"Had two gas water heaters go out simultaneously. I called Baker Bros ijn the evening and had a technician the next day. He quickly diagnosed the problem and replaced the heaters. My sons were thrilled to have hot water, and the rest of us were thrilled they were able to bathe again."

"The installation itself went well, and the additional items promised were received. We negotiated for more items since we didn't need an additional RO filter. NOW here is the BUT. We do have satisfactory whole house basic filtration, BUT it adjusts the pH the wrong way for us. Sales person tested water but I don't think she was used to seeing high pH like we have out here. We really needed a different solution to take care of that, but that wasn't suggested. So our water is even softer now. This keeps us from being satisfied with what is a good product otherwise. Last periodic servicing January 2017, satisfactorily performed."

"Stuart HVAC, LLC Was amazing.  Stuart's knowledge, professionalism and attention to detail saved me time and money.  The man really knows his AC and heating.  He did so well on my air-conditioning system replacement that I had him come back out and replace my hot water heater.  All of which are working perfectly! 
I would recommend him to anyone who is seeking an honest, hardworking and skilled person in this area.
Regards,
Leslie

"Checked the entire house and water heater.? We discussed the water in depth, it would need to be replaced in the next year and it was 10 years old, at the end of it's life.? Adjusted all toilets and installed two new flappers, so the toilets don't run constantly and saves water.? Checked the shower and replaced the shower head.? We were entirely satisfied with the service."

"A contractor I’ve been doing business with contacted Lonnie early Tuesday morning to perform plumbing services related to a broken water pipe. While at the house he: made a thorough inspection of all areas showing damage, and replaced a length of copper pipe with (far superior) pex pipe. The copper pipe had burst during the freeze of January 2024. He was diligent and careful to remove only those portions of drywall and other materials to evaluate the extent of water damage. Along the way, he made (plumbing-related) suggestions that would ultimately be money-saving. For example, he suggested getting a tankless water heater and tomorrow, he will install an icemaker connection box for our refrigerator. Lonnie is very professional, knowledgeable and personable. He provides excellent plumbing services and he places them far above profit. I highly recommend him."

"I Highly Recommend Stacy Calahan at Calahan Construction & Air! It was in middle of summer 2019, hotter than you can imagine inside my house even with 2 portable a/c units running in LR trying to mitigate some of the heat while waiting on my a/c company to help me. I found Calahan Construction & Air... Stacy came out quickly diagnosed the problem right away, my unit was dead (I had been nursing it over last few years) but I couldn’t purchase a new unit until I got in a place to fund a house remodel. So, I needed a used 5 ton unit - not an easy ask, but Stacy found one and installed it w/in 24 hours for a price that did not break the bank (about the same cost as 2 top of the line portable air conditioners, which I returned!) He was professional, responsive, and quick at a reasonable price! Stacy listened to me, took ownership of my problem, was kind & caring and best of all got the job done quickly at a price I could afford...all in the middle of summer (his busiest season) when other air conditioning companies are charging premium prices or up selling, Stacy Callahan got me what I needed not what he could sell me! His work ethic & business model are heads and shoulders above the rest, do not hesitate to use this company for all your A/C needs!!"
