Maintaining a comfortable and energy-efficient home in Calgary can be a challenge, especially with the extreme weather conditions the city experiences. Ensuring your HVAC system is running smoothly is crucial, but homeowners often make common mistakes that can lead to inefficiencies or costly repairs. Understanding these mistakes and knowing how to avoid them can help you keep your home comfortable and your energy bills in check.

Ignoring Regular Maintenance

One of the most common mistakes is neglecting regular maintenance. Your HVAC system requires periodic check-ups to function optimally. Skipping these check-ups can lead to a decline in performance and even system breakdowns. To avoid this, schedule professional maintenance at least twice a year—once in the spring and once in the fall. This ensures that both your heating and cooling systems are ready for the upcoming seasons.

DIY Repairs

While it might be tempting to tackle HVAC issues on your own to save money, DIY repairs can often lead to more significant problems if not done correctly. HVAC systems are complex, and improper handling can void warranties or cause further damage. Instead, hire a qualified technician who can accurately diagnose and fix any issues, ensuring your system runs efficiently and safely.

Incorrect Thermostat Use

Another frequent mistake is improper thermostat use. Setting it too high or too low can waste energy and strain your HVAC system. Consider installing a programmable or smart thermostat that can automatically adjust the temperature based on your schedule, optimizing energy use and reducing wear and tear on your system.

Neglecting Air Filters

A clogged air filter can severely impact your HVAC system's efficiency. It restricts airflow, causing the system to work harder and leading to higher energy bills and potential damage. Change your air filters every 1-3 months, depending on usage and whether you have pets or allergies. This small step can significantly improve air quality and extend the life of your system.

Overlooking Insulation

Inadequate insulation is another issue that can undermine your HVAC system's efficiency. Without proper insulation, your home may lose heat in the winter and gain heat in the summer, causing your system to work overtime. Check for drafts around windows and doors and consider adding insulation to your attic and walls if necessary.

Blocking Vents and Registers

Ensure that vents and registers are not blocked by furniture or other objects. Obstructed airflow can cause uneven heating or cooling throughout your home, forcing your system to work harder than necessary. Regularly check that all vents are clear and open for optimal performance.

Choosing the Wrong Size System

Lastly, selecting an incorrectly sized HVAC system for your home can lead to numerous issues. A system that's too small won't effectively heat or cool your space, while one that's too large will cycle on and off frequently, wasting energy. Have a professional assess your home's size and needs to recommend the appropriate system size for maximum efficiency.

Avoiding these common HVAC mistakes can save you time, money, and hassle in the long run. Regular maintenance, professional repairs, proper use of technology, and attention to system components all contribute to a comfortable and efficient home environment.
