Don’t let your air conditioner lose its cool or your heat pump get fired up.
First, make sure you know the type of unit you have – the serial number will have the letters ERV (Energy Recovery Ventilator) or HRV (Heat Recovery Ventilator).
Vacuum every three months to remove dust that would inhibit energy transfer. Don’t use water. The core should only be serviced when it’s dry and outdoor temperatures are between 60° F/16° C and 75° F/24° C.
Wash once a year and handle with care. 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.
Regularly check the screen on the exterior intake hood and clean as necessary.
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.
You can always rely on your Carrier® dealer for solutions to any problems you may have with your system, but here are a few tips to try before turning to the experts.
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.
If it isn’t, your system won’t know to provide cooling.
Make sure your outdoor condensing unit is running. If it is not running, make sure the breakers in your home’s breaker box or electrical panel are in the ON position.
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. Make sure it’s in the ON position.
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. If you don’t change it, the filter will eventually block the proper airflow and cause your outdoor air conditioner unit to shut down.
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 all supply registers to make sure they are open and blowing air.
If you still don’t feel the flow of cool air or your system is under-delivering, it’s time to contact your local Carrier expert for service.
Check to make sure your control or thermostat is set in the HEAT position. (You’d be surprised; often that’s the problem.) Make sure the temperature is set warmer than the current indoor temperature. If it isn’t, your system won’t know to provide heating.
Ensure your furnace’s power is on. Try turning the fan to ON using the fan switch on the control or thermostat to test for power to the furnace.
Check the circuit breakers in your home’s circuit breaker box (electrical panel) to make sure they’re in the ON position.
Check the furnace power switch to be sure it’s in the ON position (it looks like a light switch on a gray box located at the furnace).
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 or less, depending on the type. If you don’t change it, the filter will block the proper airflow and strain your furnace.
If you still don’t feel that wonderful rush of warmth throughout your home, it’s time to contact your local Carrier expert for service.
You hear your indoor-unit fan coming on, but the air from the registers isn’t warm or the fan is turning on and off more frequently than usual. NOTE: If your system control has a “Constant ON” feature, you will not always feel warmth, even though air may be blowing.
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. Contact your Carrier expert for assistance if the breakers trip or the fuses blow a second time.
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. When outdoor ambient temperature is below 23° F (–5° C), some degree of defrost mode is possible. 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. Provide your model and serial number. With this information, the dealer will be able to correct any problems.

How to find your model number.
If you need service, or you need to troubleshoot an issue regarding your HVAC system, it always helps to know the model number. Rather than have you commit them all to memory, we made our model numbers easy to find.
Start by looking in your owner’s manual or any other paperwork that came with your product. If you don’t happen to have them handy, you’ll also find the model number printed right on the unit.
Look on the back of your unit, and you’ll find the model number listed on a silver series rating-plate located above the service valve connections. If your heat pump is geothermal, the model information should be easily found on the front of the unit.
Remove the front door and look inside the unit. You should see the model number printed on rating-plate or decal.
You should be able to see the model number on a rating-plate or decal right on the front of a ventilator or an evaporator coil and on the side if you have a fan coil.
You should be able to find the model number on a decal inside the front access panel.
If you own any other Carrier® product, take a look on the front or sides for the model number – we try to make them easy to find. Still unable to find that model number? Just call your local Carrier Expert. He or she will be happy to help you.
