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.

Great Service that exceeded my expectations!!




This is by far the best HVAC company I have used. Erwin was professional, knowledgeable and extremely thorough. He did such a great job that I signed up for their maintenance contract to ensure my systems are always operating at their optimum level.

Terrific and Fast Service




Erwin worked diligently on repairing several aspects of our air conditioning system. He was very professional, showing me the damage to our units and explaining how the components work together to efficiently and safely provide AC to our home. I've never had a technician be so thorough and explain what needed to be done in such a comprehensive and easy to understand way. I really appreciated all his hard work and thoroughness especially on a very hot day!

HVAC Service Call




I highly recommend this company for your HVAC needs! What a tremendous effort by the HVAC Unlimited Team supporting our requirements. I called several other companies who either did not return my call or had excessive emergency rates. The HVAC Unlimited Team was timely, professional, and provided exceptional customer service. The HVAC representative (Jeremy G.) was a total pro -- he kept me informed on his arrival time, provided detailed analysis of the diagnosis, and walked me through the process of bringing my HVAC back to a fully mission capable state. Further, Jeremy was very patient and answered the plethora of questions I had regarding my system and provided information on routine service opportunities that the company can provide. If you are in need of HVAC support, don't hesitate any further, call this team and you will be in good hands.
