Like many homeowners, you probably don’t think about your HVAC system until it’s not working properly. This is usually because of the discomfort that comes with it. As a rule, you should be checking your HVAC system regularly or whenever you’re handling your periodic home improvement projects to avoid problems and ensure optimal performance. Below, we will discuss nine common causes of HVAC problems so you can prevent them from happening in your home.
Faulty Wiring
The wiring that connects your HVAC system can easily go wrong, especially if it’s not well-maintained. When this happens, it can cause all sorts of problems with your heating and cooling. Be sure to check the wiring regularly and have any issues fixed as soon as possible. Seeking a reputable air conditioner service can save you a lot of time and money in the long run. Hire one when you need any wiring repairs or replacements.
Dirty Air Filters
One of the most common causes of HVAC problems is dirty air filters. When your air filter is clogged, it can restrict airflow and cause all sorts of issues with your system. So, be sure to check your air filters regularly and replace them as needed.
Low Refrigerant Levels
Your HVAC unit will most likely stop working correctly if it doesn’t have enough refrigerant. The low refrigerant levels can cause the coils to freeze and the compressor to overheat, compromising the normal operation of the air conditioner. If you notice your unit isn’t cooling your home as well as it used to, check the refrigerant levels and have them topped off by a professional.
Dirty Coils
The coils in your HVAC system can get dirty over time, which can reduce its efficiency and cause it to overwork itself. To prevent this, ensure you clean the coils at least once every year, depending on the size of your unit and how frequently you use it. You can do this yourself or hire a professional to do it for you if you’re unsure of your DIY skills or are constantly held up with other issues. Another option for you is to take advantage of your HVAC Coverage if you have one.
Thermostat Sensor Problems
Your HVAC system’s thermostat is responsible for telling the unit when to turn on and off. If the sensor isn’t working correctly, it can cause your unit to run constantly without ever reaching the desired temperature. You can test the sensor yourself by moving it to different locations in your home and seeing if the temperature changes accordingly; if it doesn’t, it may be time to replace the sensor.
Leaking Ducts
If your ductwork is leaking, it can cause all sorts of problems with your HVAC system. The most obvious problem is that the air supposed to be going into your home is escaping through the leaks. This can lead to higher energy bills and make your home less comfortable. You might also notice that your system isn’t working as well as it used to or that certain rooms in your home are harder to cool or heat than others.
There are a few ways to fix leaking ducts, including sealing the leaks with mastic or metal tape and installing new ducts. If you have a lot of leaks, it might be easier (and more cost-effective) to replace your entire ductwork system. However, the best way to go about this is to hire a professional to do it for you. They’ll be able to assess the problem and give you the best solution.
Clogged Registers and Vents
If you have clogged registers or vents, it’s probably because your HVAC system is too big for your home. When an HVAC system is too big, it doesn’t run as efficiently as it should and can cause several problems, including clogged registers and vents.
One way to solve this is by having a professional come out and do a load calculation to determine the right size system for your home. You could also adjust your thermostat settings to help alleviate the problem.
A Bad Capacitor
Your HVAC system has a capacitor that helps it start up. If this goes bad, it can cause all sorts of problems, including your system not starting up at all. The only way around a bad capacitor is to replace it with a new one. You can easily do this alone or hire a contractor to do it for you. A professional is better placed to do the work faster and more effectively. They can even fix other problems your untrained eyes couldn’t pick out regardless of the type of HVAC system you’re using.
Failure of Electric Controls
This is a common cause of HVAC problems, particularly in places that experience power surges frequently. The good news is that it’s usually an easy fix; all you have to do is replace the part that has failed. You can also check the compressor and the fan controls if they’re still in great shape or if the consistent power surge problems already wear them out.
When you call a professional to have a look, ensure they check all contacts and electrical connections to ensure there’s no such problem recurring in the future.
HVAC systems are vital in every home, office, and many other buildings. It would be best to know about the common causes of HVAC problems to ensure that your system is always in tiptop shape. By being vigilant and regularly checking your system, you can avoid any significant issues and save on repair costs in the long run.
