That's why manufactures include a maintenance requirement in their warranties, and failure to complete the cleanings regularly will result in loss of coverage.

I had an excellent experience w 5 Diamond.. my AC has now been serviced and is running efficiently..and I only contacted them last week! That's pretty unheard of in this type of industry. I also appreciated the time Justin spent showing me the functions of the AC Unit and what to keep an eye on.. he even made sure the water overflow sensor was actually working.. oh and he was on time and very pleasant too.. thank u!!
