I've used Lens Applinaces twice. The first time when I purchased a new heating/cooling unit. Then again 2 years later when the AC broke (compressor). They charge $75 for a house call to see what is wrong and then that gets applied to the cost of your repair(s). My unit needed a part that they were not able to get their hands on but instead of sharing this information with me, the owner, kept telling me that the part was coming. Weeks were passing and we were in the middle of a heat wave with my apartment for sale...and no part. I considered going elsewhere but they already had my $75 and kept telling me that the part was coming. After 7 weeks of waiting, the part finally came. The man who does the installations and repairs is a great, helpful, young man. The owner of the shop is old and grumpy and lied to me on several occasions regarding the ETA on my part...which needless to say, I did not appreciate. If he had been honest or up front with me, I could have planned better or made other arrangements. I did not appreciate being left in the dark.
