Frequently asked questions

How quickly can you get someone out if my AC breaks on a weekend?
Yes, they offer 24/7 emergency service. One customer reported a technician arriving within 30-40 minutes on a Sunday when the outdoor temperature was 113 degrees. Another got same-day service after an after-hours call with a technician arriving first thing the next morning.
Do you replace parts you don't have to replace?
One customer asked for a second opinion after a larger contractor recommended a full unit replacement. Mountainside's technician inspected the system and confirmed it was running fine with no coil leak, so no replacement was needed.
Are your maintenance packages worth it?
One customer with both home and commercial accounts recommended signing up for the maintenance package, saying it will save thousands of dollars over time by catching problems early instead of waiting for breakdowns.
