Retrofitting – the process of bringing old AC and heating systems up to code and making them work more efficiently- is one of our specialty areas. San Diego’s historic neighborhoods have their own set of requirements when it comes to air conditioning, heating and ventilation. The original architecture of vintage and historic homes is not capable of accommodating pre-fabricated systems that many HVAC companies offer; Carini Heating, Air and Plumbing has the solution based on your home’s specific needs. Owners of historic properties in the San Diego area, including Kensington, Mission Hills, North Park, and La Jolla, where the homes were constructed between the early 1900′s and the 1950′s will benefit from our specialized air conditioning and heating systems and retrofitting services. Owners of historic properties have been so pleased with our work that entire neighborhoods have turned to us for their retrofitting needs.
