At Glendora Hills AC and Heating, we help families in San Dimas, CA stay comfortable with honest HVAC service, clear pricing, and quality workmanship backed by real experience.

We are a family-owned HVAC company with a small, skilled team and 55 years of combined hands-on experience. Our motto is Comfort of the Foothills, and that is exactly what we aim to deliver on every visit. Whether you need air conditioning repair, furnace service, seasonal maintenance, or a full system replacement, we take the time to inspect your equipment, explain your options, and help you make the right choice for your home and budget.

We know San Dimas homes

San Dimas has a great mix of older homes, established neighborhoods, and newer properties. That means HVAC needs can vary a lot from one house to the next. Some families deal with aging furnaces, weak airflow, hot upstairs rooms, or rising energy bills. Others want to upgrade to a high-efficiency air conditioner or heat pump to improve comfort and lower monthly utility costs.

Because we work in this area, we understand those common problems. We look at the age and condition of your system, check performance, and give straightforward recommendations. If a repair makes sense, we will tell you. If replacement is the smarter long-term move, we will explain the benefits, warranty differences, and expected energy savings in simple terms.
