Our furnace has the same age as the house we bought which is 30 years old. Nothing more to say the furnace does need replacement. A new immigrant from a tropical country who have worked most of our life in the desert, winter is totally new for us (in fact risking a season depending on the beat up old furnace before deciding to replace it). I am a cautious consumer and my only principle is value for money, I always say, I am not cheap, but frugal. With no knowledge of furnace products, suppliers, contractors etc., I depended on Google and friends (and their own googling...), until I stumbled upon HomeStars and Kent's 'Do It Right'. With a company name as such, who would not look in to it. Kent visited and inspected our home on the date as agreed and gave us a quote. We also were able to get quotes from other big name furnace contractors offering but same products. What made us decide to go with Kent (apart from his company's name) is that He was able to give us a good alternative product that offers the same purpose for a very reasonable and a very competitive cost. Value for money is what we got. The install went as per schedule, smooth and clean. Our new furnace was installed last September and waited to to do the review only now to see the performance of the furnace first and no complaint to date in fact we are really glad we had the furnace replaced and have 'Do It Right' do it for us. Thanks Kent.
