HVAC reviews in Arvada, Colorado

Great service, had a full install heat pump and A/C unit. Very easy and easily understood everything they were saying they were doing. In and out in a day. Super helpful and great people

I've read about the value of quality installation of any HVAC system. Lakeside surpassed my expectations with the outstanding installation in my home. They quoted 1 1/2 days to install when others are in and out in often less than a full day. Lakesides attention to every detail was impressive. Jimmy Frey has been doing my spring ands fall tune-ups for a few years now. He's been an exemplary service tech. Highly recommend Jimmy for quality, honest service.

If there were more than five Stars, I would rate Lakeside ten Stars. They were responsive from the first call I made about trouble with my HVAC system, scheduling an appointment right away. Another company said they could schedule an appointment in several weeks, and that was just to determine if there was a problem. So, I chose Lakeside.

Everyone from the employee who helped diagnose the issue (Joe), which was basically a 19 year old system wearing out, and what can be done, to the sales rep (Tony) who also explained about the new system I chose (Daikin with a heat pump), and finally to the installers (Chael and Derick) who were fantastic as well. They all showed up as scheduled and explained my options without pressure. The installers kept me informed about the process of installation, were very patient (especially with my dogs barking), demonstrated how to use the new thermostat, and cleaned up ‘everything’ after a job well done.

Everyone I dealt with at Lakeside was knowledgeable, up to date on HVAC systems and current rebates, patient, and did not pressure me but instead were supportive once I decided what system to use.

While, I recognize HVAC systems are expensive, I believe I received a fair price with various rebates Lakeside offered. It will be the first company I call if I ever need another system or issues with the new one, which I hope is not anytime soon! 😄 I recommend Lakeside wholeheartedly.

The technician that performed our AC check, Jimmy Frey was outstanding! He was courteous, thorough, very knowledgeable and professional. Jimmy explained everything he was inspecting and answered all my questions. His honesty and desire to do a great job with no sales pitch for unnecessary products or services was refreshing. I highly recommend Jimmy and Lakeside Heating & Air Conditioning!

Very friendly, professional and experienced. I have had my air conditioning, and furnace serviced and replaced by Lakeside Heating and I am very happy with everything about it.

Jimmy was very professional. He diagnosed and fixed the issue with my A/C. Issue was the result of a previous HVAC company who supposedly cleaned and tuned up my furnace in Feb. 2025.

Previous company did not clean my furnace, instead they loosened wires to my A/C. This is the reason my A/C wouldn't turn on. Jimmy completed the tune-up on my A/C. He stated my A/C was in pretty good condition. He did not try to upsell me anything. I highly recommend Lakeside Heating & Air Conditioning.

Going forward,

Joe and Lakeside Heating & Air are the only people we call for tune ups or when we need help with our heating/air conditioning. They are friendly, knowledgeable, timely and never try to upsell. Several years ago they earned our business via helping us out of a mess another company created. They were honest and thorough. Now, Joe Z has serviced our system several times as well as some of his colleagues. They always answer our questions, are polite and friendly, and do a great job. Many of our extended family and friends are also loyal customers because of the same treatment.

As a maintenance manager, I rely on vendors who are prompt, professional and trustworthy- and this company checks every box. They respond quickly to service calls, communicate clearly, and consistently provide quality work at fair prices. I appreciate knowing the job will be done right and highly recommend them for all your heating and air conditioning needs.

I was referred to Lakeside by a neighbor who stated they were a family owned business who delivered quality products at a reasonable price. I bought an old home that needed a complete HVAC system.
I had a tremendous experience with these guys. Tony came out and evaluated my needs and provided me with several options. Tony actually recommended the least expensive option, which I went with.
The technicians who installed the system were great. They were clean, polite and a pleasure to have in my home. From what I can see the ultimate work they did was flawless.
If you have HVAC issues, give these guys a call.

The installers were very knowledgeable and friendly. They showed up on time and finished on time. They were also very nice to my dogs and managed to keep them calm.

Had a great experience with the installation team (Mick & Nick). Very organized, efficient, friendly and knowledgeable. This my 2nd furnace and 1st heat pump in 15 years. Many more of family and friends have experienced the same. Hats off to you and the team.

Tony was very through and detailed in sending us multiple quotes for various options. The installers, Mic and Nick, explained what they were doing at the different stages of installation. They covered the work floor area and or booties were worn at all times while in our home. Everyone including Holly, in the office, are very professional and personable.

