Did you know your home’s heating, ventilation and air conditioning (HVAC) system can affect your sleep? Improving the quality of the air in your home can reduce nightly tossing and turning. Here are four ways your HVAC system can affect your sleep.

1. They keep temperatures stable

Research shows that people sleep better in cooler conditions. Bedroom temperatures should be between 15 and 20 degrees Celsius at night. Anything above or below this range can disrupt your sleep. Leaking ductwork, a faulty thermostat or a poorly maintained HVAC system can lead to temperature fluctuations. Installing a smart thermostat, having your HVAC system maintained and keeping your ducts clean will all help to maintain a constant and comfortable temperature throughout your home.

2. They regulate humidity levels

Humidity levels that are too high or too low can adversely affect your sleep. If levels are too high, you may feel sweaty and sticky, and your room will attract mildew and mould. If humidity levels are too low, you could end up with a sore throat, a dry or bleeding nose and/or itchy skin. If you’re battling uncomfortable humidity levels, consider installing a humidifier for your home.

3. They improve air quality

Poor air quality increases allergy and asthma symptoms and prevents you from getting proper rest. Dirty ducts recirculate dirt, dust, pollen and pet dander through your home, which can lead to sneezing, coughing, watery eyes and trouble breathing. To keep the air in your home clean, it’s a good idea to have your HVAC system maintained regularly by a professional, make sure your ducts are clean and habitually change your furnace air filters. You may also want to consider installing an air purification system or electronic air cleaner (EAC) to maximize the quality of the air in your home.

4. They can make noises

An HVAC system that hasn’t been properly maintained can make noises that keep you awake at night. Old fan belts, struggling motors and loose parts can make sounds that will echo throughout your ductwork and into your bedroom. Not only are these sounds annoying, but they’re also a worrying indication that your HVAC system needs an inspection or a repair. Alleviate the anxiety this brings by scheduling a professional technician to look at your system.
