This is a very POSITIVE review. The team of GSHA services are VERY PROFESSIONAL, FRIENDLY, WITH GREAT CUSTOMER SERVICE AND AFFORDABLE PRICE. Everything was well explained by Peter. Questions and concerns are answered day or night and even on the weekend. Installed the Carrier furnace & HVAC and then we decided to add the humidifier after few days in which they did professionally. Thank you for the wonderful Job and keep it up! We highly recommend your company.

My entire experience was positive. Peter, the salesman, explained everything and did not try to upsell or talk down to me as a woman. The installation of my new furnace was scheduled quickly; the technicians did a wonderful job of installing a quality project. I will be recommending this company to my friends.
