To prevent overworking your AC:

• Make sure the filters are clean and replace them regularly.
• Keep the outdoor unit free from debris

Yes, heat pumps are designed to both heat and cool, making them suitable for both winter and summer. They are very efficient during heatwaves, particularly when paired with variable-speed or inverter technology, which allows them to adjust their output based on the cooling demand. Ductless mini split heat pumps are especially effective in cooling specific zones of your home.

If your HVAC system has been properly maintained, it should be able to handle the demands of a heatwave. However, systems that are older or in need of maintenance (e.g., dirty filters, low refrigerant levels, or poor airflow) are more prone to breaking down under extreme conditions. Regular maintenance and inspections can help prevent breakdowns.

It’s generally better to keep the AC on and set the thermostat to a higher temperature when you’re not home, rather than turning it off entirely. This prevents the system from having to work harder to cool the house down once you return. A programmable thermostat can automatically adjust the temperature to save energy while you’re away.

No, setting your thermostat to a very low temperature won’t cool your home faster and will just make your system work harder. It's best to set the thermostat to a comfortable temperature (usually around 78°F) and allow the system to cool at a normal pace. Extreme temperature changes can also lead to unnecessary strain on your AC.

First, check if the thermostat is set correctly and if the circuit breaker has tripped. Then, check the air filter to see if it's clogged or dirty. If the unit is still not working, call a professional HVAC technician immediately. A malfunctioning AC during a heatwave can cause discomfort, so prompt attention is crucial.

Yes, ductless mini splits are ideal for cooling during heatwaves, especially in homes without ductwork. They are very efficient and can provide consistent cooling to individual rooms or zones. Their performance depends on the unit’s size and the cooling load in your home, so ensure it’s properly sized for your needs.

To optimize performance during a heatwave:

• Use a programmable or smart thermostat to keep temperatures consistent and avoid overworking the system.
• Close curtains and blinds to block out the sun and reduce cooling load.
• Seal any air leaks around windows and doors.
• Ensure that the air filters are clean, and the outdoor unit is free of debris.
• Turn on ceiling fans to help circulate cool air more effectively.

During a heatwave, your air conditioner might struggle to keep up with the extreme heat if it is undersized for your home, the filters are dirty, or if the system hasn’t been serviced recently. It’s also possible that the refrigerant levels are low or that the condenser coils are clogged with dirt and debris. To improve performance, make sure your AC is serviced and that the filters are replaced.
