Central heat is a great way to keep warm during the cold days of winter. It’s also an affordable alternative to installing separate furnaces in your home. Central heating also comes with some significant downsides, though. For starters, it doesn’t work when you’re away from home. Even worse, when central heat breaks down and starts blowing cold air instead of hot air – the whole house remains freezing for quite a few days before someone manages to repair it. If you recently started experiencing similar problems with your central heating system, rest assured that you’re not alone! Luckily, there are simple solutions for resolving this issue as well!
Why is my central heat blowing cold air?
There are a variety of reasons that your central heat may be blowing cold air. One of the most common is that the temperature setting is set too low. If your thermostat is set below the temperature you would like it to be, the unit will continually turn on and off, resulting in cold air being blown throughout the room. Additionally, if your system is not properly sized for your home, it may not be capable of heating the entire space.
How Does Central Heating Work?
Find your home’s heating requirements
Before you can decide what kind of central heating system is right for your home, you’ll have to know how much heating you need. There are calculators online that can help you find out exactly how many BTUs your home will need. To make sure you have the right amount of heating for your home, take note of your home’s square footage, the number of people who live there, and any pets. If you live in a climate that gets especially cold, or if you have a home with higher ceilings, you’ll need even more BTUs to keep warm. Be sure to factor in any seasonal weather patterns, too. If there’s a chance you may need to turn your heating system on in the spring, summer and fall, you won’t want to install a system that’s too powerful.
Find the right location for your furnace
There are two common locations for a furnace: the basement or the attic. If you choose to install your furnace in the basement, you’ll have to make sure it’s protected from flooding. A flood-resistant furnace is recommended by the Environmental Protection Agency. If you choose to install your furnace in the attic, make sure your home has plenty of attic space. If not, you may need to make some renovations to install your furnace correctly. You may also need to hire an electrician to install a new circuit breaker.
HVAC installation and ductwork
HVAC installation is something that should be left to licensed professionals. You’ll have to decide whether you want a standard furnace or a hybrid-gas furnace. Hybrid-gas furnaces are more expensive, but they’re more energy efficient and less noisy. You’ll also need to choose between a single-stage, two-stage and variable-speed furnace. The right choice for you will depend on your home’s heating needs. A single-stage furnace is the least expensive option, but it’s not energy efficient. A two-stage furnace is the most expensive option, but it’s the most efficient. A variable-speed furnace falls in the middle. Next comes ductwork, the part of your HVAC system that brings the warm air from your furnace to the rest of your house. It’s important to make sure your ductwork is adequately sealed and that it’s not overheating. For best results, hire a professional to inspect and make any necessary repairs.
Furnace installation
You’ll need to find a place that’s convenient to install your furnace. Ideally, you’ll want to install it close to an electrical outlet and a water source. If you’re installing your furnace in the attic, you’ll need to make sure there’s an opening big enough to fit the furnace. You’ll also need to make sure you don’t block any air vents. Each type of furnace has its own specific installation instructions, so make sure you follow them carefully. If you’re installing a gas furnace, you’ll also need to purchase a CO detector for added safety.
Duct sealing and airflow testing
The best way to improve your home’s central heating system is to seal any leaky ductwork. You can do this by taping any gaps with foil. You can also use a sealant or spray foam for added protection. To test the airflow in your house, place a fan outside your ductwork. You’ll then want to observe the speed of the fan and the sound it makes. If the fan is spinning quickly and making a loud noise, it means there are too many leaks. If you find any leaks, seal them with duct tape.
Thermostat installation
Before you install your thermostat, you’ll need to find out what type of wiring your home uses. You can use an online wiring plan to help you determine which circuit breaker controls your furnace. Once you know the circuit breaker you should use, you can choose the right thermostat. There are many types of thermostats to choose from, including digital thermostats, programmable thermostats, and touch-screen thermostats. Programmable thermostats are hands down the best option for central heating systems. They allow you to customize your house’s temperature settings and save you money on energy bills.
Final checkup and quality assurance
It’s important to make sure your home’s HVAC system is running efficiently before winter arrives. You can do this by checking the filter on your furnace, keeping it clean, and replacing it every three months. You should also make sure your HVAC unit is running at the right speed for your house. Next, check the pressure in your HVAC system and clean your furnace filter. You can also schedule a professional cleaning, which will help your system run more efficiently.
What Is The Reason My Central Heat is Blowing Cold Air?
1. Damaged or dirty Air Filters
If your air filter is damaged, you will end up with a system that blows cold air. You can tell if your air filter is damaged simply by looking at it. If there are holes in the fabric, the filter will be ineffective and the system will blow cold air.
2. Dirty Blower Motor
If you have a dirty blower motor, it can make your central heat system blow cold air. To check this, do a visual inspection of the blower motor. Remove any dust or dirt from it and see if there are any broken or missing parts. If so, replace the blower motor and make sure to clean it regularly as well.
3. Damaged Electrical Wiring
If you find that your central heating system is blowing cold air despite having an efficient filter and clean blower motor, then it may be due to damaged wiring. This is most likely due to a loose connection somewhere in the electrical wiring of your home’s HVAC unit or furnace room itself. Switch off all electrical devices in your home and check for loose connections in the light fixture where you switch on/off the HVAC unit as well as any other wires that may be touching other wires on their way to their destination. If there are problems with any of these connections, they should be fixed immediately so that you don’t end up with a cool system blowing warm air instead!
4 . Low Voltage Power Supply
If you find that your central heating system is blowing cold air despite having an efficient filter and clean blower motor, then it may be due to a low voltage power supply. This is most likely due to a loose connection somewhere in the electrical wiring of your home’s HVAC unit or furnace room itself. Switch off all electrical devices in your home and check for loose connections in the light fixture where you switch on/off the HVAC unit as well as any other wires that may be touching other wires on their way to their destination. If there are problems with any of these connections, they should be fixed immediately so that you don’t end up with a cool system blowing warm air instead!
Conclusion
That’s all you need to know about central heating systems. The bulk of this article focused on the downside of central heating: it breaks down and blows cold air. The good news is that there are solutions to this issue. When your heating system breaks down, remember that there are a few quick fixes you can try. If those don’t work, make an appointment with a heating repairman.
FAQ’s
Q. Why is my central heating system blowing cold air?

If the electrical wiring in your home is damaged, then there will be a problem with the blower motor. This can be caused by a loose connection or by wearing out parts of the motor. The good news is that there are fixes for both of these problems, so if things start to get too cold in your home, you should be able to fix it quickly!
Q. How do I know if my central heating system needs repair?
A. It’s important to have a professional check out your central heating system before you call for service from an HVAC repairman. If you have any concerns about whether your HVAC system needs repair or not, then it’s best to contact an HVAC contractor first before calling for service from another company or trying some quick fixes that may damage your equipment further!
