HVAC reviews in Littleton, Colorado

Andrew and Rex came to check out my furnace and they were both so helpful and courteous. They explained what they were doing and even looked into what it would take to install air conditioning in my home. I would recommend them to anyone!

He was very professional and intelligent
He did a thorough job. Explained each step. Answered all questions. Aim high is fortunate to have him as your employee
Thank you. FES

Aim High HVAC operates at a level of professionalism rarely seen nowadays. There simply is no comparable company for the services they offer.
I've had Aim High conduct three projects at my home (furnace replacement years ago, tankless water heater and filtration system earlier this year and most recently replacing my air conditioning system).
Every single time, and every single individual (from the owner, to the service techs, installation crew and office personnel) has been nothing but courteous and positive.
There is an expertise across-the-board with everyone involved with Aim High, and as a consumer, you benefit from that expertise with guidance and insight to make an informed decision. Truly no better, and probably no equal.

Bo was very thorough and professional, he also did a great job explaining what he was doing and why it needed to be done.

Andrew was very patient with me. He thoroughly explained how my newly installed Ecobee thermostat worked. He saved me a lot of time. It was an enjoyable experience. Thank you Andrew.

Bo’s service was excellent. I and however, disappointed to find out when he arrived that I am no longer an elite member and the program is disbanded. I received no notice that this was happening. Therefore, the cost of my maintenance was twice what I was expecting to pay.

Andrew came out to service our 24 yr old furnace. He was thorough, professional and gave us good advice. We will definitely use them again.

Aim High HVAC has been a amazing company! They fixed my AC for a very reasonable price and continue to service my system with super professionalism and a smile. Very responsive to schedule needs, the office staff is as nice as the techs. Every interaction with Aim is so great, I joined the elite program. Cannot recommend Aim High HVAC enough, they truly are a 5 star company!

Fantastic customer service, great products, and the best price!

I feel very fortunate to have Tim and Glenn in my area. I've used AimHigh for their "Elite Membership" service for a number of years now. They come out twice a year to ensure my system is in good order and if I forget to schedule them, they call me (This is great for me)! This year they identified abnormal pressure readings in my AC system and advised me it was likely to fail at some point. It was over a decade old. They also advised me of the signs of failure to look for, what to do if it happened, and gave me good rough-estimate prices for fixes and replacements. Glenn actually came out to confirm the tech's readings (for free) just to be certain. Sure enough, the system died a few weeks later, right before a long vacation.

While I was away, I was able to get them access to the house and they were happy to check it all out for me. I got pictures of the problem and an immediate cost to fix it. As they had stated, fixing it temporarily was cheap-ish, but unlikely to last. We set up an estimate for a full replacement of our HVAC system. When they got back to me (within a few days) I had a detailed least-expensive/middle/and best-system quote laid out for me. I called (still on vacation) and got more details that they were happy to provide. The prices were amazing, in line with their estimate, but certainly way below their competitors. For the price, I went with the highest priced (still not that high) system.

They seemed happy to deal with my crazy schedule and before I returned from vacation and a work tirp the system was replaced! There wasn't a scrap of dirt left over from installation. They provided a year's worth of new filters, gave me a discount because they've done work for me before, provide a much better looking outdoor pad, and replaced/upgraded all of the exterior electrical. They also included and handled the Excel rebates for me. When I got back, Glenn made a special trip to make sure I knew how everything operated and made some final adjustments (no charge).

The system works GREAT! Multiple stages on the fan compressor save a ton of energy and help keep the temperature consistent upstairs and downstairs for the first time ever. My wife is no longer freezing in her basement office while I'm roasting in the upstairs office, it's fantastic! The included remote senses the temperature upstairs and adjusts accordingly and the phone app allows me to make changes from anywhere.

Obviously, I'm super happy overall. I highly recommend Aim High. I will certainly continue to use their services for regular maintenance and I'll be back when my ancient water heater finally goes out.

Damien is professional, very knowledgeable and treats me like family. I was sure I would have to replace my AC unit since it is 22 years old. Damien reviewed his notes on the system he has maintained annually and worked out the issue. I’ve had a relationship with AIM High for around eight years. They have always provided outstanding service.

Today Rex did an awesome job of maintenance on our furnace , humidifier and water heater. In addition, he diagnosed an issue with the furnace which will be covered by warranty. He is very knowledgeable, a great communicator and a pleasure to work with in our home!

AIM High HVAC is a most amazing company. Everyone is professional, knowledgable and they strive to make the experience easy and pleasant with thorough explanations of the work to be done, From the first phone call to Kim requesting an appointment when our air conditioner stoooed working, to Travis coming out the very next day to inspect our HVAC system and let us know what was going on. He is very knowledgable and spent time here letting us know what it would take get things up and running again. We thought the pricing was really fair and transparent. Repair and installation was just a few days later. John did a great job with his team taking care of us. They used covers on their shoes and respected our home and cleaned up really well after to job was complete and answered all of our questions. They have a customer for life!

Aim High is the best! They put in a whole new system for me 2+ years ago. Every time I need anything now a friendly knowledgeable employee shows up and promptly takes care of me. You cannot beat their equipment or their service.

Julian Roman performed my furnace winter service and was very informative of it’s check up and added tips for it to run more efficiently.

A family from my church referred me to Aim High HVAC and I have been a member for a year and am very satisfied with their customer service and the professionalism of their techs.

Thank you Julian!

Rex arrived on time to do our annual furnace maintenance. He introduced himself and asked if we had been having any problems with the furnace and then we talked about what he would be doing to the furnace as part of the maintenance. He got right to work and finished within an hour. We’ve used Aim High for many years and have always happy with their service.

I had an excellent experience today with AIM High HVAC providing routine maintenance for my tankless water heater. Jacob and Travis arrived on time, immediately put on covers for their shoes and got to work. They explained clearly what they would be doing and answered all my questions. I was impressed with their professionalism. They kept the work area clean and finished the job in a timely manner. This is my second experience with AIM High HVAC, and I have been pleased with their work on each occasion.

Today’s install had lots of bumps. Colby handled them professionally! Thanks, Colby! Andy also helped solve some issues for a positive outcome. Great teamwork.

AIM High consistently provides high quality and has never let us down, even with an older house/furnace where maintenance and catching things early is key. Their prices are reasonable and their staff is always professional and courteous Highly recommend them for any HVAC needs!

The team at High were fantastic! The price was incredibly competitive and the service was timely clean and very professional. Aaron and Colby were amazing on site during the installation and Chris was a great coordinator to make sure the service is high-quality. Would use them again!

10/13 Aim High maintenance service with Julian was great.
He's knowledgeable and was able to check out and make repairs to our furnace and humidifier. We've been using Aim High for 3 years now and they are the best company to have for furnace, air conditioner, waterheater

I called AIM High for a furnace diagnostic after hours today. Damien was wonderful! Very professional and prompt. Was out within the hour. So relieved to know everything is functioning as designed with our furnace. No issues. AIM High installed our furnace in 2020. They did a phenomenal job! Gold Star customer service. Thank you, Damien.
