A website devoted to product reviews has put out an article with tips on how to keep a house cool during the summer. The article is based on the assumption that the house has an hvac (heating, ventilation and air conditioning) system in place. The article offers five tips. Examples include installing a “smart” thermostat, changing the air filter twice a year, and making sure the air flows freely. The article has several color photos illustrating the tips.

Key Takeaways:

• A good way to make an HVAC system more efficient is to invest in a smart thermostat.
• Change your HVAC filter annually, in the spring and fall, to start fresh, save money and boost safety.
• Because HVAC valves, or dampers, are usually not immediately visible, it’s good to look for knobs, or handles, on the exterior portion, in order to manipulate them open.

“When the summer really heats up, even the most robust central air systems can fail without proper care. Maintenance and careful upgrades reduce the chances your air conditioner won’t quit in your hour of need.”
