★★★★★
My AC went out during a heat wave and another company's tech tried to sell me a new $9,500 system — pressured me down to $8,500 by the next call. I called C2H. They came out promptly, diagnosed and fixed the problem, and told me a full replacement would've been $7,500 anyway. Been using them for years. They keep proving why I trust them.
★★★★★
Great experience with C2H. Their service/sales team was easy to work with. Paul and David did a detailed job installing my new Trane system. The area was spotless when finished, and they were patient with my questions and concerns throughout the install.
★★★★★
Had two new Trane units installed by C2H. They offered a very competitive price, communicated well, and the install went great. Units are super quiet and I have much better airflow than I did before. Professional quality workmanship — great process from beginning to end.
★★★★★
My neighbor Andrew referred C2H to me. Freddie and Ante were great to work with — answered all of my questions. The installation was great too. Technicians were polite and neat, and the whole system was replaced in less than 3 hours.
