Rising energy bills, cold spots and unusual odors can all point to heater trouble. Learn these three warning signs and when to call an HVAC professional.

As you use your heating system more heavily through the colder months, it helps to stay alert to how it is running. Catching problems early with timely heater repairs can save you money on more extensive repairs and help you avoid a breakdown during the coldest part of the year.
Consider scheduling service with a qualified HVAC technician if you notice any of these three warning signs:
One of the most useful heater repair tips is to pay attention to your monthly utility costs. Unless you add a major appliance or change your heating habits, your energy usage should stay fairly steady from one similar month to the next.
If you see an unexplained rise in your utility costs, a heating and cooling technician can help. Even if your heater is not the cause, an inspection helps you rule out a heating malfunction.
Temperatures may vary slightly from room to room, but your indoor climate should still feel fairly consistent. If one room feels noticeably colder than the room next to it, your system may be having trouble keeping up, or airflow may not be reaching that space properly.
A technician can determine what is causing large temperature differences in parts of your home, whether it is the equipment itself or the ductwork and airflow.
It is a good idea to check on the heating unit in your basement or crawl space from time to time.
These checks can help you notice unusual odors, such as the smell of rotten eggs. That smell can indicate a natural gas leak. If you smell gas, leave the home and call your gas utility right away from outside.
It is also wise to install a carbon monoxide detector near your heater and on each level of your home. A carbon monoxide problem often traces back to a cracked or damaged heat exchanger, so have the furnace inspected promptly if a detector alerts or you suspect a problem.
When you notice any of these signs, schedule service with a licensed HVAC professional. A good technician can repair your system and give you practical guidance on keeping it running well.
