Description of Work: Anthony DeMarco co-owner came out and was actually waiting for me when I got home from work.. My air conditioning is a type that is a high efficiency in Summer Park condo park. I think they were an experiment because they didn't put them into the later units. The point is that they are not standard HVAC. my unit was not cooling well.Anthony admitted that he wasn't familiar with this unit and I should probably call an authorized dealer / repair place. Anthony spent about 30 or 45 minutes and told me he wouldn't charge me and I should get my money back from the Angie's list big deal coupon.. He said if I didn't get a refund from Angie's list, he would cut me check..I believe him, but Angie's did indeed refund my credit card without hassle and in a timely manner.. Yes I'm impressed with both A to Z Heating and Cooling and Angie's List.. This was my first time using Angie's List.

Description of Work: Came for $40 Angie's List deal for a service call. Did not have the parts necessary to complete the service at the time. Set up a different date. Although they credited us the $40 toward the service, we were charged full price for the new duct installation. Service man broke a piece of our newly remodeled kitchen tile while hammering the duct in place. Showed me the damage and said he'd have his friend Jason, who works with tile, come and repair /replace the tile at A to Z 's expense. That was on the 19th and it's been 10 days without any word of them fixing the tile. Frustrated. Would like tile fixed asap.

Description of Work: Excellent service. The technicians were very knowledgeable and friendly. I first had my furnace serviced and then had them back to install a humidifier. They took the time to explain how everything worked and even offered to stop by and help change the humidifier filter if i needed it. I would definitely recommend this company.

Description of Work: The furnace was not working. We called and he said he was installing a furnace and would not be able to come to our house until the evening. He came at 8PM and found the problem and fixed it. We had paid $40.00 on Angie's list, but he charged another $49.00 for the repair so I am not sure we saved any money using the coupon. He made some recommendations on settings and we also realized we had not had maintenance since it was installed so he came back a week later and did this for another $89.00. He was very professional and seemed to know his business well. We will call him again if we have problems and need maintenance.

I was struggling with which product line to go with, internet research was not much help. After five estimates with four different brand lines, I decided to go with A to Z Heating and Cooling. The reasons are as follows: A to Z is a small business and provided me a more personal feel. Derek is the one who came out to provide the estimate. Not only is he a owner but he was also the installer, so he could answer all my questions. Derek has ties to my community. A to Z price matched and it was all inclusive. A to Z works with a company that provides financing and Derek got me the lower interest rate. Derek was the only person who pointed out the rooms in my home had a air return deficiency. He didn't try to sell me something I didn't need or want. He provided me all the information I needed to make an informed decision. He arrived when he said he would, did what he said he would do, either answered the phone or returned calls in a timely manner. Submitted all the necessary paperwork to the utility companies to get me my energy rebates. And since time was an issue, Derek worked me into his schedule before the end of the year. He also gave me the assurance that parts and service are available if and when needed. The product works awesome, it's quite and I'm seeing the savings in my billing statements. I highly recommend A to Z Heating and Cooling to all of Northern Colorado.
Description of Work: I had a builders model furnace and ac unit, they were only 8 years old. Both were undersized for my home and required multiple repairs in a two year period. I made the decision to have the units replaced and after an extensive search I selected A to Z Heating and Cooling. I decided to go with the higher end energy efficient furnace with heat pump and ac.

Their service was excellent and I will be sure to refer them out to all my friends.
Description of Work: My furnace stopped working late Saturday night and Derek with A to Z Heating and Cooling was the only person who actually answered his phone from the three companies I had called. He had no problem coming right out to fix my furnace. When he arrived Derek was quick to find that the igniter was bad and thats why my furnace was not working. He installed the new part on my furnace and I was soon warm again. When it came time to pay the bill I was pleased to find out that A to Z does not charge extra for after hours work. Its very rare to find a good contractor that you can trust and I am sure glad I found them.

They did a very good job. I'm really happy with what they did. They explained everything. They gave me options. They said I didn't have to replace it right now, but it will cause a problem later down the road. They couldn't guarantee how long it would last. They were upfront and honest.
Description of Work: I had some remodeling work done in the basement this summer. I was concerned that when they sanded the area it may have gotten into the furnace. They checked to make sure it was alright. They did find a problem with some of the dust that had gotten in there and they cleaned it. They cleaned the furnace and then re-installed it.

Three days ago, I found water all over the floor around the furnace and hot water heater in my basement. My realtor recommended A to Z and so I called them (turns out that she knew of the company when Paul owned it). I spoke with Anthony on the phone and was treated with respect and courtesy (as I woman, I appreciate someone who doesn't talk down to me, especially since it is clear I don't know about HVAC!). He reminded me to turn off the A/C and the water to the water heater. I had already done this but I am glad that he took the time to give me advice that could prevent any more leaks, water, or problems. He scheduled a time with me to come out on Sunday with no additional cost. On Sunday, Derek & Anthony arrived punctually and almost immediately diagnosed the problem - a dirty and cracked condensation pump. Unfortunately, they had just installed their last one and told me that they could come back Monday with the part. Monday they came back and quickly installed the pump. In addition to the quick diagnosis on Sunday, they also looked over the whole furnace and A/C and let me know some things to look out for (i.e. different air filters and where there was some rust on my heating unit). It was such a reaffirming experience to work with these guys who were very punctual and professional, and to see that there are companies out there doing good work, at reasonable prices, and with great customer service. Will definitely be calling them this fall to clean my furnace! :)
Description of Work: Derek & Anthony replaced a broken condensation pump in my 1960's house with speed and professionalism and what I perceive at a VERY reasonable price (and with a couple laughs thrown in!).

Our condo's air-conditioning unit was struggling to keep up with the extreme heat that Colorado had been experiencing; it just was not able to keep our unit cool, constantly running. Not knowing any particular company in the heating and cooling industry, my husband and I saw the company truck parked in our complex and we stopped to talk with the men working. Derek and Anthony (owners) were extremely friendly, willing to talk with us regarding our issue, and scheduled an appointment right htere in the parking lot for, that week. They actually had an opening to arrive early the day of our appointment, called us first to ask if it would work out to come to our property early, and they did just that. Derek and Anthony serviced our air-conditioning unit outside and inside, changed our filter, showed us the results, explained the results, and let us decide which options we would like to choose. I was very appreciative of the time they took explaining what they found (because I know nothing about a/c units) and not only explaining they did not just start expensive repairs. They discussed possiblities with us first, providing price estimates for each option/issue and resolution. We will not only be calling this duo back to work in our home, but we will definitely recommend them to others.
