I was referred to Stark by another Yelp Elite (thanks Ericka C.!). From start to finish, Stark was awesome! We had a home warranty claim that wasn't taking care of the cost of the needed services, so after having 3 other estimates, we called Stark. they promptly dispatched a technician (Justin), who came out to take a look at our system and troubleshoot what was needed. He arrived, and put on some little booties, so as not to get our carpet/flooring dirty. None of the other companies did this :). He was polite and knowledgeable. We knew we were in good hands.Sadly, after having bought our home 11 months earlier, we needed a new air handler in the attic, all new duct work, 2 new returns, and the large A/C heat pump condenser unit outside the house. What-a-mess. BUT, their assessment was consistent with what the other companies advised (with the exception of the crummy home warranty company who wanted to replace only the air handler, at a cost of $1700 to us, and $500 to them).Next, the sales associate came on out to the house. He also put on the little booties, and was very respectful and courteous. He had our system planned out for us, measured the house in full (with a laser), and helped us select our whole home heating/air conditioning system. The system he proposed was for less square footage the other companies proposed. The other companies did not accurately measure the house, and were going off estimated square footage. So glad we didn't pay for something we didn't need! The sales associate was super kind knowing the cost of the system was pretty unexpected and pricey. He was knowledgeable and was able to help us find price breaks. We had this done in winter, so we were able to take advantage of some very discounted pricing, since this time of year is very slow for these companies. They also offer financing, if needed.The installation was scheduled for that very same week, and the installation crew arrived early in the day, and stayed until late in the evening. They were fabulous, and involved us in some of the decisions (including where the returns would be placed), and showed my husband the entire system in the attic and in our house. They even checked our existing returns and vents, and sealed better, to ensure the system worked as efficiently as intended. I couldn't thank them enough. After having been without air conditioning starting in August, all the way through December, we were thankful to have a top notch system in our house.After the install, Stark schedules an inspection with the city and also the Stark team. City inspection went flawlessly. Stark sent Mason out, who does the final inspection for them. There was one part of the wall that had gotten left open, and a small animal got inside. Mason helped get the animal out, and seal the old (no longer used) return. Problem solved.Stark didn't have the most competitive prices, but they did have the most top notch team, customer service, and installation crew. They also offered financing. With the superb referral from a fellow Yelper, we chose Stark, and we couldn't be happier that we did. What a great experience! Highly recommend this fabulous company.
