Blowing Cold Air
Is your furnace releasing cold air instead of heat? Cold airflow can usually be traced to one of the following problems:
- Wrong thermostat setting
- Old pilot light
- Weak gas supply
- Dirty filters
- Damaged ductwork
So, how do you identify the problem and solve it? That's where the Red Cap Plumbing, Air & Electric team comes in.
Solution: Furnace Maintenance
Sometimes, fixing a furnace producing cold air is as simple as adjusting the thermostat settings. In other cases, a serious problem with the ductwork or gas supply requires expert repairs. Whatever the issue is, heating maintenance can help. Our knowledgeable technicians will check your system regularly, helping prevent airflow problems before they arise. You can also enroll in our Family Comfort Club for annual heating checks.
Won’t Turn On
From a damaged gas line to clogged air filters, there are several reasons why a furnace may not turn on. In some cases, the problem has nothing to do with the system and the thermostat is at fault. The first thing you need to do is find the source of the problem.
Solution: Check the Thermostat
Before you decide your furnace is broken, make sure you check your thermostat. This device tells your furnace when to activate — if it's blank or not working, the furnace won't know it's supposed to turn on. It may have an underlying issue if the thermostat is fully functional. In this situation, it's best to contact a furnace repair expert to examine the appliance.
If your furnace turns on and off randomly without reaching the desired temperature, it's probably short-cycling. This usually happens because the appliance is overheating, which forces it to shut down. Short cycling can lead to uneven heating, higher costs, and long-term furnace damage when left unaddressed.
Solution: Replace the Air Filters
A furnace might short-cycle because of an installation or thermostat problem. However, in most cases, the issue is caused by a blockage in the system, such as dirty air filters or clogged vents. Cleaning your system and replacing the filters can stop short cycling. At Red Cap Plumbing, Air & Electric, we offer system checks and maintenance as part of our heating services. Whether you need an air filter replacement or a general cleaning, we've got you covered.
A Strange Odor
You might notice a burning smell when you turn your furnace on for the first time after months. Typically, this is because the system is burning dust accumulated over the summer. After a short time, the odor should go away. However, if any strange odors persist, you may have something wrong with your furnace.
Solution: Identify the Odor
A multitude of problems can cause a strange odor coming from your furnace. Thus, the first step is to identify the underlying issue. To do this, you'll need to pinpoint the exact odor. Your furnace may smell like one of the following:
- Burning plastic
- Rotten eggs
Generally, the smell can tell you what the problem is. A musty smell, for example, is often caused by mold growth, while a smoky smell results from a blockage. If you notice a burning plastic smell, there might be an electrical wiring problem. The most dangerous smell is a rotten egg odor, which usually means a problem with the heat exchanger, which can release carbon monoxide. No matter what the issue is, our heating experts can take care of it.
The Fan Keeps Running
A furnace has several moving parts, each of which is integral to the appliance's overall functionality. A fan is one of those essential parts — this element is responsible for pushing hot air out of the furnace and through your home. In a typical heating cycle, the fan turns on and off with your system. In a malfunctioning furnace, however, the fan may run continuously.
Solution: Contact Furnace Repair Experts
If your furnace's fan doesn't stop running, don't ignore the problem. Over time, this will increase your monthly energy bills and damage your system. A continuously running fan is usually due to one of these issues:
- Wrong thermostat settings
- Wiring problem
- Faulty thermostat
- Broken relay switch
- Faulty fan limit switch
The first thing you should do is check your thermostat settings and make sure the fan is not switched to "on." If your settings seem fine, the next step is to contact furnace repair experts like the Red Cap Plumbing, Air & Electric team. Our heating experts will show up according to your scheduling needs and thoroughly examine your furnace. In addition to identifying the issue, we'll outline the solution and offer a fair, transparent rate.
