As the warm weather comes on, you might be looking at your old (say 4-5 years) air conditioner and longing to buy a new one. Maybe it should be cleaned and unclogged instead. A few facts:
Average life span of an AC - 10 years
Possible life span of a well kept AC - 20 years
Recommendation for light cleaning - each year
Recommendation for deep cleaning - 4-5 years
Rather than throw it out, get it cleaned by one of the few stores which still do it: Frenchman Radio and Television Service , which has been in business for nearly 50 years.
Frenchman sells and repairs air conditioners (along with radios and televisions), and they will visit your home for a Spring Cleaning for $65 (bottom mount) or $75 (top mount) which is all you need to keep your machine in fine shape in the early years.
They offer a Steam Cleaning ($189) for the 4th or 5th birthday, which just sounds great: the machine is picked up, taken away, disassembled and power washed with steam in a steam room. Afterwards, it is reassembled and repainted until it looks and acts as close to new as you can get.
Problems? Frenchman has no website, no computers and (seemingly) one phone, which can make them hard to get in touch with. Also, they get busy during the season (ie. now) so call early. Average turnaround time on a full clean is 2-3 weeks. MGR
