Thanks everyone for your replies.
 

Thank you for all the responses. I'm going to try to do it myself with the spray cleaner. I watched a few videos so hopefully, if I can get at it, spraying it is a simple job. I'll let you know. :pray:

Thanks for asking that question , it prompted me to google how to clean your air conditioning cooling coil , even I can do it , what outfit was going to charge you 300.00

Ridiculous charge. You can buy coil cleaner spray at Lowes. Spray it through the vents on the outside unit. Also do not use a garden hose to clean the outside coils as you can bend the fins and degrade performance.

Generally-speaking I'm not in favor of publicly bashing a company; however, $300 to clean evaporator coils is outrageous and totally scammy, so in your situation I agree w/ the above poster--as a public service to other area residents you should provide the name of this company so we can avoid them.

If you would like an honest opinion, call Malynn Percy of Jim Percy's Air Conditioning and Heating. They are very honest and will not steer you wrong. It always pays to get a second opinion. They can probably give you a price on the phone. 352-286-6064

Cleaning the coils is easy- i take a small shopvac and soft brush attachment to clean ours no cost

Inquiring seniors are demanding to know what is the name of this offending A/C company. We will storm their shop carrying pitchforks and sickles!
