We recently had to replace our furnace and AC units in our first home. Tier 1 has very friendly and knowledgeable staff members. Everyone that we dealt with made us feel comfortable and gladly took the time to fully explain every aspect of the job. They were timely, efficient, and considerate of our home! I would highly recommend this company for your heating and cooling needs. We are beyond pleased with their services! We had a major leak in our AC unit and had to call on Tier 1 several times during the hot month of August. Each time they came out to give us relief until our new unit was able to be installed. We look forward to continuing our business relationship with this company! Thank you!
