The guy comes out and all he wants to do is find reasons that he can't fix the problem. Suggesting everything from replacing the squirrel cage, if he can find one due to the age of the unit, then it was needing a new motor although it was an identical replacement motor, and finally, replacing the entire unit!!! What a putts!!! I called A&S Heating & Air. Roberto came out, was on time, looked at the mess that I had created, listened to what I needed done and why it was like that. Roberto understood EVERYTHING that I had explained. Stated, no problem, it's what we do and it's easy!!! This guy is polite, professional, he gave me options on what could be done, what he suggested and why! My God, was this guy sent by God! Yes, I think so!!! He is doing the repair right now, I will comment if there are any problems but I don't expect that there will be. And oh yeah, he gave me a rough estimate of what he thought it would cost to do the job!!! If you want your stuff fixed right, from a good polite professional, then go with Roberto from A&S Heating & Air. Trust me, you won't regret it! If you go with someone else, well, that's on you!!!

A little over a week ago my very old furnace stopped working. The fan motor burned out. I searched…read morefor a local repair service to support our local businesses and found Acosta repair was here in La Mirada. My furnace was so old there was doubt we would be able to find a replacement motor for it. Robert spent a week searching for one and when he could have said it was too old and I needed to replace the furnace which is what some places would have said, Robert's persistence paid off and he found one and replaced the motor saving me the expensive cost of a new furnace for a very fair cost of a repair. nice warm house again. Thank you Robert and your repairman. Highly recommend his company for their honesty and integrity.
