Q: 01. How can I make my home feel less humid after a summer rainstorm?

Does your home feel too humid after a summer rainstorm? Here is a simple solution: run your air conditioning system a little longer than normal at a lower temperature than normal. Your air conditioning system is dehumidifying your home, while it is running. The system will draw all of the humidity out of your home and that cool feeling will return!

Zoning makes your home more comfortable and helps you save money on energy. Your home is divided into independent zones, as multiple thermostats are used. The climate is then independently controlled depending on your desired level of comfort in each zone. Most common examples of zoning are: separating the upstairs climate from the downstairs; establishing a special zones for sleeping and living areas.

By zoning, you have more control over different areas of your home, without having to regularly adjust the thermostat in order to reach desired level of comfort. Rooms inside your home, which are traditionally warmer than others, are easily cooled without placing extra strain on your HVAC system.

Regular maintenance is absolutely vital to the performance and lifespan of your heating/cooling system.

Benefits of regular maintenance are:

  • System will perform efficiently and you will be able to cut down on high energy costs
  • Prolong the life-span of the equipment; avoid unexpected and costly repairs
  • Maintain manufacturer’s warranty
  • Ensure system is running without risk to your health or/and safety
