Cannot compliment the Lakeside team enough. Professional, courteous, helpful, on time, did as they promised. One of the very best vendor experiences we have ever had. Thank you very much.

Overall the experience with Lakeside Heating was good. Quote for the job and booking the install was fast & easy. Got a tankless unit that is really nice. The guys that installed were super nice & professional and did the job quickly. Tony made the one and only hiccup right & did so professionally and quickly. Absolutely awesome to deal with. Give them a shot. You won't be disappointed.

We called Lakeside after a very frustrating experience with another company. Our older furnace began stopping intermittently. After the first company was unable/unwilling to investigate the issue, I did a little research and called Lakeside. Their technician came out the same day, listened to my explanation of the problem, went downstairs, immediately found the issue, and had the furnace running again in a matter of minutes. at a price that was a fraction of what we were quoted from the other company. Needless to say, we will be using Lakeside from now on!

I had Lakeside replace my furnace and install a new whole house A/C. The entire process was very professional, open and honest, and efficient. The quoting process was thorough and Tony listened to what i wanted/needed and gave me 4 relative bids - complete with every option, detail and cost. All the other bids I received from other companies were lacking in either detail or weren't aligned with my needs well.

They answered all my questions beforehand 9and there were many. They scheduled the install very quickly and were prompt both days. The installers were early, communicative and very good at their job. They did really professional work, talked with me through a couple of items, and even did a couple small things for me to make the job better. A company like this can have good management and office staff, but without good installers the company will suffer - and these installers were excellent.

Everything was clean and ready to go earlier than planned on both days. The final cost was exactly what was quoted, and it was very competitive for the efficiency I chose. The system works great in the first two weeks, and the warranty is in the industry high end. I cannot recommend a company more highly than Lakeside heating & Cooling.

Good service from start to finish. When our furnace wasn't working properly we called Lakeside Heating. They made it easy to schedule a quick appointment. The serviceman was on time and professional. He found several issues. Since the furnace was 16 years old it wasn't worth repairing. Lakeside provided five written quotes for a new furnace the same day.

Since we haven't every purchased a new furnace we took several days to research our options. We then got several other quotes. Lakeside Heating had the best price and quickest installation scheduling. The installation crew showed up on time, did a good job, and explained everything. Later I couldn't get the digital thermostat app to work on my phone.

The president of Lakeside Heating took the time to walk me through it on the phone and had me up and running in a couple minutes. Lakeside Heating is getting all our future heating and air conditioning business.

This is the 2nd home we have used Lakeside Heating & Air Conditioning to upgrade our 20+ year old furnaces and AC. We may have to buy another house just so we can use them again. Bill, the owner is very knowledgeable in the latest equipment. He took a lot of time working with us and answering questions to ensure that we got exactly the system we wanted.

We were looking for high efficiency. He was able to offer that and was able to balance efficiency with sizing the system for our application and at a reasonable price. It is amazing how much better this system works. It is so quiet we barely hear it running but the house no longer has cold spots and is able to maintain even temperatures. He was highly flexible in terms of installation because we had a major remodel going on and we wanted things done in a certain order. He and his team are reachable, which is a nice change. We know that if we have any issues or want additional work, they will be there for us.

I cannot say enough good things about Lakeside Heating & A/C. I originally called Tony to for an estimate to replace our geriatric furnace and also add A/C. He gave me all the options and I promptly rolled them around for over a year - periodically emailing to ask questions (which he would gladly answer) and get an updated quote. Right when we decided to table it until our main floor remodel was underway, the furnace kicked the bucket during a snowstorm on New Years Day. Lakeside was our first call and both Bill and Tony were so quick to track down the heat pump we wanted in another state, get it moved to CO quickly, update our quote for the 6th or 7th time and, in under a week, we had a shiny new Duel Fuel system. The technicians were very communicative and skilled. Our inspector said "Oh yeah, Lakeside always does great work". Happy to recommend Lakeside to everyone!

Lakeside Heating was responsive from the first call for an estimate all the way through installation of the new furnace and final inspection. It is a pleasant experience to have them be honest, on time and be professional in every way. There customer service was beyond our expectations.

I just wanted to take the time to give a great shout out to this place. It's so hard to find good service these days, but Lakeside really has a steady and reliable pattern of good service. I have them out every year to clean and service my furnace before I use it for the winter and they also installed my new hot water heater about 6yrs ago for 1/2 what some of the other places were quoting for it.

I also just spoke on the phone with Bill today (it's only a couple of days after Christmas, so it's nice he's so available). I had some questions about noises that my hot water heater makes and got some nice reassurance that it's all fine and running properly. I just so appreciate Bill taking the time to talk with me, brainstorm issues and ideas around the questions I had, and be so understanding about my concerns. I highly recommend this place. It's great as it is.

