"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

Heating and Air Conditioning questions, answered by experts

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

It's recommended to change HVAC air filters every one to three months. The frequency depends on factors such as filter type, indoor air quality, and whether there are pets or people with allergies in the household. Regular filter changes maintain proper airflow, improve indoor air quality, and ensure efficient HVAC system operation.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

If an air conditioner is younger than 10 years, it’s worth trying to repair it in most cases. Some basic maintenance or a cleaning might bring it back to working condition. However, many HVAC pros swear by the “5,000 rule.” If the estimated cost of your repair multiplied by the unit’s age is more than $5,000, it’s time to replace it.
