"My dad is elderly and needed a new HVAC system. So I decided to find a person who could install a new HVAC system and we found Cody. Cody was very friendly, honest, and communicated very well. At one point he told us we could probably go another 3-5 years with the current system, but since my dad only has so many years left we told he to go ahead and install a whole new system in. He treated us like gold and even spent the time showing my Dad all the new features with the thermostat. I would highly recommend Cody for any repairs or HVAC needs you have."

"Controlling Systems was very easy to work with. They worked with our budget and needs and tried to get us the best price for our unit. When we called with a competitive quote (lower) but wanted to go with them, they were able to add an additional discount. The sales person and installers were both on time and very courteous. They covered the floors to protect them while they worked, and cleaned up after installation. After installation, the installer showed us how to use and maintain the system. We will definitely use them again for maintenance."

"I hired them to install AC in my older home. Excellent communication from beginning to end, brought in their own electrical contractor so I did not have to coordinate this step, the final cost was less than the estimate! Honest and Trustworthy. Integrity and pride in workmanship!"

"These are different times with the virus. Because of my age I have to be careful. And so it's important to say that DMC followed all protocols without prompting, with masking, social distancing, and was even careful to contact no surfaces unnecessarily, and so was very professional and courteous with these not-so-pleasant issues. But to back up a bit, knowledgeable diagnosis of the problem began with the initial phone call. Experience counts, and the diagnosis was confirmed quickly upon arrival. Tests were done in front of me, and the problem explained clearly. I had called in early morning, and was scheduled in, despite three other jobs planned for Les (the tech) ahead of mine. He arrived in the first fifteen minutes of his predicted time-window, and his work, despite challenges described below, was as efficient as his predicted arrival, The job was complicated first by the furnace not being installed in its most conventional and accessible way, and second, even though he would have made the replacement with a universal motor to save cost, the particular furnace required its specific part only. This said, he knew exactly where the nearest distributor was, and retrieved the necessary replacement quickly. Despite the difficulty of the disassemble/installation and having to retrieve and use only the specific replacement, his price point was well within researched averages, This was a great comfort, and another reason to leave this highest possible review for a top-flight service company. Based on such, DMC will be the first company I call for any further a/c or heating concerns. Thanks!"

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

FAQs for window a/c unit service or relocation projects in Firestone, CO

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
