I purchased a new furnace from Cota's Comfort and they installed it as well. They were absolutely wonderful! They are well staffed which means there is no wait time for someone to arrive for any problems. They know without a doubt what they are doing. I have had absolutely no problems with my new furnace or with them. This past week I had a lightning storm which hit my house and they were out right away to check on my furnace. I cannot say enough good things about this company!
