Each year new codes are passed and some old ones are thrown out so you should have a Bartlett Heating and Air technician come out and inspect your mechanical room. Some are as small as water valves and can be as large as piping requirements for high efficiency furnaces. If you were planning on selling your house, you have to have all the code violations fixed beforehand because they do inspections and it can become a big headache. It is also a safety liability so call Bartlett Heating and Air today to have it checked and make sure you and your family are safe.
