Best Gas Furnace Installation in Denver CO

Very good company, responsive to the customer.  Their electricians are very knowledgeable.  Excellent customer service!

Would have said I really liked this company because I used them for service calls for rental properties I manage. They ended up being more expensive than another company for a furnace replacement and I did not use them so now they will not do business with me anymore. Just ungrateful and said they expect me to be loyal and pay a higher price or they don't want to do business.

Wow! The best HVAC service I've ever had in Boulder! Our heater stopped working last evening. We kept a fire in our fireplace going and called this company first thing in the morning. The temp has been in the single digits all night and the lady who answered was kind, compassionate, and quick. She got us the first available appointment at 1pm, and then they called to see if they could come early! Timothy called us when he was on his way. He was clean, efficient, and super knowledgeable. He fixed our problem within an hour and explained the whole process to my husband. We are impressed! We will be dedicated customers for sure as they offer lots of home repair and consulting services.

Thanks for the great help! Dominique was good at fixing what needed fixed and he let me watch. I like to learn and he was great about letting me learn!!

Cooper Heating & Cooling just completed my furnace replacement and adding central air to my home in Parker Co. The first day was removal of the old furnace and installing the new one. Every thing went smoothly and quickly! Cooper had five technicians here! The furnace was installed and working when they left for the day! The next day two  techs returned and installed the ac unit. The installation is clean and neat, with a lot of attention to detail! We could not be happier!

On-site quote and estimate for electrical work performed in February, the price quoted was $2,225. They came out again a few days before the work was to start and requoted the job with a discount, new price $2,100. Three days before the job was scheduled to start they called and said both of their electricians quoted the job wrong and the price was now $3,800. This is completely unethical. The company is basically stating that two of its senior electricians are incapable of working up an accurate onsite quote. I think they were hoping I would just agree because I wanted the work done. I did not agree with their price gouging and unethical business practices. I highly recommend not using this company under any circumstances.

Can't give me even a general price over the phone, but it's 42.95 to have someone come out and tell me a price.  Are you serious?  Very poor customer service.

It made me sick to my stomach when I realized that this company is a complete scam. I have never written a negative review before, but I cannot in good conscience let them get away with what they did. They took advantage of my wife when our furnace stopped working on a cold day in January 2023. They convinced her that our furnace needed urgent replacing, and used gross sales tactics to pressure her into making a quick decision. In the end, they ended up replacing our entire furnace for over $13,000. They quoted us for an entire HVAC system for $28,000, which is beyond ridiculous. Luckily, we refused that offer, but we fell for the furnace quote. It was our fault for not doing our research, but they told us they were almost out of stock and we had to act immediately to not be at risk of losing heat again in the middle of the night. A comfort adviser came over and convinced us that we were getting a great deal. They subtracted the cost of the very expensive repairs, so in the end the furnace cost $12,500. After my wife signed the paperwork and they installed the furnace, I got a sinking feeling. The furnace was not as great as they had promised. Then, I went online and did a little bit of research. First, I found out that the type and brand of furnace we got should have been between $1,500 to $4,500 with an install cost of $500-$2,500. In other words, they charged us double what we should have paid. Second, I started researching this business on Yelp and BBB. I realized that I was not the only victim of their scams. Run away, run far away from this unethical company.

Fantastic job by Ray and Brian, who worked as a team.  Our 50 gal hot water started gushing water first thing in the morning, causing panic in our house.  As I worked to shut off the water, my wife called AAA.  They were very helpful in telling her the steps we needed to take to get the water shut off.  They were able to get Brian to our house by 10am.  He found that the water heater was shot and gave us options to replace it.  We decided to go with a tankless heater.  Ray joined Brian at our house about 11am and by 3pm they had removed the old tank and installed and tested the tankless heater.  They did an incredible job, they were fast and courteous.  They cleaned up the area after they were done.  We were back in business that quickly.

I had a backed-up sewer drain and I thought I would give Plumbline a try. So I scheduled an appointment and Noah from Plumbline called and let me know he was on his way. Noah arrived and listened closely to my comments and then made his own inspection. Noah decided on an entry point for his drain cable machine and then methodically ran the cable in and out until the blockage was cleared. Noah tested his work by running extra water down the drain and there was no longer any backup. Thank you Noah !!!
I recommend this company.
