Heating and Furnace FAQs

How long does furnace repair service take?

That depends on what is wrong. We can quickly address things like replacing a clogged filter or relighting a pilot light. If your thermostat causes your furnace problems, our team can often fix those issues in relatively short order as well—usually less than an hour.

However, some concerns require longer to fix due to their complexity, such as those related to the ignition system, heat exchanger, gas valve or blower motor.

Why is my furnace blowing cold air?

If your furnace is blowing cold air instead of warm air, there could be several potential reasons for this issue.

If you’re lucky, the culprit could be that you have set your thermostat to “on” instead of “auto,” which would trigger the fan to blow all the time, regardless of whether your furnace is on and generating heat. To fix this, change your thermostat setting to “auto.”

A problem with the flame detector or gas supply are other possible explanations for your heating system blowing cold air. You might also have a clogged furnace filter or pilot light issue. These challenges require professional attention from one of our trained HVAC specialists.

What should I do if my furnace won’t turn on?

First, check your thermostat to ensure the batteries aren’t dead and it is on the correct setting. Replacing the batteries and reprogramming or resetting your thermostat are quick DIY fixes.

Beyond thermostats, another common reason your furnace won’t turn on is that it isn’t getting power. Look for a tripped breaker or switch flipped to “off.” You also should change your furnace filter if it’s dirty. Call our furnace repair company if your furnace still won’t turn on. We will repair it or recommend a furnace replacement.

Why is my furnace short cycling/why does my furnace keep turning off?

When your furnace is turning off and on frequently, experts call it short cycling. The most likely source is a clogged air filter causing your system to struggle. Blocked vents result in the same problem, so check those as well.

A faulty thermostat can also lead to short cycling, so ensure your thermostat batteries work and the settings are all correct.

If you’ve eliminated these potential trouble spots but your heating system is still turning off and on, it’s time to call in a professional to diagnose and repair the issue. Home Heating & Cooling provides comprehensive furnace tune-ups for our customers in and near O’Fallon.

Why is my furnace leaking water?

If your furnace leaks, the first thing you need to do is turn the system off and clean up the water around the unit. Then, check the air filter and replace it if it is dirty or clogged with debris.

Reach out to our HVAC specialists immediately to have the problem evaluated and repaired if these steps don’t stop your furnace from leaking water.
