If you notice that your HVAC is not running as well as it used to, it may be time to call a professional to take a look.
Some problems may be easy to fix by cleaning filters and coils, but some require professional repair. Do not ignore these problems because they could cost you more money down the line.
Clogged filters

Clogged filters are a common problem in heating and cooling systems. Dirty filters can reduce airflow in the home and affect the efficiency of the HVAC system. Dirty filters also prevent fresh air from reaching the heat exchanger, which can cause it to malfunction.
Dirty filters also make it difficult for the heat exchanger to keep the house warm. If you notice any of these problems, you should consider getting your air filter replaced.
Clogged filters can cause airborne dust and other debris to re-circulate through the home. This is particularly harmful for people with respiratory illnesses and chronic allergies.
In addition, poor indoor air quality can affect your health over time, especially if you have pets and chemicals in your home. Therefore, it is important to replace your filters regularly.
Filters are a critical part of your HVAC system. Proper maintenance of these filters can extend the life of your unit and make it more efficient. When filters become clogged, the air handler will have to work harder to remove the debris, which can increase your energy bill. In addition, it can cause your HVAC unit to shut down too early or overheat.
Clogged filters are one of the most common causes of HVAC issues. When air filters become clogged, they restrict air flow and make the furnace work harder. This causes the HVAC system to work harder than it needs to, causing more costly repairs in the long run. Clogged filters can also impact humidity levels in the home, reducing the overall comfort level.
Clogged filters can also cause short cycling, which means that your furnace frequently shuts off and on. Short cycling will increase your energy bills and wear out components of your heating and cooling system. It can also cause your furnace’s electronic “limit switch” to malfunction and shut down the system prematurely.
Blown fuses

If you have discovered that the fuse in your AC system has blown, it is time to call a licensed HVAC technician. These electrical issues can affect the fuse box, breaker, or central power supply. You can learn more by consulting with an expert. A licensed technician can diagnose the problem and determine the proper course of action.
Fuse issues can be easy to identify, but some are more difficult. If you are not sure which fuse is causing the problem, use a digital multimeter to check for continuity between connection points. The multimeter’s display should show a radio wave symbol when the probes are touched together. Next, place the probes on the connection points of the fuse. The type of fuse unit you have will determine where to place the probes.
A blown fuse can be caused by a variety of factors, including a high-voltage environment. The main culprit is overvoltage, which occurs when the voltage exceeds the normal operating range. The problem may be chronic (high voltages on a continuous basis), intermittent (repetitive surges), or sporadic (frequency fluctuations). Chronic overvoltage can be easily diagnosed, while intermittent overvoltage may go undetected.
While it is possible to replace blown fuses yourself, it is often necessary to have a professional replace them if the problem is more serious. In addition to removing a fuse, a blown circuit breaker can cause the HVAC system to malfunction. In some cases, this can lead to a fire or even damage.
If you see a black flash mark on the fuse, that means the fuse is blown. If you cannot find the fuse, the problem is more likely in the breaker panel. To test the circuit, use a voltmeter. If the voltmeter does not beep, you should call an electrician for assistance.
Leaking ducts

If you notice a smell coming from your HVAC system, it is likely that your ducts are leaking. This problem can spread toxic fumes throughout your home. These toxins come from the outside environment and can affect the health of you and your family.
Also, the air that is drawn into your ductwork may contain chemicals. These toxins can be inhaled without you knowing it. So, if you notice a particularly strong smell coming from your HVAC system, you should definitely check it out.
A professional HVAC technician can use a fog machine to test your ductwork to determine if there are any holes. This is a better option than fogging the attic or basement, which can result in smoke. Also, an HVAC technician will have the right tools to detect a leak with pinpoint accuracy. When you are considering an HVAC repair, remember to ask the company if they have the necessary tools and experience to do the job.
Leaking ducts can be difficult to spot, but the good news is that they are relatively easy to fix. If you have basic handy skills, you can do the work yourself. If you are not comfortable doing the work yourself, you can also hire a professional HVAC technician to handle the duct repair for you.
Clogged coils

If you are experiencing the symptoms of clogged coils, you may need to call a professional HVAC repair service. This problem can be caused by a variety of issues.
First, make sure the air conditioner is clean. If the unit is not, it may have too much debris, which can lead to problems. Next, make sure the coils are properly protected by coating them with an anti-corrosive material.
If you are unsure how to clean the coils, use a vacuum cleaner and a small brush. This will allow you to get rid of surface debris and crevices. You can also use a degreaser to clean the coils. Be sure to allow it to sit before you rinse. If the coils are deeply clogged, a high-pressure cleaning will be necessary.
