Why did my air conditioner freeze up?
There are a number of possible causes and often multiple causes. “Some” of the most common are low indoor air flow. This can be the result of a dirty filter or indoor coil, poor duct design, inoperable indoor fan motor or too low of a indoor fan speed adjustment. Being low on refrigerant is also a common cause. A refrigerant restriction can often mimic the symptoms of a system that is low on refrigerant. Test instruments and experience are required to distinguish the difference.
My air conditioner tripped its circuit breaker. Can I just reset it?
An air conditioner circuit breaker tripping indicates that there is “likely” a problem that needs attention. You may try to reset it just once to temporarily restore service. We recommend having the system inspected even it the AC works after the breaker being reset.
My air conditioner or heater will not come on. Will replacing the Thermostat fix the issue?
Your thermostat’s job is to turn your hvac system on and of as needed. Because of this it is tempting for a home owner to replace it in hopes that a new thermostat will fix the problem. Unfortunately that most often doesn’t solve the problem and often increase the necessary diagnostic time to fix the actual problem. Do not replace a thermostat unless you have the knowledge to diagnose it as being faulty.
My heat pump’s auxiliary heat is running a lot. Is something wrong with it?
That depends. It is normal for the auxiliary heat to cycle on and off when temperatures drop below freezing. The colder it gets the more auxiliary heat run time is necessary. Your heat pump should be able to “maintain” a comfortable room temperature, without auxiliary heat, in outdoor temperatures 40 degrees F and warmer. The operative word here is “maintain.” Adjusting your thermostat heating set point up a few degrees will typically bring on the auxiliary heat. This is normal.
When should I use Emergency heat.
If your heat pump is working properly, never! Emergency heat is intended for temporary use when there is a problem with the heat pump only.
