Customer Reviews

“Our AC went out on the hottest day of the year — 107°F in Valencia. Apex had a tech at our door within 3 hours. He found a bad capacitor, had the part on his truck, and we had cool air again before dinner. Incredible service.”

“Replaced our 18-year-old unit with a new Lennox system. The team was professional, on time, and cleaned up everything. The new AC is so much quieter and our electric bill dropped $120 last month. Best home investment we made.”

“Called Apex at 8pm when our heater stopped working in December — temps were dropping to 28°F. They came out that same night, diagnosed a faulty igniter, and had it fixed by 10pm. Beyond grateful. Will always use Apex.”

“Apex helped us switch from a gas furnace + old AC to a new heat pump system. They handled all the permits, helped us with the SCE rebate paperwork, and the install was done in one day. Our energy bills are down 30% already.”

“Second time using Apex and they continue to impress. Our Saugus home's AC was short-cycling — they diagnosed a refrigerant leak quickly, fixed it properly, and gave us honest advice about the system's remaining life. No upselling, just facts. Highly recommend.”

“Apex installed a new high-efficiency furnace in our Rancho Vista home. The price was fair, they pulled all permits, and the installation crew was clean and respectful of our home. Warm first winter we've had in years with the old system.”

“Our old AC couldn't keep up with Lancaster summers. Apex sized us for a 4-ton Carrier system that actually works. The crew showed up on time both days, worked efficiently, and left no mess. Our house is finally comfortable in July. Worth every penny.”

“Apex diagnosed our AC issue fast — the capacitor and contactor both needed replacing. Fixed same visit. The tech was knowledgeable, explained everything, and the price was very reasonable. This is my go-to HVAC company in Simi Valley.”

“Had Apex install a whole-home air purifier and UV light system. My daughter has asthma and the difference has been remarkable — fewer symptoms, better sleep. The tech was thorough and explained how the system works. Wish we'd done this sooner.”

“Added a mini-split to our garage workshop — Apex recommended the right size unit, installed it in half a day, and the setup is perfect. Works great in both summer and the cold desert nights. Couldn't be happier with the work.”

“Furnace stopped heating on a cold morning. Apex came out same day, found a cracked heat exchanger — a safety issue. They explained the risk clearly, gave us options honestly, and replaced the unit quickly. Professional from start to finish.”

“Apex handles HVAC maintenance for our Lancaster retail space. Their commercial team is responsive, keeps records, and shows up on schedule. Haven't had an unplanned equipment failure since we started the maintenance contract two years ago.”
