Common AC Problems
Everybody enjoys warm weather. However, when temperatures get too high, most rush indoors and crank up the AC. If your air conditioner is suddenly on the fritz, you might be experiencing one of these problems:
- Dirty air filters: Your AC's filter prevents contaminants like dirt and debris from polluting your air. Over time, the filter can get clogged and limit airflow.
- Refrigerant leak: Refrigerant plays an essential role in your air conditioner's cooling process. If it leaks, you'll experience insufficient cooling and reduced energy efficiency.
- Broken part: Your AC has several internal parts, including fans and a blower motor. If one of these parts breaks, your AC won't just stop working but also make lots of noise.
How to Fix
Has your AC stopped working? The first thing you should do is check your thermostat. When a thermostat breaks, it won't communicate properly with your AC. If the thermostat is working, you should check your air filter next. Clogged filters should be replaced immediately.
If there's nothing wrong with your air filter, you probably have a more serious problem. In this case, it's best to contact an HVAC professional to take a closer look.
Common Furnace Problems
There's nothing like snuggling up to a warm furnace during the winter. If your furnace stops working, however, your home can get quite uncomfortable, and the cold can be hazardous to your health. Here are some common furnace problems:
- Short cycling: When a furnace is too large or overheats, it begins short cycling (or turning on and off at random). This damages the furnace and can increase your energy costs.
- Pilot light issue: You'll find a small blue flame on your furnace. Known as the pilot light, this ignites the furnace. If it's not on, you may have an issue with your gas supply.
- Poor heat: Anything from clogged air filters to malfunctioning gas supply lines can limit heat flow.
How to Fix
Like with air conditioners, the first thing you should do is check your thermostat. Make sure it's set to heat mode, and the temperature is correct. Next, check your power supply to ensure the furnace is receiving electricity. If you're still experiencing furnace problems, the last step is contacting an HVAC professional. After examining your furnace, our team can determine whether you need a repair or replacement.
Common Heat Pump Problems
In recent years, more and more homeowners have turned to heat pumps. Heat pumps eliminate the need for multiple HVAC appliances by performing both heating and cooling duties. However, they're not immune to problems. Here are a few common heat pump issues:
- Poor heating and cooling: Insufficient heating and cooling can be caused by a broken thermostat, a dirty air filter, or electrical issues.
- Short cycling: Like furnaces, heat pumps can short cycle. This is usually caused by getting the wrong size for your home.
- Odd noises: Heat pumps are praised for their smooth operation. You might have a loose or broken part if a heat pump is suddenly noisy.
How to Fix
First, check the thermostat and make sure it's working. If you suspect something is wrong with the heat pump itself, contact a professional. Heat pumps are delicate appliances and thus need to be handled carefully.
Common Air Quality Problems
Most HVAC appliances — including air conditioners, furnaces, and heat pumps — catch contaminants and filter your air. So, if one of these appliances is malfunctioning, your air quality might suffer. More specifically, you may notice one of these issues:
- Increased allergens
- Trouble sleeping
- Mold and mildew growth
When pollutants like dirt and debris are left in the air, they can trigger allergies. Not only does this cause cold symptoms (like coughing and sneezing), but it also disrupts sleep. Poor air quality may also foster conditions that encourage mold and mildew growth.
How to Fix
To keep your air clean, changing your HVAC system filters regularly is important. You should replace your filters every three months and have your entire system checked by an expert professional at least once a year.
