  • What's the importance of indoor air quality?
    Many Americans spend up to 90% of their time indoors. Today's buildings and homes are constructed to be as airtight, and thus energy efficient, as possible. With the rise in chemicals used in cleaners, construction materials, pest control and many daily living products our indoor air is becoming more polluted than our outdoor air. In addition, common indoor pollutants such as dust mites, pet dander, cigarette smoke, bacteria and molds mean this lack of fresh air can lead to health risks. Trapped air pollutants have been linked to allergies, asthma, toxicity, and even cancer. To make matters worse, those who generally have the greatest prolonged exposure are those who are most susceptible such as children, the elderly, and the chronically ill.

  • Can I troubleshoot before calling Marlin James?
    The answer is "Yes." Here are some simple procedures you can perform before scheduling a technician:
    • Check disconnect switches (indoor and outdoor if you have a split system). Make sure that circuit breakers are ON.
    • Check for sufficient airflow. Make sure air filters are clean and return-air grilles are unobstructed.
    • Check the settings on your thermostat. If you want cooling, make sure the temperature control is set below room temperature and the SYSTEM switch is on the COOL or AUTO position. If you want heat, make sure the temperature control is set above room temperature and the SYSTEM switch is at HEAT or AUTO. The FAN switch should be set at AUTO.