I got a new AC unit put in, our house is very old and we've never had central air before. They came in and walked us through every step, where the unit would be as well as the wiring and process of moving the heater. Tony B and Chael G did the install, and let me say they are amazing assets to the team. Everything went smoothly. They did such a great job and they even cleaned up behind themselves. I would 100% recommend Lakeside Heating A/C to anyone who needs work done on their heating or cooling units. Fantastic job and Fantastic people.

I can't say enough great things about Lakeside Heating A/C Inc.
We decided to replace our 24 year old furnace and A/C, and boy are we glad we chose Lakeside!
From beginning to end the process was smooth, professional, very friendly and comfortable.
They do what they say they’re going to do, when they say they’re going to do it, and go above and beyond to make sure it’s done right.
Holly was great in communicating times and how the whole process would be done.
Tony did our estimate and was very thorough in explaining what to expect from different systems.
Chael and Derek were AWESOME installers, noticing some existing problems, then taking the time and their expertise to make everything perfect. They really went above and beyond what had to be done.
If you're hesitating on what company to go with for any kind of HVAC service, I would definitely go with these guys. I did, and definitely will in the future.

We recently had the pleasure of working with Lakeside Heating and Air Conditioning, and I can confidently say it was one of the best decisions we've made for our home. Tony, the owner, came out personally to conduct a thorough assessment and provided multiple quote options tailored to our needs. I did my homework and compared his offerings with other well-known brands, and Tony stood out—not just for value, but for responsiveness and professionalism. He answered every question I texted with clarity and patience, earning my trust and ultimately, my business.

The installation team, Kel and Derrick, arrived right on time and impressed us immediately with their expertise and efficiency. Their communication was excellent throughout the process, and they made us feel completely at ease. The dual fuel heat pump system they installed is quiet, energy-efficient, and already seems to be improving our indoor air quality.

From consultation to completion, the experience was seamless. I genuinely don’t believe the install could have been done any better. Lakeside delivered top-tier service, and I wouldn’t hesitate to recommend them to anyone looking for HVAC solutions done right.

Lakeside Heating & AC was the best house-related team I've ever worked with. The quote process with Tony was straightforward, and he took time to answer all my questions. We had several AC companies quote our job, and Lakeside seemed to be the only one who considered our specific house needs. We only have 820 sq feet and a small crawl space, and Tony was honest about what was possible and wasn't trying to shove a one-size-fits-all on me. Holly in the office answered all of my financing questions and was great about confirming appointments and next steps. Calvin's install team was efficient, highly knowledgeable, and professional (and quiet, wow!). Calvin spent a lot of time showing me the system after installation and answering all my questions.

Their prices weren't the cheapest out there, but it was also not outrageously expensive like some other quotes I received. Their work was honest and of quality, AND their 0% financing option was exactly what I was looking for. Highly recommend.

Lakeside has been our go-to HVAC company for many projects over the years, as well as help keep our HVAC systems running great with their maintenance plan. Needed to find a solution to heat my garage, and no surprise that Lakeside came through again with a competitive price compared to others, while getting better quality and products for the price. The installers were very prompt, professional, and the workmanship was top notch. Very happy with our decision to go with Lakeside on this project!

This is a top notch company! Easy to work with. Tony, the owner came by to give me a quote. I had tons of questions which he took the time to answer. The quote was delivered the next morning via email and was the most thorough of the others I received. No questions on what was being covered. Lots of savings with discounts and rebates (which they handled) When it came time to install, Mick and Nick did a very professional job. Also answered any questions. They were very pleasant as well. The contracted electricians were top notch.
Respectable close knit company that makes you feel you are getting the best and that you can call on them for any future care of the equipment they installed. Great experience!!

I have used Lakeside HVAC twice for a completely new HVAC system replacements and have not been disappointed. They're meticulous, efficient and very knowledgeable. They're a model family owned business.

The expertise and overall professionalism of everyone I worked with was a great experience. I'm very happy with my Lennox furnace they installed. I feel confident that if there is an issue they will be there to support me.

They did it again—delivered excellent service. Previously, we had them install an HVAC system at one of our homes, and one of our biggest regrets about selling that place was losing the Lakeside system they installed. From the first call to the end of the job, they get it right.
