John Johnston A/C & Heating

John Johnston A/C & Heating operates out of New Braunfels, Texas as a local HVAC outfit focused on keeping homes comfortable through the area's brutal summer heat and occasional winter cold snaps. John Johnston serves as owner and installation manager, handling the day to day work of getting systems up and running for homeowners who need reliable cooling and heating without delays. New Braunfels sees plenty of calls for units pushed hard by high humidity and temperatures that stay above ninety for months, so the crew stays ready for whatever breaks down in single family houses and older properties around town.

They handle full air conditioning installations, furnace repairs, routine maintenance checks, and emergency service when a unit quits on the hottest day. Financing options help customers avoid putting off upgrades to more efficient equipment that cuts monthly bills, and the team shows up with the right parts to fix problems like failed compressors or weak airflow instead of pushing unnecessary replacements. Work happens on rooftops, in attics, and at supply connections, with attention to getting the job done right the first time so homeowners do not face repeat visits during peak season.

Customers keep coming back because the crew moves fast on repairs, delivers solid quality that lasts through Texas weather, keeps prices straightforward without surprise add ons, and answers questions clearly during the whole process. That steady performance across dozens of jobs adds up to a strong reputation in a trade where timing and follow through matter most. DIRT Score 4.3 from 67 reviews on Finds.

“This company has really changed. Once the new owners bought out the previous owners everything went down hill. This place is no longer about the customer but about the dollar. The staff is great and well informative. I would recommend switching supply houses. Many others are cheaper and actually care about the customer. Greed is the downfall of this once great company.”
