Seasonal HVAC Maintenance Checklist

An integral part of taking care of your home or office is keeping your heating, ventilation and air conditioning (HVAC) system in proper working order. Regular seasonal maintenance of all of its components not only helps to extend their life, but also helps to significantly improve the efficiency of the equipment. This is important not only for comfort, but also for saving money on energy bills. Timely furnace maintenance and tune-ups, regular heater inspections and repairs ensure that your home maintains an optimal climate year-round.

Spring Maintenance Tips

Spring is the perfect time to perform seasonal maintenance on your HVAC system. To keep your home or office running smoothly and comfortable, it's important to prepare your equipment for the upcoming summer season after the cold winter months.

What are your spring HVAC system maintenance tasks?

Air conditioner inspection and cleaning

  • Before the summer heat arrives, make sure your air conditioner is ready for heavy use. Start with the outside unit - remove dust, dirt, and any foreign objects that may have accumulated over the winter. This will improve airflow and increase the efficiency of the system.

Filter Replacement

  • Changing filters regularly is one of the easiest and most effective ways to keep your HVAC system in good condition. Dirty filters reduce its efficiency, increase the strain on your equipment and can lead to breakdowns. It is recommended to change filters every 1–3 months, depending on the operating conditions.

Checking the air ducts for leaks

  • Ducts, an important part of the entire system, ensure that air is distributed evenly throughout your home. Over time, they can develop leaks, resulting in wasted energy and reduced equipment efficiency. Check your ductwork for cracks and gaps, and seal them with special sealing tape or mastic if necessary.

Performing these tasks regularly will help you avoid unexpected problems and keep your HVAC system running smoothly throughout the spring and summer season.

Summer Maintenance Tips

Summer can be humid and hot, so it's important to make sure your HVAC system is ready for the intense heat. Preparing it for the summer heat includes a number of key tasks that will help keep your home at a comfortable temperature and avoid debilitating heat.

Regularly checking for refrigerant

  • Refrigerant plays an important role in the operation of an air conditioner. A lack of refrigerants will cause the air conditioner to lose efficiency and possibly break down. Contact a professional technician who will check the coolant level, replenish it if necessary, identify and repair any leaks.

Thermostat Setting

  • Proper thermostat settings not only ensure that your thermostat maintains a comfortable temperature, but also saves a significant amount of energy. Make sure the thermostat is working properly and is set to the optimal temperature for summer. Consider installing a programmable thermostat, which will allow you to automatically adjust the temperature based on the time of day and your schedule.

Checking the condition of the insulation

  • Flawless condition of your air conditioner pipes and ducts keeps your home consistently cool and reduces the strain on your HVAC system. Check the condition of their insulation. If the pipe insulation is worn or damaged, replace it. By doing so, you will prevent cold air leaks and improve the energy efficiency of your system.

These tips will help you prepare your HVAC system for summer loads and keep it running smoothly.

Fall Maintenance Tips

Fall is the time to prepare your HVAC system for the upcoming winter. To ensure comfort and safety during the colder months, it's important to perform the necessary maintenance procedures.

Boiler inspection and cleaning

  • The boiler is the heart of your heating system. Its regular inspection and cleaning is necessary to keep it running efficiently. It is better to entrust this procedure to a professional. In addition to the fact that he will competently clean the boiler and remove dirt and soot accumulated over the year, he will assess the condition of the burners and heat exchangers for their serviceability.

Changing the filters

  • Before the heating season starts, replace the filters. They can become dirty over the months of operation, leading to reduced system efficiency or equipment failure. Check their condition regularly during the winter months.

Check chimneys and vents

  • Chimneys and vents should be clean and free of obstructions. Clogging or damage to them contributes to carbon monoxide buildup in the home. If you find cracks, blockages, and other damage, have them cleaned and repaired.

The experts at Hot Cold Air in Chicago are always available to provide professional heating system inspection and maintenance services so you can face winter with confidence and comfort.

Winter Maintenance Tips

In winter, it is especially important to keep your heating system in perfect condition. Following a few important guidelines will help you spend the winter in warmth and comfort.

Checking the fuel level

  • Regardless of what fuel (fuel oil, gas, etc.) your heating system runs on, you should regularly check the fuel level. If the fuel level is low, the system can shut down unexpectedly at the worst possible time. To avoid interruptions in heating operation, especially during severe frosts, plan fueling in advance.

Adjusting the thermostat

  • Set your thermostat to a comfortable temperature when you're home, and lower it a few degrees when you're away or sleeping. Installing a programmable or smart thermostat that automatically adjusts the temperature will keep your energy savings in mind and save you money.

Prevent frozen pipes

  • Frozen pipes can cause serious damage to your heating and water system. To avoid this, make sure all unheated areas of your home (basements, attics, etc.) are well insulated. Leave faucets slightly open so water flows slowly and doesn't freeze. On especially cold days, open kitchen and bathroom doors to allow warm air to circulate around pipes.

These simple measures will help you keep your heating system in good working order and ensure it runs smoothly throughout the winter.
