    Repair or maintain airconditioning-
    I had a leak in condenser coil of the AC and they were able to help replace it with a brand new coil. They did not do any upselling for replacing AC or anything. They arrived on time in the morning, cleaned up the area of work, laid down protective sheet on the floor and got to doing the fix. They did very professional work with the coil replacement, filled up the gas and cleaned the full area. I also asked them to clean and service the outside unit which they happily agreed despite adding time to their work. They did a great work overall and now my AC is working optimally. Very cool guys, keeping us cool in this heat. I will surely call them again without hesitation in the future.

    The furnace stopped working and once I asked for service on Homestars, I received a message and a call within the hour. The person on the phone helped me troubleshoot the situation (a loose wire on the board) and we were able to fix the issue without a service tech even having to come over. I really appreciate the care and priority they gave to a customer over anything else.
