Cottrell & Co., Inc. Plumbing, Heating and Air is a full service residential and commercial plumbing, heating and air company that has proudly served the Columbia and Lexington areas since 1995. We have enjoyed building a reputation of excellence through quality parts, expert employees and maintaining high standards of workmanship. We pride ourselves in communication with our customers by listening, offering multiple solutions and always giving the price upfront. We also offer 24-hour emergency services.

"Do not use this company for backflow tests! I called Cottrell for a simple backflow device test. I was charged $213 for a backflow test which was over twice the amount I was told to expect by friends and family who had the same test done by other plumbers (one even showed me his invoice for $35.00). It is an absurd price for a very simple test and far overpriced compared to other plumbers in the area."

"Still waiting for a call back after initial visit. They were to move forward but no time schedule yet and A/C not working. As of now, this looks like 4 days of wasted time as I am not sure their customer service exist. The lady this morning said she would mark as urgent and get to a manager. You would think a simple call to a customer explaining backlog or schedule repair date should not take more than 5 minutes. Will give them until later today and then move on..."

Heating and Air Conditioning questions, answered by experts

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around 15 years, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider replacing the AC unit rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.
