NASHVILLE, Tenn. - Metro police are investigating cases of air-conditioning unit thefts.
Police believe thieves are reselling them for a profit.
A West Nashville homeowner said someone snatched up the entire central heating and air conditioning unit from outside his home.
Police said some of the incidents are happening during the day.
Chris Choate used chains to bolt it down, but it didn't seem to help.
"It would take a truck or backhoe to pull this thing out of the ground," said Choate who lives in West Nashville.
Police are also investigating four similar thefts that took place within the last three weeks in North Nashville.
Once incident was recorded by a security system.
"He's just cutting. It shows him with a cutter, cutting the lines," said Metro Sgt. Tony Blackburn.
Detectives believe the two thieves who targeted a home on Arthur Avenue weren't interested in the copper found in the units.
"If these thieves were to successfully steal this, which they do, they could actually re-install this at a house and charge the install fee as well and probably make $5,500 or even $6,000," Blackburn said.
The home security system video showed that the crime took place during daylight hours. Cars are showing passing by as the pair remove the unit.
When the air conditioner wouldn't fit inside their white Ford Expedition, they left and returned 40 minutes later -- better equipped to haul it away. They returned with a flat bed trailer.
Choate isn't taking any chances on thieves striking again.
"We're in the process of building a cage to keep it from happening. So we think," he said.
Police hope someone recognizes the two suspects or the vehicle they used. It's an older model white Ford Expedition-- possibly built between 1997 and 2002. The flat bed trailer attached to it had a white rim on the back tire and a black rim on the front tire.
If anyone can help track down the thieves, call Metro police. Police said they began noticing thieves taking entire air conditioning units in the spring.
