There are several recurring patterns we encounter when it comes to heating repair issues:


Can prevent a call for heat from reaching your heating system, or hamper your heating unit’s ability to function when everyone in your house knows it should be.


Are very common and most often due to failing or faulty belts, bearing, or fan motors. This can very quickly result in overheating and cause your heating system to under perform, start and stop erratically, or even cease functioning altogether.


Due to lack of regular maintenance. For more information on preventing preventable issues from shortening your furnace’s lifespan, see our maintenance section, where we explain how One Hour Heating and Air Conditioning can work with you to get the most out of all your equipment.


Another recurring issue is dirty or clogged filters that restrict airflow and eventually lead to serious problems. This is much more common in households with pets, where stricter attention to filter replacement is required.


Malfunctions are as common as they are unpredictable. Luckily, they are very manageable fixes.

Q: What is a heat pump?

A: A heat pump is a dual purpose heating and cooling system. Rather than having two separate systems, such as a furnace and an air conditioner, a heat pump can keep your home cool during the summer and warm during the winter.

Q: Why is my furnace blowing out cold air when the heat is on?

A: When experiencing this problem, your first step should be changing the air filter and see if your furnace starts blowing warm air. DO NOT ignore this issue. Long term overuse will hurt your furnace heat exchanger, which is an expensive fix. Another possible option if you have a gas furnace is checking the pilot light to make sure it did not go out.

Q: What should I do if my furnace will not come on?


  • Check your fuse box and make sure that your breaker is not flipped. If the breaker has been tripped, then no power will go to your system. Once you have switched it back on, check that there is power going to your thermostat, air handle, and outdoor HVAC unit. If you notice your breakers tripping regularly, then you may need to contact a qualified electrician.
  • Check to see if your air filter needs to be replaced. When is the last time you examined your air filter? It can quickly accumulate dirt and particles (especially if you have pets) that make your machine work harder than it is designed, which can lead to system malfunction. Make note of the size (typically height x width in inches) when you order replacement filters. It’s often a good idea to have a set of back up filters on hand.  
  • Check your thermostat. First, ensure it is on the right setting. Is it set to “fan” by mistake? Second, check the location of your thermostat. Is there a heat source that could be affecting the reading? Is it located near a fan? If so, the your thermostat might be reading the temperature incorrectly. Investing in a Smart-thermostat is a great option, this will allow you to check & adjust your settings remotely.  
  • When in doubt – call a professional service tech.  One Hour Heating & Air’s qualified HVAC specialists are on call 24 hours a day to ensure that your system is operating at its best. Call now to schedule an appointment.

Q: How often do I need to replace my furnace?

A: Furnaces typically have an average lifespan of 12-15 years, depending on if it was professionally maintained.
