Arizona may see plenty of sunshine throughout the year, but this doesn’t mean it’s sweltering all the time. There are days when it can get pretty cold, especially during the fall and winter. This may encourage you to switch on your furnace or heat pump for a change — except the system is blowing cold air while in heating mode. What exactly is causing this issue, and how do you deal with it? The trusted heating and AC replacement company in the area, Cool Zone Air Conditioning and Heating, answers this and more here.
Your Furnace Hasn’t Completed the Heating Cycle Yet
It can be a bit worrying to feel cold air blowing from a furnace that’s in heating mode. But before calling your local HVAC technician for the necessary solution, give the system a few more minutes. Like bringing a kettle to boil, this doesn’t happen instantly, especially, if the furnace hasn’t been used in a while. Before it can blow hot air, the heating cycle needs to warm up, which should take about 10 to 15 minutes. If nothing changes, there may be an issue somewhere else.
Your Thermostat Was Incorrectly Programmed
Thermostats offer a simpler and more convenient way to control your home’s indoor temperature. By allowing you to program your HVAC system’s performance based on your lifestyle or schedule, you get to instantly experience optimum heating or cooling to your desired level — all while helping keep energy costs down. The thermostat is also integral to heating or AC maintenance, so check it first when your furnace or air conditioner isn’t working.
Perhaps another family member changed the thermostat settings and forgot to set them back, or maybe the thermostat is still set for the previous summer. Whatever the reason, all you need to do is change it to the settings you generally use for colder months. Did it work? If not, there may be a problem with the thermostat itself.
Cool Zone Air Conditioning and Heating, a heater and AC replacement specialist, can help you with this. We’ll take a close look at your current thermostat and depending on what we find, we’ll recommend the necessary fix. If your device is outdated and failing, we offer advanced Wi-Fi thermostats from the trusted industry name, Carrier®. They give you full control of your home’s comfort, allowing you to adjust the temperature, humidity, airflow, and ventilation with just a touch of a button. The best part is you don’t even have to be at home to do it.
The Furnace Filters Are Dirty and Clogged
Dust, dirt, dander, and other debris gets caught in the furnace or heat pump filters over time. When overlooked, they create blockages that not only hamper the way hot air is distributed throughout your home but lead to poor indoor air quality as well. As the congestion limits the airflow to your furnace, the system may overheat and turn off, causing it to blow cold air instead.
Fortunately, dealing with the issue is simple enough that you can do it yourself. Just turn off the furnace or heat pump and then check the filters. If they’re dirty and clogged, remove them from the air handler and replace them with new, clean ones. Heating and AC repair experts recommend changing the furnace or heat pump filters every three months. But if you live with furry pets or a family member who suffers from asthma or allergies, you might want to change the filters more often. Once the task is done, you may notice a positive difference in the furnace airflow; it may start blowing hot air instead of cold again!
The Ductwork Has a Leak
Your furnace sends hot air throughout your home via the ducts. Holes and gaps can also develop on them, either because of damaged seals around the joint connections or from rodents biting or clawing at them. Hot air can leak out of the ductwork because of these openings. Instead of reaching the vents and registers, it will blow into unused areas, like the attic or crawl space. This not only results in poor and uneven heating performance but can lead to higher heating costs.
If you suspect leaks in the ductwork, turn to AC repair company Cool Zone Air Conditioning and Heating immediately. We’ll have our trained and experienced technicians perform a comprehensive inspection of your air ducts, identify the leaky areas, and seal them as necessary. With our team ready to deliver effective solutions, you can expect your furnace to continue providing the reliable and efficient heating performance you’ve come to expect.
The Condensate Lines Are Clogged
Most high-performance furnaces have condensate lines, which work to move water and moisture away from the system. When the condensate lines become clogged, the issue stops your furnace from igniting, causing it to blow cold air out of your vents and registers. You’ll need to have them checked by a local HVAC contractor to clear away the blockage and pinpoint any other problems the condensate drain lines may have.
The Gas Supply Has a Problem
Here’s another possible reason for the cold air blowing from your furnace: the gas supply was turned off. If you’ve just had the gas valve or gas supply line fixed, whoever did the work may have forgotten to turn the gas supply back on. Make sure to check whether this was the case. If not, the actual issue may be with the gas supply. After all, most furnaces shut off when there’s a gas supply problem. Do not mitigate this on your own – call a trusted professional as soon as possible.
The simplest way to avoid heating problems like these is to schedule a regular furnace or heat pump inspection and tune up with a premier HVAC specialist like Cool Zone Air Conditioning and Heating. Our friendly and professional techs will diagnose the issue quickly through a precise and comprehensive inspection. And when given the green light, we’ll perform the necessary repair and maintenance solutions, ensuring that you can make the most out of your heating system’s life and performance.
