Holiday HVAC Repair
Thanksgiving, Christmas, New Year's — We Answer
Family's in town. Turkey's in the oven. House is dropping a degree every half hour. The big chains are closed. The small shops are home with their kids. You're staring at a thermostat that says 62 and falling. That's our day. That's why we exist.

Why HVAC Picks the Holiday to Quit
There's a pattern, and once you've worked enough Thanksgivings in Birmingham you can almost set your watch by it. The first hard cold front of the year usually arrives between November 18th and December 5th. That's also the first time most homeowners have used real heat since March or April. Eight months of dust has settled on the heat exchanger. The flame sensor has corroded. The ignitor has microscopic cracks from heat-cool cycles. None of that matters when the house is calling for cool air. It matters the second you ask the system to make heat.
Then add the holiday demand pattern. Christmas Day in Hoover: twelve people in a house designed for four, oven running for six hours, doors opening every time another car pulls up, thermostat bumped from 68 to 72 because Grandma's cold, kids running in and out without latching the back door. Your furnace or heat pump is being asked to do twice its normal work and the weakest part of it gives up.
Same logic flips for summer holidays. July 4th in Vestavia: cookout outside, AC running flat-out, doors propped open for the dog, twenty people inside cooling off between rounds in the backyard. The condenser coil that hasn't been cleaned in two years finally can't reject enough heat, the compressor trips on high-pressure lockout, and you're explaining to your father-in-law why the punch bowl is sweating.
Heat-Side Holiday Failures
The most common Thanksgiving call we run. The ignitor glows orange to light the gas — eight months of off-season has it cracked or burned out. The furnace draft inducer runs, you hear the click of the gas valve, but no flame. Twenty-minute repair when we have the right part on the truck, and we usually do.
The little metal rod next to the burners that proves the gas is actually lit. It corrodes during the off season and stops sensing. The furnace lights, runs five seconds, shuts down — over and over. A few minutes with steel wool sometimes fixes it; replacement is cheap when it doesn't.
The safety that confirms the inducer fan is pulling combustion air. Cracked tubes, clogged drain ports on high-efficiency furnaces, or a failing switch itself all stop the call for heat. Common after a long summer where the condensate drain in a 90%+ furnace dried out and clogged.
Alabama winters cycle around freezing — heat pumps need to defrost every 30-90 minutes when outdoor temps drop into the 30s. A failed defrost board or reversing valve causes the outdoor coil to ice over solid, and the system runs on emergency strip heat that doubles your power bill. We see this every January.
Heat pump can't keep up, so emergency strips kick in — and then never kick off because a relay welded shut or a thermostat lost its outdoor sensor. House is fine, but your December power bill triples. Worth a call even on a holiday so you're not paying for a thousand dollars of strip heat through New Year's.
If you smell gas, get out and call the gas company first, then call us. If the furnace says it's calling for heat but no gas is flowing, the valve could be locked out, a thermocouple gone bad, or the supply pressure dropped at the meter. We diagnose and confirm — never guess.
Summer Holiday AC Failures
July 4th heat plus a dirty condenser equals the compressor's safety pressure switch tripping. System runs ten minutes, shuts down for thirty, runs again. The fix is a coil cleaning plus a refrigerant pressure check.
Memorial Day weekend cookout — the unit's been running hard for two weeks of pre-summer heat. The capacitor that was borderline at the start of May finally lets go on the holiday. Outdoor unit hums but won't start. Quick swap.
Labor Day with the house at 70 and twenty guests inside. System runs constant, dirty filter restricts airflow, evaporator coil freezes solid. We thaw and diagnose the underlying restriction — sometimes filter, sometimes coil itself.
Holidays We Cover
All federal holidays. All state holidays. New Year's Day. Martin Luther King Jr. Day. Presidents' Day. Memorial Day. Juneteenth. Independence Day. Labor Day. Columbus Day. Veterans Day. Thanksgiving Day. Christmas Eve. Christmas Day. New Year's Eve. Easter Sunday. Mother's Day. Father's Day. If your calendar has it marked in red, our phone still rings on it.
We also run the days that aren't technically holidays but matter just as much in Birmingham: the Friday after Thanksgiving when extended family is still in town, the week between Christmas and New Year's when everyone's home from work, Iron Bowl Saturday, the SEC Championship weekend, Mardi Gras week along the coast when half the metro is at the beach. Same phone number, same tech on the other end.

Holiday HVAC FAQ
Do you really work on Christmas Day and Thanksgiving?
Yes. After Hours HVACR runs dispatch every day of the year, including Thanksgiving, Christmas Eve, Christmas Day, New Year's Eve, New Year's Day, July 4th, Memorial Day, Labor Day, and every other federal holiday. A licensed Alabama HVAC technician answers the phone — not a holiday voicemail.
Why does HVAC fail more during the holidays?
Two reasons. First, the first major cold front of the year often hits around Thanksgiving in Birmingham, which is also the first time the heat has run hard since spring. Anything that quietly degraded over summer surfaces immediately. Second, holidays mean a full house — more body heat, more cooking, more thermostat changes, doors opening for guests — and that long high-demand runtime exposes weak parts.
What HVAC problems do you see most on holidays?
First-cold-snap heat failure dominates the Thanksgiving and Christmas calls — ignitor failure, flame sensor corrosion, pressure switch issues, heat pump defrost board faults. The July 4th calls are usually AC-side: weekend party with the house at 71° and the unit can't keep up because the condenser coil is filthy or refrigerant is low. We handle both types every year.
Should I wait until the day after to call?
If the house is cold enough to be uncomfortable, if you have guests staying overnight, if there are young children or elderly family members, or if temperatures are forecast to drop below freezing — call. Don't sleep in a 55° house because you don't want to bother anyone on Christmas. We chose this schedule on purpose. The holiday is exactly when we want to be working.
Is the holiday rate different from a regular call?
Call (205) 994-6402 for current holiday pricing. We provide a written estimate covering diagnostic, labor, and parts before any work begins. Holiday surcharges, if any, appear on the quote you sign — never as a surprise on the final invoice.
