Signs You Need Furnace Repairs

Sometimes it’s pretty obvious when your furnace needs a little love and care, but sometimes the signs can be hard to read, if you don’t know what you’re looking for. Our experts came up with the most common signs to watch for that signify you may need repairs:

  • Your furnace refuses to kick on. This may be obvious, but it bears mention simply because there are loads of possible issues here. An unresponsive furnace could be due to thermostat issues, faulty wiring, busted components and many other common problems.
  • Your furnace is making odd sounds. You’re probably familiar with the minor sounds your furnace makes during operation. But if you notice a clunk, bang, wheeze or whistle that seems out of place, it’s a good idea to get ahold of a professional immediately. These are commonly signs that components have broken loose, and may further damage your furnace if left unhandled.
  • Spikes in energy costs. A little variation is natural, but when your utility costs spike a good ten to twenty percent for no obvious reason, you likely have an issue that needs addressing with your furnace.
  • Your thermostat is unresponsive. Often a wiring or electrical component issue, if your thermostat doesn’t seem to register adjustments you make, or the displayed temperature doesn’t seem to accurately reflect the temperature of your home, it’s time for repairs.
  • Overfrequent ‘kicking’ on and off. If your furnace is operating erratically, or over frequently, there is a good chance something has gone wrong. In some cases, this issue could necessitate a replacement.
  • Air quality is becoming an issue. If your allergies are acting up a bit more than usual, or you note a heightened presence of dust in the household, the ductwork of your furnace may be at fault.

Amazing work by this tech. He was able to diagnose and resolve a faulty HVAC installation (performed by a competitor company), which had resulted in massively sweaty (condensation-soaked) ducts. He was knowledgeable, highly skilled, efficient...,and a very cool guy. Highly recommended.
