Heating & AC Repair

Fullerton Heating & Cooling Services

Professional HVAC Technicians Proudly Serving Orange County

Southern California has a reputation for having a temperate climate with mostly ideal temperatures. However, Orange County’s dynamic landscape can cause temperatures to climb to well above the 100s in the summer, and fall to biting lows in the winter. As a result, a properly functioning heater, ventilation, and air conditioning (HVAC) system is an essential utility for Fullerton residents. At Dial One Sonshine, our reliable team of HVAC professionals can tackle any job, from simple routine maintenance issues to major overhauls and installations.

Heating Services

Whether your residence is kept warm using a furnace, boiler, or another system, Dial One Sonshine is prepared to resolve any issue with your heating system. Fullerton residents can count on us for repairs, maintenance, and system replacements. If your heating system is operating at less-than-optimum levels, you can schedule an inspection and have our one of heating technicians examine your system and identify the problem

Air Conditioning Services

Before people changed its landscape, Southern California was a natural desert. Today, intense heat waves continue to serve as a reminder of California’s naturally punishing climate. As a result, a smoothly running air conditioning system is vital for the comfort and wellbeing of Fullerton residents. Our team of professional air condition technicians can quickly repair or install an air conditioning system. You can also avoid major issues from developing with our year-round preventative maintenance plans.

Air Quality Services

Studies and inspections have demonstrated that the indoor air quality of the average home is lower than that of the outdoor air, even if large metropolitan areas. A person who has a health condition that is sensitive to differences in air quality would greatly benefit from having a clean, well-working ventilation system. Dial One Sonshine’s professional team of air quality technicians can clean and repair old air ducts. We can also replace and install electronic air filters, UV air sanitizers, and humidifiers or dehumidifiers to help promote your family’s health.
