Identify air conditiong model numbers

Window Air Conditioning Systems are typically installed in an open window and usually connect to power with a V or possibly V power cord. As these systems usually have an integrated thermostat, they are incompatible with Insteon Thermostat. Mini-Split or ductless systems place one or several indoor units in your home that connect to an outdoor compressor.

These systems usually operate as a heat pump. Most mini-split systems are usually supplied with a proprietary, integrated thermostat and as such, are incompatible with Insteon Thermostat. If your system offers an adapter to connect 3rd-party 24V thermostats, it may be compatible with Insteon Thermostat for Heat Pumps. Most standard central air conditioning systems consist of an indoor air handler and furnace as well as an outdoor compressor.

Small vent registers are located throughout the home with ducting returning to the central air handler. As these systems can vary greatly, it is best to inspect the wires connected to your existing thermostat. The colors of wires in your home may vary. If you are still uncertain, search for the brand and model number of the large condenser unit outside on the internet. Portable units can be moved from room to room and usually connect to power with a V or possibly V power cord.

What are you looking for?

Direct-vent millivolt heaters are usually older single-room systems that are controlled by a 2-wire or battery-powered thermostat. Some are large and mounted on a wall, others may be integrated into a floor register. Examining the thermostat, you should find only a red and white wire. As these systems do not supply power, they are incompatible with Insteon Thermostat without additional products. Electric baseboard heaters are usually long and shallow metal enclosures located along the baseboard throughout rooms in your home, controlled by a thermostat or wall switch located in the same room.

Some line voltage systems may also be enclosed in a wall vent with a blower fan. Examining the thermostat, you should find thick wires connected with wire nuts. You may also see labels warning V, V, or high voltage. Check to make sure your control or thermostat is set in cooling mode. Make sure the temperature is set cooler than the current indoor temperature.

Make sure your outdoor condensing unit is running. Check the main power switch for your outdoor unit, usually found within a few feet of the unit in a box mounted to the exterior of the house. Ensure that the blower motor in your furnace or fan coil is running. If the system is set for cooling, the blower motor should be running.

If not, check to make sure your indoor unit switch is in the ON position. Check the filter for buildup. If you have one-inch-thick furnace filters, a once-a-month change is recommended. Two-inch-thick filters — and other high-capacity pleated filters — usually only need to be changed every other month, depending on the type.

Check all return air grilles to make sure they are not blocked. Return air grilles are larger and are located on a wall or the ceiling in newer homes. Older homes frequently have return air grilles on the floor. Check to make sure your control or thermostat is set in the HEAT position. Make sure the temperature is set warmer than the current indoor temperature. Try turning the fan to ON using the fan switch on the control or thermostat to test for power to the furnace.

Two-inch-thick filters — and other high-capacity pleated filters — usually only need to be changed every other month or less, depending on the type. Check the main power disconnect switch. Verify that the circuit breakers are ON or that fuses have not blown. If you must reset breakers or replace fuses, do so only once. Check for sufficient airflow. Check air filters for accumulations of large particles.

Check for blocked exhaust air grilles or ductwork. Keep grilles and ductwork open and unobstructed. Check to see if the unit is calling for air exchange or if the unit is in defrost mode. Defrost time could be five to 20 minutes, depending on temperature and settings.

If your ERV still fails to operate properly, contact your Carrier expert — and be sure to have your model and serial numbers handy. With this information, the dealer will be able to correct any problems. If the condensate fails to drain properly, check the grommet and drain tube for obstructions. Make sure that the condensate drain tube has a slight slope and is not kinked.

If your HRV still fails to operate properly, contact your Carrier expert. Vacuum every three months to remove dust that would inhibit energy transfer. Wash once a year and handle with care.

Why choose Daikin?

Soak the core in warm water and mild soap for three hours and then rinse under warm not hot water. Filters in your ventilator are washable and should be cleaned every three months. Use a vacuum cleaner to remove accumulated dust and then hand-wash in warm water. Changing the air filter is the only maintenance required.

Filter life varies from home to home and is based on several factors, but most last from eight to 12 months. Have your Carrier geothermal expert come once or twice a year to make sure your system is operating at peak efficiency. If your geothermal unit is connected to well water instead of a closed loop, we recommend the heat exchanger inside the unit be cleaned periodically to prevent the buildup of minerals that can reduce system performance.
