I've been a loyal customer for 12+ years. I was happy enough their service to recommend them to my husband, who owns a seperate property from me. He purchased a new air conditioner from them. I completed their referral paperwork and nothing. I've even followed up with an emailed and phone call, and I kept getting the same song and dance that the owner needs to sign off on it. My husband got his air conditioner installed in March. Not sure how long it takes to approve a referral, but I've given up and will no longer recommend them.
