Troubleshooting Tips for Your HVAC System
Like most modern equipment, your HVAC unit is a sophisticated system with many intricate components. It can develop faults due to wear and tear or poor installation, among other factors, but you can troubleshoot your system by following these tips.
Reset Your HVAC System
If your HVAC system isn’t working, you can try running a reset. Modern models have complex circuitry, and you can resolve many issues by rebooting your system. The purpose of the reset button is to prevent overheating and explosions. If there has been a power outage and your HVAC unit isn’t working, resetting it is one way to resolve the issue.
You may also use the reset if your air conditioning unit blows warm air. Sometimes, the issue is caused by a thermostat glitch. Restarting the equipment can often correct the error, restoring the cooling function of your HVAC system.
Start by switching off your unit at the shut-off panel. Next, turn off the power at the circuit breaker. Locate the reset button, which is typically red. Hold it for a few seconds and switch it back on. Your HVAC system should start.
Troubleshoot the Thermostat Before Other Parts
When troubleshooting complex systems such as your HVAC unit, you should rule out the simplest and most obvious causes. You can start by checking the power supply and resetting your system.
The thermostat is another component you should rule out before making any conclusions. An incorrect setting or device malfunction can cause noticeable changes in performance.
One of the problems your thermostat may cause is frequent cycling. Check the thermostat settings and ensure they’re correct. It’s also possible that the device requires recalibration.
Dust and debris can affect the temperature readings. If the device is registering incorrect temperatures, its performance will be erratic. You can use a soft cloth or a blower to remove grime on the thermostat.
If your HVAC system is still not working, it might be an issue with the thermostat’s location. When this device is in direct sunlight or near heating equipment, it may register wrong readings. Moving the device to a different location can fix the problem.
Last but not least, it could be that the thermostat is faulty and needs to be repaired or replaced. But first, check the batteries and replace them if necessary. If that fails, you can consult an HVAC repair technician to troubleshoot and fix the problem.
Anywhere in the Phoenix or Scottsdale areas, skilled technicians from Champion Air would be happy to help. An efficient thermostat is critical for the performance of your heating and cooling system.
Check for Airflow Obstructions
An imbalance in airflow is a common problem affecting an HVAC system’s function. Obstructions can prevent your HVAC unit from pulling or pushing air into the interior.
When there are airflow imbalances in your HVAC system, you’ll notice these symptoms. Contact us for prompt repairs.
- Hot and cold spots throughout the house
- The AC blowing warm air
- No air or low airflow from the vents
- Whistling noises from the system
With air imbalances, clogged filters are among the most common culprits. Changing or cleaning your filter at least once a month can keep your HVAC system running efficiently.
You should also check your outdoor unit for blockages. Leaves and debris can accumulate around the equipment. Such obstructions will overwork your system, reducing its life span considerably.
The air in your home comes through the vents on the floor or ceiling. Blockages on the vents prevent air from circulating and regulating temperatures in your home. Consequently, you should check all the vents and make sure there are no obstructions.
Switch Off the AC To Thaw Ice
One problem you may encounter during the summer is ice accumulating on the outdoor unit. Several factors can cause frost to develop. It could be airflow problems, a broken motor, grime on the evaporator coil, or low refrigerant levels.
If there’s frost on the outdoor AC unit in summer, the first step is to switch your AC off. Keep the fan on to let warm air pass over the condenser and thaw the ice. If your air conditioner is still not working after this, it might be an issue with airflow.
Check for airflow imbalances by removing obstructions around the vents. If the issue is a dirty coil or low refrigerant level, you’ll have to call an HVAC professional. Only a certified technician has the skills and tools to clean coils and recharge the refrigerant safely.
A faulty motor will limit cool air from getting into the interior. You’ll have to replace the component to prevent further damage to the system. You can rely on the experts from Champion Air for a thorough assessment of your equipment.
Inspect Your Ductwork
You should also take the time to inspect your ductwork for blockages and leaks. If there are punctures in the air ducts, these can pull air in from the outside or let conditioned air escape. Dust and even toxic fumes could start circulating in your home, or your utility bills could rise sharply.
One sign of faulty ductwork is when there are rooms that never seem to heat up sufficiently. If you turn on your furnace, the different parts of your home should heat up almost simultaneously. Your heating system will also have to work harder to keep the interior comfortable. Experts suggest that typical ductwork can lose between 20% and 40% of the energy it consumes.
One way to prevent leaks and blockages is to regularly schedule duct cleaning and sealing. Your ductwork has a life span of between 10 and 15 years. If your air ducts are over 15 years old, they might need a replacement. Contact Champion Air about duct cleaning or sealing.
DIY Maintenance Checklist for Your HVAC System
Maintaining your HVAC system is essential for ensuring its longevity and efficient operation. Regular maintenance can prevent costly repairs and extend the life of your system.
Here are some simple DIY maintenance tasks homeowners can do to keep their HVAC system in top shape:
- Changing the air filter: One of the easiest and most crucial tasks is changing your air filter regularly. A clogged or dirty filter restricts airflow, making your HVAC system work harder. Check the filter every one to three months, and replace it when it looks dirty or clogged.
- Cleaning & clearing debris: The outdoor condenser unit can become clogged with leaves, grass, and other debris, obstructing airflow. Periodically clear away debris from around the unit to ensure proper ventilation.
- Checking indoor vents: Make sure indoor supply and return vents aren’t blocked by furniture, curtains, or other obstructions. Restricted airflow can strain your system.
- Inspecting & clearing the condensate drain: Check and clean the condensate drain to prevent clogs, which can lead to water damage or mold growth.
- Scheduling annual maintenance: Schedule annual professional HVAC maintenance. A certified technician can perform a thorough inspection, clean components, and make adjustments to optimize performance and efficiency.
By following these DIY maintenance tasks and keeping your HVAC system in good condition, you can save on energy costs, enhance indoor comfort, and extend the life span of your system.
When To Call an HVAC Professional
You can address some problems by troubleshooting parts of your system. You can reset the thermostat and change the filter if your equipment isn’t functioning correctly. But when it comes to technical issues, it’s best to leave the complicated repairs to a professional.
Your HVAC system is an essential investment for your home’s comfort and safety, and you can damage components by trying to repair it yourself. There’s also the risk of electric shock or exposure to toxic refrigerants.
Fixing parts of your AC can also void your manufacturer’s warranty. That’s why you should always consult certified professionals with experience fixing HVAC systems. Some components can be expensive to replace. By upholding your warranty, you can eliminate unnecessary repair costs.
