I recently had the original home Swamp coolers and furnace(s) replaced with new Coleman refrigerated Air / Furnace(s) at my house. I choose B Carlson after obtaining several different estimates and ultimately picked B Carlson because they provided the best overall value (balance of price, equipment design, and technical knowledge of what the project required). The team installing the units were fantastic - Dave / Chris went out of their way to ensure the existing equipment was removed carefully and cleanly (cleanup everyday was immaculate). Likewise, on the installation it was clear David was a perfectionist and spent the necessary time/effort to ensure every part was perfect and to ensure the installation was flawless. This was a fairly big job and Dave and Chris worked tirelessly to get the job done correctly and on the promised timeline! Fantastic work by the team and i could not be more happy with the quality/workmanship.
