Lakeside worked to get us taken care of in a timely manner. Very professional and they did an excellent job swapping out our water heater after our basement flooded. Highly recommend!

Quality business - good to work with from quote thru install. Installers were pleasant, efficient and capable - took good care of our house and drop cloths and booties during install and the finished job looks professional. Quoted us what was needed, informed us of options and maintenance items but no pressure or upselling in the process. Would recommend them to others.

Lakeside HVAC did a great job evaluating our existing system and providing us with a new efficient furnace and AC. The installation team was friendly, on time, and answered any question we had. The left the furnace room clean and tidy after the install. A great experience and the best price and product for our needs.

Lakeside Heating installed our new furnace and AC. Their quote wasn't the lowest, however, the offer of 5 years with 0% financing was hard to beat since not many people have $10K+ in the bank. Tony was very professional, knowledgeable and quick with the many quotes we asked for. Holly was very nice on the phone when filling out the financing application and scheduling the appointment. Speaking of the appointment, they were able to come install within a couple days of saying "yes" to the quote, which was great! Mick and Brandon did the install of the new equipment and were very friendly and professional. It was quoted for 2 days of work and they were done in a day! Overall, great experience and would recommend them to friends and family.

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.
