Our old furnace died on the coldest Friday night of the year in Albuquerque; I called many places and everyone else could only promise Monday service. When I called Daniel's the owner himself answered the phone and was at the house within the hour and this was at night. Our furnace was so old he doubted that he could find a replacement part and since there were other issues with our 23 year old furnace I decided it was just time to replace it. Fearing it would take a couple of days the owner told me he could have it installed by the next day! They had other jobs but promised they would work late if necessary to get the job done. The crew of 3 showed up about 6PM and got right to work; they were done withing 2 hours! I was very impressed with their professionalism and quality of work...I will use them exclusively for any of my future HVAC needs.
