On the advice of a close friend, we turned to Assured Comfort when our HVAC was acting up last summer. Assured Comfort was so good, we dropped the outfit we used previously as well as the home maintenance insurance company recommending them. When the Assured Comfort repairman advised that repair on the builder's grade HVAC would eventually approach the cost of a new unit last month, we took the plunge. All has not gone smoothly, but Assured Comfort has fully backed up their warranty by answering our distress calls 24/7 and by dispatching qualified and respectable repairmen within hours. Am I pleased? Definitely yes. One learns more about a company and its philosophy when things do not always go as hoped. From those answering the phone, to repair, to billing, we are impressed with Assured Comfort.
