Lakeside Heating and A/C, really outstanding!

These guys were great! From the initial consultation and estimate through the install. They were fast, efficient and knowledgeable. They got the estimates back to me on the same day as the consultation. Their installers were great too! They did a great job taking out the old dinosaur and vacuuming up everything, including dog hair, before installing the new furnace. The new furnace is excellent. My last furnace was a Lennox and it lasted 44 years! That is why we went with a Lennox again.

Just the Best from Start to Finish.

From the quote process to the installation, these guys were the best contractors I have ever worked with. Honest, reliable and fair prices.

Great Service

I used this dealer to install the heating and cooling system in a new home I just completed. I was pleasantly surprised by the installation quote. All work was completed on time. They have returned on two different occasions to answer questions and adjust the system. I am very pleased with the service.

Great Experience

I had a great experience with Lakeside. They were able to get me a great deal on a great furnace and AC unit. They also worked with Excel Energy to maximize my rebates. They were very professional and did a fantastic job on the installation.

Excellent Dealer

From the time I submitted my request to bay a new furnace in the company website I received a call from the Lakeside and they schedule an appointment to come and check my needs in details. They helped me with practical and excellent solutions to improve my heating and cool system as well and their proposal includes all details of work. In addition to the professional services, Lakeside helped me with the all paperwork’s need for the permit, rebate and financing.

Won the bid after five other companies estimates

I was initially impressed by the professional way the estimate process began. They provided a folder with all the BBB information, references, product information, and how to accept the bid. You would be surprised how many other dealers did not provide this during the estimate process!

The individual, I think may be the owner, was friendly and knowledgeable. Friendly…but not chatty. As a customer, I did not want to hear anyone’s life story or tell mine. The other companies spent more time chatting than telling me about their product and service.

The quote was not the lowest, but very reasonable. Getting a % off for paying cash was great! I loved the fact that Lakeside is a family owned business. I accepted the bid and emailed the estimate form in. Another nice factor that made this process smooth sailing.

Lastly, the service installers were friendly, efficient, and did their job well. The gentleman took the time to show me how to set the thermostat. Lennox is a name I recognized and the guarantees were reassuring.

I will recommend Lakeside to friends and family.

Professional and Courteous

“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.”
– Gene B. – Lakewood, Colorado

Very Happy Customer

“We love Lennox and Lakeside Heating & A/C! This is the second home we have had Lakeside install Lennox products and we are always completely satisfied. The Lennox furnace is wonderful and heats beautifully but is also super efficient. The people at Lakeside are all professional, extremely knowledgeable, courteous and helpful, and they truly know the Lennox products inside and out. Even after the install, any time we call Lakeside they are right there to help.”
– Erin Q. – Denver, Colorado

Helpful and Quality Install

“Lakeside Heating staff and installers were always professional and courteous. They went out of their way to explain every detail to us. After installation, the installers walked us through all the steps on how to change the filter and how to work the electronic thermostat. I was very impressed by Lakeside. The office staff associate, Holly- was always friendly and returned my calls or concerns in a timely manner. The office staff also helped us with getting our rebates and warranty paperwork. They were great and I am definitely referring them business in the future. As for Lennox products themselves, their reputation as a strong quality product has always stood out to me. The fact that I chose Lennox products was a no brainer to me. My family has always had Lennox air conditioning and furnace equipment.”
– Erin Q. – Denver, Colorado

Met me on the Weekend

“Bill – Thank you so much for your willingness to help me out on a Sunday with your great advice about “defrosting” my air conditioner coils. I left the air off with only the blower running as you said and the AC appears to be working properly now. I already knew your company was the best in terms of customer service but you have proven it to me again today. I’ll be calling for my furnace check-up early this fall. Thanks again and I’ll try to do a better job of keeping up on my furnace filter changes.”
– Lynette M. – Denver, Colorado

