution: If you notice your air conditioner isn’t cooling well and suspect frozen coils, turn off your system to allow the coils to thaw. Check and replace dirty filters and ensure your vents are open and unblocked. If the problem persists, contact a professional HVAC company in Sacramento to diagnose and repair the issue.

6. Pilot or Ignition Problems

For systems that use gas for heating, problems with the pilot light or ignition system can prevent the furnace from working correctly. Dirty components, faulty sensors, or problems with the gas supply could cause these issues.

Solution: If comfortable, inspect the pilot light or ignition system for dirt and clean it gently. However, because this involves handling gas, it’s often best to let a professional HVAC technician take a look. They can safely identify and fix the problem, ensuring your home stays warm during the colder months.

7. Unusual Noises

Unusual noises from your HVAC system, such as banging, rattling, or squealing, often indicate something is wrong. Loose parts, motor issues, or worn-out belts could cause these noises.

Solution: While some minor issues can be addressed by tightening screws or replacing belts, it’s often wise to have a professional inspect your system to ensure there’s not a more serious underlying problem. An HVAC company in Sacramento can help pinpoint the cause of the noise and make the necessary repairs.

8. Short Cycling

Short cycling happens when your HVAC system turns on and off too frequently. This can occur if your system is too large for your home, your thermostat is malfunctioning, or there’s an airflow issue.

Solution: Check your thermostat settings and filters to rule out simple problems. If the short cycling continues, contact an HVAC professional to assess whether your system is the right size for your home or if a more complex issue is at play.
