If replacement makes more sense than repair, we'll be honest about it and help you choose an efficient, reliable new system.

While Colorado is known for its winters, summer temperatures regularly climb into the 90s, making reliable cooling essential. As your local air conditioning contractor, we help you select the right cooling system for your home's size and your family's needs.

We also offer financing options to make new system installation more affordable for Fort Collins families.

Colorado's hottest days can push your air conditioner to its limits, sometimes resulting in breakdowns when you need cooling most. Our air conditioning repair service prioritizes emergency calls during heat waves, bringing the tools and parts needed to get your system running quickly. We won't leave you sweating while waiting for ordered parts.

Prevention is the best form of air conditioning repair service, which is why we recommend annual maintenance before summer arrives. Our thorough tune-ups clean vital components, check refrigerant levels, test electrical connections, and identify potential problems. This simple service can improve efficiency, lower your energy bills, and extend your system's lifespan.

Faulty wiring, outdated electrical panels, and flickering lights can signal serious problems requiring professional attention. Our licensed electrician team keeps your home safe with expert repairs and upgrades that meet current code requirements. We take electrical safety seriously, thoroughly testing all work before considering a job complete.

Modern homes demand more power than ever for computers, entertainment systems, and smart home devices. Our comprehensive electrical services address everything from minor repairs to complete system upgrades.

Customer Reviews

My entire experience with Allen Service was beyond expectation. We are buying a new home and had some concerns about HVAC and plumbing. Shannon was so very helpful in answering my questions and Daniel was able to get us in quickly because of deadlines due to home buying. I was amazed! Jeremy was our Tech and I can't sing his praises enough! He explained everything to me in a way that was easily understandable and showed me what he was talking about as he explained. He was also was ready, willing and able to answer all of my questions. I will definitely be using Allen Service for my future needs.
– Michelle A.
I'm not one to post many reviews or voice something publicly. But I will recommend this company 10 out of 10 to everyone. The owner is a man with heart and passion that loves even the little man, and their tech's work shows it. Kevin was my tech and was probably the nicest person I've ever had the pleasure of meeting. These guys are your guys for the job.
– DH Battle
Robert did a check of our air conditioner and furnace. He could not have been more thorough and professional. We would definitely want him to do our next checkup. He is truly an asset to your fine company.