We had heating system and AC system replaced. I would rate the two installers that carried out the scope of work as highly professional. They stayed focus on the job, brought all the necessary equipment and supplies with them (no trips to the store for spare parts, etc.). They kept the work area clean through out the two days. At the end of the job both my wife and I were given a review of the work done in the work space and a very clear explanation of how to operate the new thermostat.

Prior to the job; we were given numerous options for both heating and AC equipment. Other quotes typically gave us quotes for one system that 'they' thought would be the best fit.

Tony was very professional and straight forward with answers and expertise on furnace systems that would work best for us within our budget concerns. Mick and Brandon installed the selected unit and were punctual, friendly and definitely qualified as they did a fantastic job on the install and cleaned up the area, hauling away all old equipment and container materials such that you would never know they were there! Very professional installation. Excellent company to do business with.

It is always such a pleasure to work with Lakeside heating and cooling. Tony gives so much good information so that the perfect unit can be chosen. We were able to get our install two months sooner than predicted. The staff who takes the calls are professional and helpful, the install was seamless. Mick was great and very professional. Lakeside heating and cooling Installed a heater for us five years ago and we were very happy with the quality of their work. They came and did a tuneup and I loved that also. Can't say enough good about this quality company.

Great people! They replaced my condo furnace and AC units. Chael and Derick were professional and explained every step of the way. Lakeside heating are the company to use for HVAC issues. Thank you to all. It is so much quieter in my condo, thanks to the new unit. ***Not sure about the extended contract, Comfort Shield Contract. What is the cost of this contract?

It only covers the labor and not the parts for a needed repair. I do not recall anyone discussing this contract with me and neither does my husband. ** Hope to hear back from Lakeside soon concerning this issue.

This review was overdue, but still want to give a feedback. I appreciated the work they done for me being professional and did a great job with the work that they do. My house never had an AC but choosing them were the right company to get one. I am happy and satisfied. Thanks (In Aurora) Service: AC installation

These guys installed a new furnace and new a/c in my townhouse. I purchased a new property and the existing was old and original. I love my new thermostat and the A/C is working great, so nice to control it from my phone. Saved a nice amount to pay for it all upfront by check. Purchased the Daikin system with a 12 year warranty and bought the narrow A/C so it doesn't take up very much room and is super quiet when it runs. Haven't used the heat yet but that's just around the corner. Very pleased with my purchases!

Wow is all I can say. As someone said, "Tony without a doubt is the man!" And I would have to agree. They came and installed a mini-split system in our home. Mick, their installer, is the man! He was very professional and friendly. He answered all my questions and concerns. His assistant Brandon was also very professional. The installation went without any issues.

We are very happy with the installation and product (Daiken). Though we did get it installed right after the hot weather cooled, I have to say the heat on these works fantastic! The price and service was well worth it. My husband and I couldn't be happier. We'll be excited to try the ac next summer as the two window units were barely keeping the house at a toasty 83 when it was 95 out. Thanks so much for the wonderful service!

From start to finish, this team had a lower price than the competition, & did everything as promised. The installers kept us up to date on what would happen & when it would happen. At completion, the operation was explained, everything was cleaned, their drop cloths covering our oak flooring were removed. Fantastic A+ service & people. Can't go wrong with this this first class company

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.

Tony, without a doubt, is the man! Actually, everyone he employs "is the man". Just spent $13,000 on a whole new system and couldn't be happier. If you have a problem, they will fix it. Thank you Tony and the crew for making my life good again. The wife is happy and my house is happy! Choosing Lakeside Heating & Air is always good. You won't regret it.

My whole experience, from quote to install was excellent. Tony graciously answered all my questions professionally. They were not my lowest quote, but not far off and instilled a sense of confidence that they would do an excellent job. Mick and Brandon, did the install carefully and competently. An extra thumbs up to electrician Mike for going the extra mile to route the power wire internally rather than going completely around the house with external conduit.

I've used these guys for a while now. They have done a few maintenance items and a repair for me in the past. Most recently I had a new system installed. While they were not the cheapest, you get what you pay for. High quality equipment and service. Mick did our install and he was absolutely fabulous. Super friendly and patient with all my questions. About a week in and everything is running great, and I feel confident that if there are any issues they will be right out here to fix it.

Lakeside came out to the house today and provided superior service and a detailed explanation of what I needed to get my furnace operating at peak efficiency. Lakeside will be the only HVAC company I use from now on.

My first experience with LH&A was when I purchased a rental property that had previously had a service contract with them. I decided to keep them for the HVAC at that house since they were already familiar with the boiler and had also installed the air conditioning there. I was so impressed by the experienced old school service technician that I started using them for my own house as well. I support reputable, locally owned businesses and this one has been around since 1971.

