This company is disorganized, unprofessional and the front office needs to figure it out. Not sure if Marc and the sales teams are over promising and Dalco under delivering, but we won't be taken advantage and just go with a estimate that was almost identical. I'd say steer clear for a while and hopefully they figure out how to schedule clients and run a smooth business.

When I went to pay, they said "no charge." I think my jaw hit the floor, but I recovered enough to tip the technicians who showed up on time, repaired the furnace, and were pure kindness.

But I had a great experience today with Cool Heat Mechanical Systems in Denver. My house has two furnaces, both of which needed a check-up and filter change. A friend recommended Cool Heat and I was so glad they had. Paul, the owner, was completely professional, very knowledgeable, and ***gave us one the fairest price*** I've ever gotten from an HVAC firm. The cost for checking both furnaces thoroughly, replacing the filters, running carbon monoxide tests, and spending several minutes talking to us about our furnaces was only $134 which included travel time. We now have smoothly running furnaces, more knowledge than we ever would have had about the age and condition of our HVAC equipment, and the peace of mind to know everything is working well. I would recommend this company to anybody. I'm sure you'll have as positive an experience as I did.

One of my neighbors recommended Cool Heat, so I gave them a call on Friday afternoon around 3:30PM, thinking I'd get a call back next week. He was wrapping up another service call in the area, so came right over in about 30 minutes. He was GREAT! Our HVAC was frozen up with gunk and he cleaned it all up. He did confirm our suspicions about our ducting system - woefully under trunked (old 4" ducts) with lots of breaks. He gave us a reasonable price for upgrading, but recommended that we don't need to do it now. So, we'll now be able to save the money for that project (that we suspected we should have done 4 years ago when we installed our new units). Thankfully, he confirmed that our actual equipment was great and that there is no need to replace those. (My fear was always that someone would come in and recommend a whole new system). Best $125 ever spent - an hour on site to fix us up! We will definitely be hiring Cool Heat to come back to upgrade our ducting later this year! As a bonus, he also services Rinnai water heaters - because we live in Englewood (hard water), we need to get it serviced. I've gotten outrageous quotes for that in the past - his quote is substantially lower than everyone else, so I'll have him to that, too.
