Testimonials

What Our Customers Say

"Our AC went out on the hottest day of summer. AM Heating & Air had a technician at our door within two hours. Professional, knowledgeable, and had our system running perfectly. Can't recommend them enough!"

"We hired AM for a complete HVAC installation in our restaurant. They handled everything from permits to final inspection. The team was incredibly organized, clean, and finished ahead of schedule. Outstanding work."

DR

"Transparent pricing, no upselling, and genuinely helpful advice. They recommended a mini-split for our addition instead of extending our ductwork, which saved us thousands. Honest company you can trust."

FAQ

Frequently Asked Questions

How often should I service my HVAC system?
We recommend servicing your HVAC system at least twice a year — once in spring before cooling season and once in fall before heating season. Regular maintenance extends equipment life, improves efficiency, and helps prevent costly breakdowns.
What are signs my AC needs repair?
Common signs include weak or warm airflow, unusual noises (grinding, squealing, banging), frequent cycling on and off, higher-than-normal energy bills, uneven temperatures between rooms, and excess humidity indoors. If you notice any of these, call us for a diagnostic before a small issue becomes a major repair.
Do you offer emergency services?
Yes. We offer 24/7 emergency HVAC service for urgent issues like complete system failure, no heat in winter, no cooling in summer, gas leaks, or electrical concerns. Call (760) 500-6951 anytime for immediate emergency support.
What areas do you serve?
We proudly serve Carlsbad, Oceanside, Vista, Encinitas, San Marcos, Rancho Santa Fe, and the greater North County San Diego area. Not sure if you're in our service area? Give us a call and we'll let you know.
Are you licensed and insured?
Absolutely. AM Heating & Air, Inc. holds a C20 HVAC contractor license (C20 #1077225) issued by the California Contractors State License Board. We carry full general liability and workers' compensation insurance for your protection.
