Air Conditioner had a tune up in May. Contractor said it was working perfectly. In July stopped working completely!! (2nd service fee) HSA sent it to a contractor that doesn't do emergency service. Then proceeded to wait for them to respond hours later regarding the fact that they don't do emergencies. Now, we have to wait another entire day to get anything soe with our unit! User's recommendation: DO NOT USE HSA!!! THEY ARE TERRIBLE!! AND NEVER LET YOU SPEAK WITH A SUPERVISOR.