High Quality Install and Products offered

“I shopped around extensively and went with Lakeside for several reasons. They sell high quality A/C units, have a solid installation crew, and offer attractive financing options. Having worked in the home improvement industry myself for over five years, I expect a lot of builders / installers / contractors. Simply put, these were the best contractors I’ve worked with and set a standard others should imitate. The sales staff communicated the features, benefits and pricing well. The office staff kept the project on schedule. The installers were punctual, clean, trustworthy, and efficient. Definitely a five star experience.”
– Scott L. – Denver, Colorado

Amazing Family Owned Business

“Bill Carey, William Buras, and Bill Carey’s grandson, Tony were excellent in each phase of the selection and installation of our new furnace, air conditioner, air filtration system and air duct cleaning service. Beginning with Bill Carey, he arrived at our home listened carefully to the things that we wanted in our heating/cooling unit, discussed the pros and cons of each of the products, then made recommendations that were designed to address the needs that we had identified. In addition, he carefully and respectfully address questions that arose from other bids on the job. Installation was done to perfection over a two-day period.”
– Sharron O. – Arvada, Colorado

Amazing Owner and Helpful

“First of all my experience with William on the phone was excellent. He was able to answer my questions about the process, about the products and about his experience with problems such as mine (hard wood floors are shrinking due to the dryness from heat in the winter time). My 2nd experience was with the installation guy (Raphael) who was: 1. On time, 2. Knowledgeable on the product he was installing and on all the pieces of equipment already in my furnace room. 3. Answered all my questions and said he’d have their office folks follow up with me on future cleanings and checkups on my system. I would recommend these guys to anyone!!!”
– Charles L. – Denver, Colorado

Amazing Communication

“Very thorough and communicated well with us through the whole process. This was for our rental home. Now that we have been trained on how to program our rental property’s thermostat, we know how to use our new home’s unit better! Thanks Lakeside – well done!!!”
– Arvada, Colorado

Highly Recommended

“I highly recommend these guys. They did a fine job. The design engineer came to the site and provided a written quote with several options detailed. He then coordinated a mutually agreeable time frame for the installation. All work was completed on time and the crew did an excellent job of cleaning up their work area after completing the install. I would highly recommend this firm for additional work!” – Littleton, Colorado

No Sales Hype

“I didn’t get a lot of “sales hype” from Lakeside. They gave me an estimate, not a sales pitch. That was nice. I also liked their customer service both at the office and the installation itself. I believe in supporting locally owned business and these guys have been doing this for decades. I found their installation team to be quick and clean.”
– Ellen T. – Broomfield, Colorado

Thank You

“Very professional and respectable. Up front and honest as well as well informed and knowledgeable. Highly recommended.”

Overall AMAZING!

“Just the best experience – everyone was professional, friendly, on time, and accountable. I really enjoyed working with all of the team members – love the fact that it is truly a locally owned, family business. I would highly recommend this company to anyone.”
– Jill M. – Denver, Colorado

Great Dealer

“The representative that came out for the estimate was very professional and upfront. I decided to go with Lakeside because the warranty on the unit was better. That was really my only deciding factor between them. All were very professional and it was a very hard decision to make as to who to go with. Thank you!”
– Linda L. – Arvada, Colorado

Quick Communication

“Quick to contact for an estimated. Fair and informative estimate visit. Next day install on purchased Furnace and A/C. Exceeded expectations due to honesty of recommendations, fairness of price, and speed and quality of install.”
– Littleton, Colorado

Very professional presentation

Work was done without any problems. Area was cleaned up after the project. Completed as scheduled. On time and courteous staff during all encounters. No hidden costs in the estimate. Very complete and there were no surprises. Thank you!”
– Beth L. – Arvada, Colorado

“Greetings! Today you visited our property at 4107 Winona to resolve a furnace issue, specifically fan replacement. My partner Mike Crisman called you when I let him know that I referred you to one of my real estate clients, Contessa and Kim Hardman, and they had a good experience with your company. We appreciate your honest assessment of the problem, letting us know it was just a fan that needed to be replaced instead of telling us the entire unit needed to be replaced. If we do need a new furnace at one of our rental properties in the future, we will be calling your company. In the meantime, I’ll be referring your company to every client, friend and relative that I come across. Thank you.”
