When Your System Quits at the Worst Time
HVAC never fails on a mild afternoon. It fails on the first 100-degree day of the summer or the coldest night of the winter, usually when you have people over. Modern Air is built for exactly those moments: a real person answers the phone around the clock, and no-cool and no-heat calls go straight to the top of the schedule.
We have run this way from our Morgan Hill shop since 2009, and our reviews are full of last-minute saves.
A real person, 24/7
You will not fight a phone tree or wait for an office to open. Our phones are answered day and night, so whether your AC dies at dinner or your heat quits at 2 a.m., you reach someone who can help. We give you an honest arrival window, not a vague promise.
Same-day service, most days
We keep common parts on the truck so many repairs are done in a single visit, and we do our best to reach you the same day you call. One customer’s AC failed right after a July 4th power outage and we had it running again the next morning, holiday weekend and all. Another lost heat and had a technician out the next day with the part already in hand.
Priced upfront, even in a crisis
Urgency is never an excuse for surprise pricing. Your technician finds the problem, explains it in plain language, and gives you a written price before any work begins. If a simple fix will get you comfortable again, that is what we will recommend. Diagnostics start at $110, and our HVAC cost breakdown lists the usual repair ranges so a 2 a.m. quote is not the first number you have ever seen.
Once the crisis is over, the fix belongs to a service: no-cool calls are AC repair, no-heat calls are furnace repair, and the way to stop being in this position next season is two tune-ups a year on the maintenance plan.
When the house is too hot, too cold, or something smells wrong, call or text Modern Air at (408) 497-0444. We answer 24/7, we prioritize emergencies, and we quote the fix before we start.
Frequently Asked Questions
Do you offer 24-hour emergency HVAC service?
A real person answers our phones 24/7, day or night, so you can always reach us. We prioritize no-heat and no-cool emergencies and get a technician out as fast as we safely can, often the same day.
Can you come out the same day?
Most days, yes. We do our best to get a technician to you the same day, and emergencies get priority on the schedule. In peak heat waves the calendar fills fast, so the earlier you call or text, the better.
What counts as an HVAC emergency?
No cooling during a heat wave, no heat on a cold night, a burning smell, a system that keeps tripping the breaker, or water leaking from the unit. If it is not safe or not livable, treat it as urgent and call us.
What should I do while I wait for the technician?
Turn the system off if it is smoking, sparking, or leaking water, and keep everyone away from it. On no-cool days, close the blinds and stay hydrated. Our team can also talk you through a safe quick check over the phone.
Is there an extra charge for emergency or after-hours service?
We will always tell you the fee before we roll a truck, with no surprises. Your technician gives you an upfront, written price after the diagnosis, so you decide before any work begins.
