Our a/c went out on the hottest day of the year (of course). I called Bill in the evening and they were able to schedule me in the next morning. Jackson was our technician and was amazing. He fixed the problem quickly and the pricing was beyond reasonable. The whole experience was a 10+ out of 10. Thank you Lakeside A/C! read more

This company installed a new furnace for me several years ago. Technicians were prompt, thorough, and very professional. Pricing was competitive with other quotes received. I trust this company, which is very important! I referred my brother to them and he was also very pleased! read more

In Aug/25, my tenant hired them to fix a disconnected wire and fuse, but the technician left the wires exposed, resulting in repeated squirrel damage. When I called them again, in Jun/26, for what turned out to be the exact same issue, they would charge the high diagnostic fee on top of the repair costs again. Furthermore, they aggressively pushed me over the phone, since I was out of town, to buy a brand-new AC unit. So, I hired another company (All Climate Systems) that properly secured the wires, educated my tenant, and applied the initial visit fee toward the final repair cost. read more

10 stars! Had furnace not cycling properly, throwing out an error code, of course when it was in single digits! L/m overnight to call me next day. Bill from Lakeside called me at 8:00 am, discussed what was going on, he gave me a few steps to complete as diagnostic over the phone. It works! Bill saved me a service call charge for a 10 minute fix over the phone! Knowledgeable, great customer service, didn't charge me a bunch of money, they saved me money!, prompt, been servicing the Denver area since 1971.....why would you need to call anyone else! read more

Joe came for a routine servicing of my heater and humidifier. I always have multiple questions and he patiently answered and explained various functions of my system, allowing me time to write copious notes. He offered multiple ways I can save money for future services, even going on Amazon to show me what parts # to order and what it would cost & why that could be a good option. When I booked the service Marissa (front desk person) helped me in a similar way that helped me decide the installed air purifier is not something I need. But that decision was partially made after she told me the part # I could order to save on servicing it if I chose to activate the purifier. I absolutely love the approach Bill (owner) and Joe have toward their customers and they will always be my go-to company for HVAC services. read more

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. read more

They came out and gave me a quote and then said that they couldn't find any scaffolding to do the job (I waited for weeks while they "searched" for a place to rent scaffolding from), and ended up wanting me to rent the scaffolding to do the work. I called another contractor and they said there was absolutely no need for scaffolding on my house. They did not try hard at all to solve a very simple problem. A simple google search shows you can rent scaffolding from about 50 different places in Denver so it is frustrating that they could not figure out how to get the basic equipment needed for this work. read more

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! read more

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. read more

Called them on a routine cleaning of my furnace I was advised of a gas leak. See posted picture. read more

Becky, your installer said the dogs could not be in the house or outside and needed to be put somewhere else. That's when we said we had no place to put the dogs. Contracted Lakeside Plumbing to install a new heater and A/C unit, walked off the job after 15 minutes because we had 2 dogs. Told us they would not do the work with the dogs on the property. We were not informed of this when we signed a contract. They did not try to work out an alternate solution. They then voided our contract. Our dogs are friendly and even told the workmen when they arrived that the dogs are rambunctious at first but would settle down in about 15 minutes. Would not recommend this company. read more

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. read more

Great company!!!!!!!!!!!!! Wonderful people to work with. Very professional, Tony walked us through every choice. Installers were great. Communication was great. Highly recommend Greg Lubeley read more

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. read more

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! read more

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. read more

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. read more

I love this company. I can't say enough good things about them and their friendly customer service. We had them install an Evaporation Cooler in our home recently and they were so professional while working in our home. Bill that came out to give us an estimate was great. He was honest with us and I felt he knew a lot about the business and what he was selling us, he explained everything to us in a way we could understand. We felt very good in choosing them over another company that came out. They were much cheaper on the same exact unit...they beat the other company by $1,000 (no joke!!) The unit was installed in one day and they cleaned up after themselves...it was like they were not even here. I highly recommend them to anyone needing service or new installation. We will be using them for any future needs. read more

Very friendly, family-owned business. We were impressed right away with their services and professional manner. We just recently had an air conditioner installed and what we were hoping for was good value and service. We had another company come and give us an estimate a few months ago and Lakeside gave an estimate almost $2000 less. The previous estimate included a whole bunch of additional duct work they claimed we would need. Lakeside didn't try to rope us into additional work that was unnecessary and costly. Lesson here: Go with supporting a local business and both service and price will make you happy. read more

