What breaks when the cold finally shows up in Alton
Anyone who was in Alton during the February 2021 freeze remembers it. Heat pumps ran for days without a break, heat strips pulled more power than tired breakers could handle, and rolling outages kept knocking systems off and on. Equipment that had barely been used in years got pushed past its limit in a week.
That is the thing about heat in the Valley. It sits idle most of the year, so problems hide until the one week you need it. A weak capacitor, a burned strip element or a sticky reversing valve will not announce itself in August. Heating repair Alton families schedule before the first norther is a lot calmer than a call at 6 a.m. on the coldest day of the year.
Most Alton homes heat with a heat pump. Heat pump not heating? The usual suspects are a stuck reversing valve, a failed defrost board, low refrigerant or a thermostat set up for cooling-only equipment. In defrost mode a heat pump will briefly blow cooler air and the outdoor unit may give off steam. That is normal. Cold air for an hour straight is not.
Heat pump repair starts with a full diagnosis. If the unit is near the end of its life, our heating installation team in Alton can quote a replacement. Read more about how heat pumps handle both seasons.
Behind the heat pump, most air handlers carry electric heat strips for backup. Heater not working at all? Strips are a common culprit: a burned element, a tripped limit switch or a breaker that cannot hold the load. Those are straightforward fixes once we find which one it is.
Some homes have a gas furnace instead. Furnace repair covers ignition, flame sensors, inducer motors and limit switches. Whatever the setup, heater repair follows the same rule: diagnose first, quote second, fix third. Our heating repair service page covers the full list.
We are not a 24-hour shop. What we offer is fast service during business hours, a callback within five minutes and priority for homes with no heat on a cold day. If you need emergency heating repair or emergency heat pump repair, call as early as you can. We are open 7:30 a.m. to 7 p.m. on weekdays and 8 to 5 on weekends.
If someone in the house is elderly, very young or sick, tell us when you call. And if you are searching heating repair near me late in the evening, leave a message and we will call you back.
Some no-heat calls are not the equipment at all. A disconnected duct in the attic dumps warm air where nobody feels it, and a thermostat set up wrong can lock out the heat strips. We check both. If the ducts are the problem, our duct repair and replacement work fixes it, and a properly configured smart thermostat for Alton homes runs the heat pump and strips the way they are meant to run.
The best fix is the one you never need. A fall heating maintenance visit tests the strips, the defrost cycle and the safety controls before winter.

Answers for Alton homeowners whose heat picked a bad day to quit.
It may be the defrost cycle, which is brief and normal, or a reversing valve, refrigerant or control problem. If the cold air lasts more than a few minutes, call.
A faint dusty smell for a few minutes the first time each season is normal. A strong electrical smell, smoke or a smell that lingers is not. Turn the system off and call.
Yes, along with heat pumps and electric heat. Anyone searching furnace repair near me can call and get service within 24 hours.
Make sure the thermostat is set to heat and above room temperature, check the breakers for the air handler and outdoor unit, and look at the filter. If all three look right, call.
Often, when the schedule allows. Same-day and next-day appointments are common, and no-heat calls on cold days move up the list.
It depends on the problem, so we quote after diagnosis. The service call covers travel, diagnosis and a full evaluation, and it is discounted once you approve the estimate.
If it is under about 10 years old and the problem is a part, repair usually makes sense. An older unit with a failed compressor or a big leak usually points toward replacement. We give you both numbers.
Yes. Weekend hours are 8 a.m. to 5 p.m. on Saturday and Sunday.
