The rainy winters in Greenwood can be bleak. So, it can be daunting when your HVAC breaks down unexpectedly. It is, therefore, essential that you learn to detect problems with your equipment. There are issues, such as thermostat settings, that you can take care of yourself. Here are some tips for troubleshooting your heating system.

Insufficient Heat From the Furnace

If the airflow is constrained, your AC may fail to heat parts of your home sufficiently. Two of the most striking problems are a clogged filter and obstructions to the registers and vents.

At Complete Comfort, we always recommend cleaning or replacing the filter at least once a month. If your home in Greenwood has many occupants or pets, you may have to do it more frequently. Pet dander, debris, and dust can quickly make your system inefficient at regulating temperatures.

If you’ve been replacing your filter, the next step is to check if the vents or registers are blocked. Furniture, fabrics, and other household items may be obstructing airflow, which can raise the air pressure within the duct. When it gets to a certain level, it may damage the ductwork and cause leaks.

You can consult a Complete Comfort technician to inspect your system for signs of leaks or clogging. Our staff can clean and fix your ductwork. We recommend scheduling maintenance for your ducts every three years. Not only will it boost efficiency, but it can also restore your home’s indoor air quality.

The Furnace Is Short Cycling

Your furnace may turn on and off as it attempts to heat the interior of your home. Short cycling may be due to wrong settings or a defective thermostat. It’s always wise to start by checking the thermostat configurations before attempting other troubleshooting steps.

Start by making sure the device settings are set to heat. You can turn up the temperature on the thermostat by about 5 degrees and check if your system is still short cycling.

Another problem could be the location of the thermostat. Some areas of your home may be exposing it to high temperatures from sunlight or appliances. Heat sources such as space heaters, ovens, and electronics will give the device false temperature readings.

Dust on the thermostat may insulate components, preventing it from accurately regulating heat. You can use a soft brush to gently wipe away dust from the device’s contact plates and metal coils.

If those solutions don’t work, you may want to consult a certified technician to troubleshoot your system. It could be that your HVAC isn’t the right size for your home. Complete Comfort will evaluate the installation and provide solutions to restore the function of your system.

Cold Spots in Your Home

Your HVAC system may be heating your home, but there may also be cold spots in some areas. The most likely reason is that airflow isn’t getting to all the parts of the house. When that happens, the ductwork may be leaky or damaged.

The problem may arise if you’ve recently added an addition that requires heating. The system may fail to heat some areas as its capacity diminishes. One way to get around this problem is to use a ductless mini-split system. They are efficient and won’t require extra ductwork to extend heating to other rooms in the house.

The best option is to call our technicians in Phoenix to evaluate the heating load. It involves an analysis of your ductwork and insulation levels to determine the source of the problem. Insufficient or substandard insulation may cause an imbalance in temperature regulation.

Unusual Noises From Your System

If your HVAC is faulty, you may hear unusual noises coming from the equipment or ductwork. You ought to know what the sounds mean so you can act when there is a fault.

Rattling noises may be a sign that there are weak connections and components. It’s also possible that the cover panels are loose and need to be tightened. Unsecured wires and electronic parts within the system can be dangerous to your equipment and safety.

Another type of sound you may hear is squealing. The high-pitched noise is a sign that your blower motor belt isn’t aligning correctly with the blower. Your belt could be worn out and may require a replacement.

Grinding noises are a sign that the motor bearings are defective. If you keep the system running, it may cause further complications in your equipment. You can turn off the HVAC and call our technicians for assistance.

If you hear popping sounds coming from your equipment, it may be an indication of expansion as temperatures rise. If the noise persists, it’s a sign that there’s a pressure difference within the duct. Ensuring your ductwork is clean and insulated may solve the problem.

Unpleasant Odor From Your HVAC

Don’t ignore any foul smell coming from your furnace. It can point to different faults that could put your HVAC at risk of total system failure. Some odors can pose a health risk for your Greenwood home.

The smell of burning metal, wood, or plastic is usually an indication of overheating. It’s most likely due to an electrical fault, which can cause residential fires. Issues to do with electrical components can be dangerous to fix. When you notice that type of odor, switch off your system and call a Complete Comfort technician in Greenwood.

You should note that your furnace is likely to smell when you start it after a long time. If you still notice a burning odor from your system after 24 hours, your unit may have a technical problem.

A musty smell is caused by the accumulation of moisture within your heating system. When moisture combines with heat, it accelerates the growth of microbial organisms. Our technicians can check your ducts and equipment for signs of condensation during maintenance.

Our team can present you with solutions to address the risk of microbial growth and the spread of contaminants. UV air cleaners can kill microbes as they go through your HVAC system. We have other products that can reduce the risk of respiratory problems and allergies.

A distinct smell of burning plastic may be a result of a foreign object getting into the system. When plastic burns, it releases toxic fumes that pose a threat to humans, pets, and the environment.

Another type of odor you should pay attention to is rotten eggs or the smell of hydrogen sulfide. Natural gas is odorless and colorless, but it has chemicals added to it to make it easier to detect leaks.

If you use a gas furnace and notice the smell of rotten eggs, the best thing to do is switch off the system. Also, if you’re unsure about any troubleshooting step, you should avoid tampering with the equipment. You may cause damage that could be expensive to repair and may cause injury or health risks.