Called to get a quote on installing a house humidifier and was disappointed to hear they won't install other's products. This didn't make sense to me as they don't manufacture the products. I told them I already had the unit and simply said that they won't install other's products and abruptly hung up. Unfortunately for them they had no idea we also needed a new furnace as well. These guys had great reviews but my first impression of customer service from this company was less than impressive.

I would definitely recommend this local, family owned company. Our furnace went out and we initially called a different company which claimed we needed various new parts which would total about $1400, and recommended we get a new furnace. Called Lakeside the get a second opinion and they came out and fixed the furnace the next day for only $250 and told us we in fact did not need those extra parts that had originally recommended for repair!

Our technician, Tony was very professional and had the new part put in and our heat back up and running within an hour. It's nice to see that there are still nice, honest companies you can trust in the HVAC industry.

We used Lakeside to replace a central A/C unit, and were entirely satisfied with their service. When they came out to bid the job, they were patient and knowledgeable, answering all of our questions while walking us through our different options. A/C units are expensive, and we appreciated the information and competitive pricing Lakeside provided.

The Lakeside team that installed the A/C unit was also top notch. We chose a system that is new to the U.S. market (Daikin), and were pleased that Lakeside was a certified installer for the brand. (Only a couple companies in Denver are certified, and the first company that bid the job made us feel icky.) There's something to be said for supporting family-owned businesses, and we will definitely recommend Lakeside to anyone in need of A/C services.

Lakeside heating did not follow through with their contract to install a boiler that they stated they would install in my home. When the installation crew arrived they did all they could do to avoid doing the work. The crew leader took the position that I did not choose the "right" equipment for my home and that I would need to excavate part of my yard and dig out the crawl space in order to install the equipment that the owner and sales person had instructed them to perform.

It was obvious to me that the scope of the work was too complicated for the installers to perform and they needed to find a reason not to do the work, so they blamed me the homeowner for their lack of knowledge as the equipment was available to manage all of their complaints but they were not interested in trying to problem solve the situation but were interested in not doing the work they had agreed to install at a very high price which I had agreed to initially. Lastly I as the homeowner I was not consulted regarding their decision to refuse to do the work they had agreed to perform, the problem was that the installers were not capable of reading the manufacturers installation instructions which contradicted their decision and the parts were available to facilitate the installation.

Overall Lakeside wasted over a week of my time while we had no heat! I found a competent company in Aaark Companies and they did a great job with courteous employees and professional communications and problem solving that included me the homeowner and customer. I probably need to state the house was a rental with the tenant freezing while this was all transpiring. I installed the least expensive solution rather than have the tan ant freeze!

Lakewood continues to get a 5 star rating. Since furnace installation I have requested 3 service calls basically routine maintenance and to put protective cover over the thermostat. Great service and availablity. I am pretty clueless on these matters but I don't have to worry because they know their job so I dont have too: Prices are fair and they stick to their quotes.

Had a pretty big job replacing an old, gas forced air, huge furnace. The gas lines in the house went right through the middle of the room. Mick was my installer, and he really went the extra mile in finding a better path to the new furnace, that wouldn't interfere with the room as much. He added a vent that could be opened in the furnace room, as it's shared by the washer and dryer and it could be nice not freezing, when going down to do laundry.

The new ducting setup really has changed the comfort level of heating throughout the house. It's just the first night with the new furnace, but I'm very happy with the quality of product, and professionalism I received over the last two days, especially from Mick.

Lakeside Heating and Air Conditioning is an amazing company. We thought that our air conditioner had met its end but the technician told us not to worry and fixed it easily with a $200 part. Our house is now cool and I am beyond satisfied. Lakeside is an honest company who went above and beyond to help us. I'm so thankful!

When I mentioned to a coworker I was in need of a new furnace, she recommended Lakeside. I got several estimates from other companies and Lakeside offered me different Lennox styles with reasonable prices. After considering what would work best for me, I decided to go with Lakeside. Everything went very smoothly from the first appointment with Tony, the install itself, the financing, and finally, today the city came out and inspected the job. I hope this Lennox lasts as long as my old one!

Lakeside installed my a/c a few years ago and was the most prompt and professional company I received an estimate from. They have since come out to repair my furnace, again prompt and professional. I can not recommend Lakeside Heat and Air Conditioning enough. The $95 charge others are referring to seems a standard same day charge that any company would similarly charge for an "emergency" visit. The two times I have needed them quickly, they have come through within the hour. This is what you are paying for.

I had Lakeside come out to give me a second opinion on my furnace. I was told that it needed to be replaced. Tony came out and found that there was only a minor issue with the furnace and it was relatively easy to fix. They performed the work and my furnace has been working flawlessly ever since. They saved me from needlessly replacing the whole unit. Thank you guys- you are now my go-to company!
