Frequently Asked Questions

What should I do before calling for service?

There are a few things you can do to help us help you…

  • Make sure the thermostat is functional and is calling for heating or cooling
  • Make sure that the air filter is not plugged
  • Check to see if a circuit breaker is tripped or off (breakers are usually tripped if the switch is in the middle between on & off)
  • Notice if there are/were any unusual sounds or smells coming from the equipment
  • Most modern furnaces have a diagnostic LED light that can be seen through a peep window on the front panel.Look for that light – error codes are a series of blinks followed by a pause (some Carrier furnaces error codes are a series of rapid blinks & a series of slow blinks followed by a pause). If this code can be noted before resetting the furnace it is a huge help in troubleshooting. These can help save time ($).

How do I reset my furnace?

If your furnace fails, first check to see if an error code is present (see bullet point above) and note it. Most furnaces can be reset by turning the thermostat to “off”, and then turning the heat back on. (Because most furnaces have a door switch that shuts the power off on the front panel, be sure to note any error code before taking any panels off.)

Should I repair or replace my heating & cooling equipment?

This is a question many people start asking when their equipment reaches 10+ years old…and there isn’t a simple answer. Most repairs are fairly cheap compared to buying new equipment, but those repairs can add up fast. If a major repair is needed, it may be more cost effective to buy new equipment (with a new warranty & higher efficiency) than to keep making more and more repairs. Maintenance is also a factor…the life span of heating and cooling equipment can definitely be extended by having the correct duct work, air filtration and installation, along with regular maintenance work.

How should I choose a Heating and Cooling contractor?

There are many companies out there to choose from. Some are very cheap (but may cut corners to maximize profits), while others might charge a premium for the top of the line services…and then you have everything in between. The most important thing to think about is that the quality of the work will affect the lifespan of your equipment, as well as the performance and efficiency of your heating and cooling systems. In fact, the quality of your contractor will usually affect your satisfaction more than the brand of equipment you choose! Going with the lowest bid usually costs more down the road due to these issues. Always choose a contractor that is licensed and insured, and don’t be afraid to ask if their training and credentials are up to date. Choosing a contractor with a history of quality workmanship, attention to detail, and a reputation for taking care of customers (at a fair price) is usually going to lead to increased happiness with your system, and the least amount of future headaches.

How often should I change my air filter?

This depends on how efficient your air filter is, how much run-time the furnace fan or air conditioning system has, as well as the environment you’re conditioning (e.g. how many people and how many pets live in the space). A good rule of thumb is to check your air filter every month, and we recommend changing filters every 3-6 months, depending on the type of unit. The more efficient your filter is, the quicker it will plug up. Take a new filter and hold it up to a bright light you’ll notice plenty of light shines through, a plugged filter will have no light shining through. The optimal time to change the filter is half way between these two.

What should I think about when I am planning to have a new heating and/or air conditioning system installed?

There are many different types of heating and cooling systems available, so doing some homework will help with this decision. In addition to your budget for a project, you should think about how efficient and quiet you want your HVAC system to be, as well as the level of air filtration and indoor air quality you want. You should also consider what type of control of your heating and cooling system you would prefer…ranging from a simple thermostat to full automation with all the bells and whistles. Morrison Heating & Cooling can assist with more information when you are developing your plan.

Is the size of heating and cooling important?

Frequently Asked Questions

Yes, sizing is one of the most important aspects of a good system. A quality heating and cooling contractor will do what is called a load calculation for your home or business. A load calculation algorithm takes many things into account to figure out exactly how much system capacity is needed to keep your space comfortable, without wasting energy.

Will I ever need to check my duct work?

Yes! Leaky duct work causes more than 20% of energy losses in heating and cooling (according to the U.S. department of Energy). Old duct work can break apart and duct sealing can fail. The best duct systems are supported, sealed and insulated to code or above. Insulation can also fall apart or older insulation may not be as thick as current codes and recommendations. We can check out your duct work to be sure that it’s not costing you money.
