Read on to learn how to maintain home HVAC system and ensure your family’s comfort and safety all year round.

#1. Eliminate Clutter Around the Indoor HVAC Unit

One simple way to maintain your HVAC system is by keeping the area around the indoor unit clear of clutter. This means removing items stored near the unit, like boxes, clothes, or other items. Doing this improves air quality inside your home and ensures your HVAC system functions efficiently.

When there is clutter around your indoor HVAC unit, it can cause several issues. For one, it can reduce the air quality inside your home. The more items you have near the unit, the more surface area to collect dust, which can enter the vent system. This can cause respiratory issues for those living in the home and exacerbate allergies or other health concerns.

Furthermore, clutter can block air circulation, reducing system efficiency and increasing energy bills. When your HVAC system works harder than it needs to, it strains the system, leading to breakdowns and expensive repairs.

Keeping the area around your indoor HVAC unit clear prevents these issues and ensures your HVAC system functions at its best. This will save you money on energy bills and improve air quality in your home, promoting a healthier living environment.

#2. Keep the Outside Unit Clean and Clear

The outdoor HVAC unit is an integral part of your HVAC system and is exposed to weather elements year-round. Debris, like leaves, twigs, and grass clippings, can accumulate on the outside unit and reduce airflow. This can cause strain on the system, leading to increased energy bills and potentially damaging the unit. 

Maintaining your HVAC system by regularly cleaning the outside unit and ensuring it is clear of debris is crucial. You can do this by removing any debris that has accumulated on or around the unit and using a hose to wash it down. Also, it is vital to trim nearby plants back at least two feet from all sides of the unit to allow proper airflow.

By keeping the outside unit clean and clear, you improve the efficiency of your HVAC system and extend its lifespan.

#3. Change the Filters

Air filters are an essential part of any HVAC system. They play a crucial role in preventing dust, pet hair, pollen, and other particles from circulating throughout your home. Dirty air filters can clog your HVAC system and make it work harder than it should, leading to a shorter lifespan and higher energy bills. To prevent this, it’s recommended to change your air filters every 30 days is recommended. 

This not only improves your indoor air quality but also makes your HVAC system run more efficiently. When choosing a filter, aim for a MERV rating between 7 and 13. This range strikes the perfect balance between airflow and filtration efficiency. Don’t forget to turn off your HVAC system before changing the filter and dispose of the old filter properly.

#4. Perform a Visual Inspection of the HVAC System

In addition to changing the filter, perform a visual inspection of the HVAC system every month. This inspection will help you uncover potential problems before they turn into major issues. Start by checking the thermostat to ensure it is working correctly and is set to the right temperature. If you notice any issues, call an HVAC contractor in Central, CT to inspect the thermostat and fix any problems.

Next, inspect the indoor and outdoor units. Look for signs of damage, like cracks, rust, or loose components. Check the air registers and return grilles to ensure they are clean and unobstructed. A dirty or blocked register can reduce airflow and strain the system, leading to increased energy bills and potential damage to the unit.

If you have a condensate drain, inspect it to ensure it drains correctly. A clogged or blocked drain can lead to water damage, mold growth, and system failure. Ensure filter access and cabinet door are securely closed and the flue system is securely attached and fully intact. Also, check for signs of mold on registers or other components.

#5. Regulate Your Home Temperature

It’s important to regulate your home temperature to ensure your system is not overworking itself. One way to do this is by installing a programmable thermostat. With a programmable thermostat, you can set different temperatures for different times of the day. For example, during the summer, you can set the temperature higher during the day when you’re not at home and lower at night when you sleep. In the winter, you can set the temperature lower when you’re away and higher when you’re home. 

This reduces the workload on your HVAC system, which can help prolong its lifespan and lower your energy bills. Plus, it’s a great way to save money and energy without sacrificing comfort.

#6. Change the Batteries in Your Thermostat

Many thermostats are powered by batteries, and it is crucial to replace them at least once a year to prevent any potential issues that could lead to system failure. Replacing the batteries regularly ensures the thermostat works correctly and accurately communicates with the HVAC system. It is wise to check the battery status periodically to ensure they are not low and to replace them promptly if they are. 

Keeping batteries fresh is a simple step to help prolong your HVAC system’s lifespan and prevent any unexpected breakdowns. 

#7. Maintain your Carbon Monoxide Detector

A carbon monoxide detector is an essential safety device in homes with heating systems that rely on combustion, like natural gas or fuel oil. Carbon monoxide is a colorless, odorless gas that can be deadly when inhaled in high concentrations. To protect your household from this dangerous gas, ensure your carbon monoxide detector is functioning correctly.

To maintain your carbon monoxide detector, test it monthly to confirm it is working correctly. This will detect any potential malfunctions or issues with the sensor, ensuring it alerts you in the event of high levels of carbon monoxide.

Additionally, replacing the batteries in the detector at least twice a year is vital to ensure it is always functioning correctly. It is recommended to replace batteries every six months to guarantee optimal performance.

If you suspect your carbon monoxide detector is not functioning correctly, it’s important to replace it immediately. Investing in a reliable and high-quality carbon monoxide detector is an important step in protecting your household from the dangers of carbon monoxide gas. By ensuring your detector is working correctly, you enjoy peace of mind and know your family is safe.
