The winter season can be a bit tough on the HVAC systems. There is no surprise that the demand for HVAC systems and repairmen increases when the temperature drops below freezing. So, if you already own an HVAC system or are about to buy one, here are some common problems in the winter you should keep in mind and have HVAC repair services inspect your unit ASAP.
Thermostat issues are among the most common HVAC problems in the winter. Although this is not common with new units, older units tend to struggle. From outdated thermostats to faulty wiring, extreme temperatures can take a toll on the components inside and impede performance.
If the thermostat is malfunctioning, you will experience inconsistent temperatures. Moreover, the screen of the thermostat may go blank if the batteries need replacing. It could mean that the thermostat needs calibration. In such a case, you will need to consult an expert to fix the issue.
CO does not hinder the performance of an HVAC unit but its existence is very harmful. CO is a colorless and odorless gas that can wreak havoc in the house if exposed to for long periods. Furthermore, inhaling CO can also lead to chronic health problems.
The best way to ensure that CO does not harm your family members in case of a leak is to open the windows to allow ventilation and make sure the vents and chimneys aren’t blocked. If you notice that you are experiencing headaches, dizziness, confusion, and difficulty in breathing, it most probably means there is a CO leak somewhere.
If detect a CO leak or smell anything weird, turn off the HVAC system immediately and call an expert to determine and fix the leak. On top of that, you should also install CO detectors on every floor.
Clogged Or Dirty Air Filters
No matter how much it is stressed, air filters are mostly ignored by homeowners without realizing that it could cost them a lot in terms of repairs and replacements down the road. Air filters are designed and installed inside the HVAC system to purify the air before it is distributed inside the house.
With time, it turns dirty or becomes clogged due to dirt and dust, etc. This is why experts suggest cleaning the air filters at least once a month and replacing them once or twice a year depending on the usage frequency.
Even though every manufacturer recommends more or less the same changing interval, you should consult the user’s manual to maintain a consistent replacement or cleaning schedule.
Flickering Pilot Lights
Flickering pilot lights is another problem with central heating systems in the winter season. There are two primary reasons for flickering pilot lights. First, is the drafts that can cause the lights to flicker and go out. You need to ensure the vent cover is attached correctly and the flame sensors are not clogged or damaged. This could also cause the pilot light to go out. Depending on the situation, the flame sensor should be cleaned or replaced.
Frozen pipes can be a serious headache as the days and nights grow colder. If you have a system that uses steam and hot water circulation, then the situation is going to be even worse. Frozen pipes need to be dealt with immediately as pressure buildup can cause them to burst.
If you notice decreased water pressure, condensation on pipes and odd odors from the drains, etc. it most likely means you have frozen pipes. If that is the case, you should shut off the water supply. Try raising the temperature using heating pads, towels, or even a hair dryer.
Depending on the temperature in your area, you may need to do it regularly. The sunny days may help bring down the ice but when it’s snowing, you will have to put in the extra effort.
In the end, HVAC problems in the winter should not be that serious if you were to prepare yourself before the season. And once winter arrives, make sure you look after the system and clean and maintain it to prevent any complications throughout the season.