Update: Got through to Lakeside today, they sent a technician out within an hour and made the quick and easy fix to get my furnace running again. I was charged the base fee which was very reasonable for the fast and friendly service. Tip: Call during business hours. All of my messages that were left after-hours were ignored. read more

Update to first review (below); sadly had to take off a star. i had a part break and called them and (it turns out new) receptionist was kinda bitchy. Also, she said i would get a call back and i didn't for a week, so i called them. The owner said he very sorry and apologized profusely. He said he would call back once he got the part. ...guess what? never called back, so i called again. He had the part and dropped it off and promised to fix it in the spring (its a swamp cooler so i am not using it. I am sure he will, but it was too much hassle. I have figured out that they are very good at getting your business, but not so great at keeping it. Original review: Very happy with the service, fast install and price. They also called right back when I called them a few weeks later because I thought it wasn't working. Turned out that a house sitter had turned off the water supply to the cooler! I highly recommend them! read more

I purchased a new AC unit for my home and Lakeside was excellent from start to finish. Literally every person with Lakeside I encountered was prompt, courteous and professional in their responses. Some highlights-- 1. They made sure I was comfortable with the quote / contract before signing 2. They respond quickly to email and voicemail 3. They were very competitively priced (within $10 of the quotes from two other companies for the same unit) 4. They were very confident in there unit/sizing recommendations and were able to defend why they recommended what they did 5. They worked with my schedule, arrived on time, and worked efficiently 6. They walked me through all the maintenance and functionality of my unit at completion read more

Lakeside Heating figured out why my air conditioner was not working. Their conclusion: a broken condensor fan motor. They offered to fix it for a 799 dollars flat fee during a heat wave. I subsequently had somebody else analyse the problem during a cooler season, and they concluded that it stopped functioning because an auxilary safety switch that is designed to keep the unit from freezing had broken. This switch is an optional feature in one of the lines, that is not necessary for the unit to function. The switch was initially installed by Lakeside along with the original air conditioner, without me being aware of it. Simply bypassing the switch solved the problem , which cost a fraction of 799 dollars. read more

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. read more

Saddens me to say it, but Lakeside just didn't meet an acceptable performance standard for me. The technician set off CO detectors in my house (OK, I understand, torches will do that) but then he didn't seem aware of the problem until I pointed it out. He also shut off the hot water heater and failed to turn it back on. That meant a cold shower the next days and some time lying on the floor before work to restart it. And he left the worn out boiler parts and other, associated trash around the work area for me to clean up. A little more training, and little more mindfulness is in order here. read more

I am extremely impressed by this company! I was looking to replace an old AC unit and received two quotes from Xcel contractors. Not only did Lakeside come in less expensive, I liked them more! From the very beginning I felt confident working with their team - and did you know - its a family owned and operated company? The salesperson was the company owner and there was no sales pitch, just information given in an understandable, straightforward way. Then the service team was polite, quiet, efficient and neat. They explained what they were doing and why. I think that I finally found a HVAC company that I'll use again and again! read more

Having completed several home projects over the past year, Lakeside Heating & AC was the best contractor I've worked with. Had a big job with a very large old furnace that needed to be replaced to install new central AC. I had a bunch of companies out to bid the project. Tony came out, was great at explaining everything and was very honest and upfront about what was needed. No pressure and very willing to put together numerous bids for differing levels of products with 2 different brands. There are lots of potential combinations with heating and AC equipment so it was nice to have everything laid out with all Xcel rebates already factored in and taken off the top. Lakeside was always responsive by phone and email, gave courtesy calls that they were on their way, showed up on time and were professional. Tony, Adam and Mick were all great. I'm in an old house and they were happy to install things in a way that worked best for the space; for example, they rerouted a gas line to give more ceiling height, which wasn't by any means required but overall made for a much nicer finished product. Having had the system for several months now, I couldn't be happier with the performance. No more cold spots in the house in the winter and really comfortable on these hot summer days. Amazing how much you can have these high efficiency systems on and yet how low the energy bills have been. Couldn't recommend them more! read more

My furnace shut down unexpectedly. Richard was prompt, courteous, got the job done, and was priced very fairly. I highly recommend them next time you have an HVAC issue. read more

