As soon as the cold weather hits, having a fully functioning furnace becomes top priority. However, because your furnace likely hasn't been turned on for quite some time, you may be unsure of how it is going to function for you when you do actually turn it on. Luckily, there are certain signs that you can look for that may indicate that your furnace is in need of a repair. Here are three signs to watch out for.
The idea of a furnace getting too hot seems a bit far-fetched, but a malfunction can easily cause it to operate well beyond safe temperatures. This can lead to a whole host of problems ranging from premature heat exchanger failure to an actual fire and resulting damage.
If you suddenly smell hot metal, burning rubber or melting plastic from your furnace, then there's a good chance you're dealing with an overheating issue.
Investing in simple HVAC repairs is always smart. You don't need to spend a lot of money or do much technical work to dramatically increase the efficiency of both your heating and air conditioning. Not only that, you can usually improve the quality of air that is being circulated in your home. This is especially important if there is anybody in your household who suffers from allergies. Perhaps the easiest, and most important, DIY job you can do to improve air quality and airflow is to clean your air registers.
