Winter is quickly approaching, and with it comes cold weather, snow, and high winds. You may have to bundle up to go outside this season, but you shouldn’t have to bundle up in your own home. An HVAC system has to work hard to maintain the temperature setting on your thermostat. Knowing the signs of an ineffective unit could save you a lot of trouble in the future. By properly taking care of your system, you can ensure that it lives up to its maximum life expectancy (and save you money in the process).

Read on to learn more about some of the signs that can crop up when your HVAC system is in need of repair or replacement.



A dirty or clogged air filter is always a warning sign. Luckily, it is one of the easiest issues you can fix on your own. Simply pull out the air filter to see how dirty it is. If the air filter is clogged, all you need to do is go to the store and buy plenty of replacements. Your air filter determines what kinds of contaminants make it through to your home’s air supply. If you have pets or rely heavily on your HVAC system, you’ll want to change out your air filter every 30-90 days.


Your thermostat runs 24/7 in order to maintain a controlled climate and ensure the comfort of the people living in your home. Like anything else in life, though, it does eventually conk out for good. If you notice inconsistencies in the temperature of your home, your thermostat could be the culprit. If you want to have it tested, you can call an HVAC repairman. You could also have a smart or wifi thermostat installed to help save money on future utility bills.


This is one of the first and easiest to spot signs that something is amiss with your HVAC system. When your bills soar to an exceedingly high rate over the course of one month, it’s time to call a professional to take a look at your system. Depending on the inherent issue, this could be an indicator that your system is ready for a repair–or a replacement.




How old is your HVAC system? While the latest HVAC models are pretty resilient, there is always going to be some issue with the various inner components. Your HVAC system has a lifespan of 10-15 years depending on the conditions it has been through and how well it was taken care of. Maintenance (or lack thereof) on your HVAC system will play a significant role in the functionality of its components.


Aside from maintaining temperature, an HVAC system in good working order should properly ventilate both itself and your home. If you start to notice unusual amounts of dust, dander, or debris floating through the air, it could be time to replace it.


When you turn your heater on for the first time this season, chances are higher that you could smell something burning. This is likely just dust burning off as your system uses parts it hasn’t for a while. The smell should dissipate after a day or so. If it doesn’t, remember, your safety is very important.

Power the unit off immediately to examine it just in case. If any wires are burning or mold is present, these are both health hazards that could potentially require replacement. Contact a professional to come out and examine the system for you and give you your best options.