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. read more

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! read more

I've had a broken air conditioner for a few weeks, and after my landlord's failed attempts at coordinating a repair, he gave up and dumped the responsibilty on me to get it fixed. I called Lakeside, and they were able to send somebody out the same day. John arrived when they said he would, and he went above and beyond to make sure they were able to help me. My building evidently was inspected by 3rd graders, b/c none of the air-conditioning units on the roof are labeled. So there is no logical or easy way of identifying which compressor/ac thingamagig on the roof corresponds to specific units in the building. This didn't stop John, he took the next hour or so of going on the roof and having me flip breakers, etc...so he could hear which unit might be activating. This exhaustive effort finally paid off b/c he was able to identify mine (and label it), and as a result, fix my a/c. So hurray, a/c is fixed, right? Well, not so fast...due to yet another inspection flaw in my building the area in my ceiling where the fan unit lives hangs too low and close to the enclosure's opening...multiple tries to cover it, resulted in pinched wires, and blowing a fuse, and a myriad of other issues. Now it's getting late on a Friday afternoon, and I've gotta jet, so he says that they'll come back on Monday to fix it up. They called twice over the weekend to check in and see if I could accommodate a repair on the weekend (I couldn't). I called first thing Monday morning, they set an appt that worked with my schedule, came over fixed the problem in under an hour, and didn't charge anything extra. Kudos to John and the Lakeside team for providing great customer service. read more

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. read more

After a short delay due to a measurement error, everything else went very smooth. Their prices were very reasonable. They even beat Costco on price and warranty. Their workers did a clean job and explained all of the new equipment. I had an AC and two Humidifiers installed. A stand for the AC had to be mounted on the roof. The initial measurements were in error. This was noticed quickly by the installers. Bill corrected the error and rescheduled the install a week later. I was very satisfied with the end result from initial estimate to final product.. read more

We had a new furnace installed a few weeks ago and we were very pleased with Lakeside's quality of customer service. I requested an appointment online and within the hour a rep was calling me to confirm my appointment and get any other details about what we were looking for. Within a few days we had the owner at our house to check out our crawl space set up and go through furnace options with us. We appreciated that he was up front with us about the different types of furnaces and which ones would be practical for our needs and layout of our home as well as providing a decent ROI. We agreed on a complete install price at that time and all charges were detailed out. We had our new furnace install scheduled for the following week. Their office called to confirm the appointment the day before and their service guys called about a half hour prior to the appointment to indicate they were on their way. Throughout the day long install the service guys were conscientious about tracking dirt through our home and being considerate of our belongings & cleaned up after themselves. The inspection with the city passed on condition that we have the service guys come back up and attach a gas line that was left hanging. There was no need to have another inspection though. When I contacted Lakeside they had someone out within a few days to quickly do the fix. If your furnace is in a crawl space, make sure they measure your opening prior to the install. Unfortunately our crawl space opening is smaller than the standard size of furnaces these days and so the service guys had to cut the opening a little larger which resulted in us having to get a new door for it. It would've been ideal to have known this prior to the install taking place so that we could've been a bit more prepared. Lakeside pricing was better than quotes I'd received from another area HVAC company - nearly $1000 less for a similar model. A competitive price with a family-run, local business is always great! read more

We needed to get our furnace tuned up and certified before selling our home. From the first call to book my appointment, to the nice receptionist that confirmed my appointment the day before, to the technician, everyone was very friendly and professional. The technician called 30 minutes prior to the appointment and arrived a few minutes early. He took the time to understand what we needed done and explained thoroughly what he found and fixed. Overall, a very pleasant experience ~ thank you! read more

I had an AC Unit that was intermittently blowing warm and cool air. With company coming to town the approaching Monday, I was growing nervous that we would be sweltering and angry right off the bat. Thankfully, I spoke with Bill and he gave me some helpful advice over the phone. After a full defrost cycle and a thorough cleaning, our house is much more comfy. Thanks, Bill! read more

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! read more

My wife and I had several people come by and give us estimates. Lakeside's estimate was at or below the others, and they offered Lennox vs. the others offering Rheem and Goodman. That is enough right there for me. But more importantly, when they came to see our system and make an estimate, the gentlemen did right then, he gave me helpful advice on our current system that saved money (which the others did not), was saddened at the unnecessary things the other companies advised, and did not try to sell me anything I didn't need. He told me, "I wouldn't install anything else here, period." I appreciated his clarity and willingness to provide help regardless of whether or not I purchased from Lakeside. One more thing: he also factored in rebates on the spot for environmental recycling and efficiency, which the others did not. I could not recommend anyone higher. read more

Wonderful people to work with. Very professional! Walked us through every choice. Installers were great. Communication was great. Highly recommend read more

They did an excellent job on replacing our boiler. Their estimate came in $2700 less than the next closest bid. Everyone was friendly and professional and the crew worked quickly and efficiently. I am happy to support a local, family owned business. Very satisfied! read more
