Common HVAC Problems and How to Fix Them
Your HVAC system goes through a lot each year, from keeping you warm during the frigid winter months to cooling you down in the blistering summer heat. With this system working practically 24/7, it’s only a matter of time before it requires maintenance and repairs. In this blog, we’ll discuss the frequent HVAC problems homeowners face and DIY fixes that can keep your home comfortable and save you money. We’ll also cover when to seek professional HVAC repair from a trusted technician.
Common HVAC Problems
Insufficient Heating or Cooling
Several issues can cause an HVAC system to not adequately heat or cool a home. A faulty thermostat, dirty filters, or refrigerant leaks could all be the cause of a poorly performing HVAC unit. This can make it difficult to accurately pinpoint the cause, though there are some things you can try before calling a professional. Double-check the thermostat to ensure it’s set to your desired temperature and mode. You can also check the air filter and replace it if it’s dirty. If these quick fixes don’t help, there may be a more serious problem with the unit that requires professional attention.
Unusual Noises
Unusual noises coming from your HVAC system, such as banging, whistling, or rattling, might indicate loose components in your HVAC system or issues with the ductwork. Turn off the unit and inspect it to see if you notice any obstructions or debris caught in the fan. You can also look for loose bolts, screws, or leaks between ductwork components that are within reach and easy to tighten. If the strange noises continue or you’re unable to find the source, contact a professional for a more in-depth inspection.
Frequent Cycling
If your HVAC system cycles too frequently, you could end up with a steep energy bill and a home that is perpetually too hot or too cold. This is a common issue if you have an oversized HVAC unit or an improperly placed thermostat. For example, if the thermostat receives direct sunlight for most of the day, it might constantly activate the A/C, even if the rest of the home feels cool. A simple fix is to adjust the thermostat lower or higher to trigger the unit less frequently. However, if the issue persists, you may need to consult a professional HVAC repair company for evaluation.
High Energy Bills
An unexplained high energy bill could signal that you have an HVAC issue. Perhaps the system is not working efficiently, or your home has poor insulation and doesn’t regulate temperature properly. Seasonal HVAC maintenance and energy-efficient assessments can help you maintain proper system performance and quickly address any emerging issues causing it to work inefficiently. This will help you extend the unit's lifespan and avoid more serious and costly repairs from neglected maintenance.
Poor Air Quality
Dirty filters or blocked air ducts can lead to poor indoor air quality. This issue can create an uncomfortable living environment and exacerbate respiratory problems for those with asthma or allergies. Replacing a dirty air filter is a simple task you can handle on your own. However, cleaning out ductwork can be a bit more tricky, so it might be worth hiring a professional to do it every few years.
When to Call a Professional
Certain HVAC issues have easy DIY fixes; however, more complex repairs require intervention from a trusted professional HVAC repair company to ensure the system’s safety and integrity. This includes issues like:
