Heating Service & Repair


Signs Your Heater Is Malfunctioning​


Because of how much use your heating unit gets during the cold months, it experiences wear and tear and eventually may require repairs. However, before you experience complete system failure, it's important that you're aware of the signs your system needs repairs so we can fix them before they evolve into more serious and costly problems.



Common symptoms of a malfunctioning heater include:
  • It doesn't emit enough warmth
  • It cycles on and off too often
  • It provides uneven heating throughout your home
  • It will not turn on or shut off
  • It makes unusual or loud noises
  • You need to frequently adjust the thermostat
  • You smell burning
  • Your energy bills are unusually high
It's extremely important that you don't ignore any of these symptoms. The sooner you call our New Jersey heating repair experts, the quicker we can diagnose the issue and perform the necessary repairs.





Let the Professionals Handle It​


Even if you have a small issue or part in need of repair, it's important that you let a professional take care of it for you. An improper repair could pose a threat to your safety and it may not meet local building codes. It could also end up doing further damage to other parts, which makes additional repairs even more costly and extensive.

At Guaranteed Service, your comfort and ease are our priority. We are highly knowledgeable of the best and most efficient ways to inspect and fix heating units and we guarantee that we will get the repair done correctly.

Already Recommended to Neighbors
Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too. We were very pleased, especially right now when people are having so many problems getting supplies and equipment. Already recommended to neighbors.

Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job.
