And he also did the usual bi-yearly maintenance oil filter change and furnace cleaning. Thank you!!"

"Horrible service. Although the product defects do not reflect the company, the follow up and customer service were HORRIBLE! The owner, Donald, accused me of "squeaking" because I questioned things. Also, I was accused of having them come out to my house for NO Reason! I spent about $12,000.00 for mini splits and a hybrid hot water heater in the fall of 2022. Sensors have repeatedly been defective on the mini splits. Once again, not the owner's fault, HOWEVER, POOR follow up. Then the annual cleaning was due and I was quoted a price. Upon completion, I was charged $60.00 MORE for the can of cleaner! That should have been part of the original quote, as my husband had been diagnosed with a terminal illness since all this and we are on a fixed budget! NEVER HIRE THIS COMPANY!!!! As of this review, I have been told that I will be refunded the $60.00 for the can of cleaner........holding my breath!"

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

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.

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.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.
