For optimum efficiency we recommend cleaning and servicing your HVAC system twice yearly, in the Spring and the Fall.

We recommend checking your air filter once a month. Dirty air filters put stress on your HVAC system that may lead to operational issues. It’s a good practice to replace your air filter every three months, but most find they need to change it more often due to dust, dirt, and pet hair.

It most efficient to find a temperature that is comfortable for your household and maintain that set temperature, offsetting the temperature by only a degree or two.

Less is more!!!! Over time food items may restrict your pipes, causing a headache for you and your plumber.

Average life expectancy of HVAC system is 20-25 years. Average life expectancy of water heater is 12-15 years. Life expectancy can fluctuate drastically based on proper maintenance. Neglected units do not last nearly as long.
