- SWShane WieselerFeb 19, 20264.0Kevin and his assistant were very helpful and knowledgeable about the issue. Kevin explained everything that he was doing and checking. After Kevin explained what he was doing he would ask if I had questions. I would recommend Kevin to anyone who needs heating and cooling problems.
- PRPaulette RaymondFeb 17, 20265.0THIS IS ACTUALLY A 10 STAR REVIEW...5 stars for Ken and 5 stars for Kellen, who were a great team and replaced our furnace and AC yesterday. Both young fellas were courteous, respectful and very helpful in patiently answering all of our questions about our new Lennox system! I am sure that Kalins recognizes how valuable these knowledgeable representatives are to their organization!
- MWMichael WeltzFeb 15, 20265.0We couldn’t be more impressed with our new HVAC system and the installation process. Danny and Nick arrived right on time and completed the entire job before the end of the day. Their attention to detail and quality of work is beyond expectations. They did a lot of re-ducting/customization of our existing ductwork which looks professionally done.
- SVStephen VermeerFeb 14, 20265.0Everyone at Kalins that we worked with was great! Adam and Jeremy for inspection, Fernando for maintenance, Josh salesman, Kenneth, Kellen and Anthony for removal and installation of new units. Courtesy, respect, professionalism describe them best. Couldn’t ask for better service from these guys. Thank you all for such a great experience.
- MBMichelle BainbridgeFeb 11, 20265.0We couldn’t be more pleased with the 2 young men who put in our new furnace and ac! They were very professional ! Had all the equipment they needed even down to the dirt to put under the air conditioner to make it level! Cleaned up everything in the end and made sure all our questions were answered. Highly recommend Kalins!! Thanks a bunch!
