"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.

Whatever your home needs, I’m the man to help you see it done. If you own a home you've probably encountered a really thorny puzzle. There are contractors. They’re just the right people for medium to large home projects employing one to many highly skilled workers. For this man’s expertise you’ll pay top dollar. On the other hand there are day workers you can pick up outside of Home Depot. These folks are just perfect for unskilled small home projects. They’re men who’ll work very hard, but who have limited skills and little training. Thankfully they’re inexpensive. Their problem is you can’t really expect more than general yard and home cleanup from them. Additional DBAs - B D Home Improvements, The Small Job Guru.

"Bruce responded quickly to our request for quote, went over details of job, estimated the cost and gave us guidance on prep for the job. He called again to confirm the appointment, and was on time. He was very organized in setting up for the job. He was meticulous but fast in his work - the joins in the siding were perfect. Overall, very professional, easy to work with, and we would recommend Bruce."

Heating and Air Conditioning questions, answered by experts

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

In many cases, replacing the entire AC system is a better investment than replacing a condenser or evaporator coil, as the labor and part prices can add up to a significant portion of the cost for a new system. Consult a licensed HVAC technician for an accurate diagnosis and recommendation.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
