    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.

    Handy Wired responded to my HomeStar add. Tawanda came and was very helpful. He treated my home with respect. Tawanda (Handy Wired) proved absolutely capable of any job required...this one....climbing 26 ft up onto my roof to seal my skylight that was showing signs of a leak. His work was all that I expected and a few days later he called back to ensure that I was satisfied with the job that was done. That, I appreciated. I will not hesitate to call Handy Wired with any future projects. I would definitely recommend Handy Wired. Thanks Tawanda....great work.

    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.

    Structural work for construction-
    My wife and I are extremely pleased with the work requested and completed by Kitchen And Bath Guys. After submitting our request for quotes on our planned project, of the contractors that responded, Kitchen And Bath Guys had the highest satisfaction rate documented. We reached out to Kitchen And Bath Guys and were immediately contacted by the Operations Manager Vince Spitale. After briefly discussing our project ,Vince came to our home to inspect and get a first hand look at the area that we were considering altering. Within a few days Vince supplied us with a very detailed quote that documented all aspects of the project including a very detailed cost analysis. This detailed direct communication and solid previous customer satisfaction results made our decision very easy to award the contract to the Kitchen and Bath Guys company. Our project was completed in a very timely manner by very polite and experienced workers with no additional cost impact as per the original quote.
