Troubleshooting

If you’ve scheduled an appointment with High Mark Heating & Cooling to come to your home to discuss new products or service your existing system, you’ve made a great choice. We are known for great service and a reputation for doing Whatever It Takes® to keep you and your family comfortable. Here’s what to expect during your appointment:

We will arrive at your home at the scheduled time of your appointment.  If our representative will be late, he or she will call you in advance to let you know or to reschedule.

• When we get to your home, he or she will likely want to inspect your existing system to understand the unique details and situation of your home. In doing so, we may request access to all areas of your home—from rooms to crawl spaces, attics, etc.

• We might ask you several questions about your existing system. You may want to prepare in advance for these questions.

• You will also likely be asked questions about your family’s special heating, cooling and air quality goals and needs.

• Once the meeting has ended, if a follow-up meeting is needed for further discussions or service, you can expect our friendly staff to get back in touch with you right away.

IT TAKES Being Informed

Take a moment to make sure you’re prepared for our visit. Following this simple checklist before your appointment will help us get straight to servicing your system.

• Know where all of the heating and cooling units are in your home.

• Check your air filter. A dirty air filter is a common cause of problems.

• Write down the model and serial number of all your HVAC products.

• Be ready to explain clearly what problems you’ve had.

• Know when your problems began.

• Make sure the system is accessible by the dealer, including units in crawl spaces or attics.

• Put pets in a separate room.

• Make sure an adult (18 years or older) is home to let your dealer in.

• Be prepared to answer the phone. Many technicians call when they’re on the way.

• If you rent, make sure you have permission to have your system serviced.

• If your heat pump is frozen, shut it off before the technician arrives so it’s thawed and ready for service.

• Have information on all prior services performed on your system readily available.

• Be prepared to make a payment at the end of your service appointment.

IT TAKES Trying Simple Things Before Calling

You can always count on High Mark Heating & Cooling for help and service. But here are a few simple things you might try before scheduling us to visit your home:

Air Conditioning Equipment Checklist

1. Check to make sure that your thermostat is set in the “cool” position.

2. Ensure that your outdoor air conditioning (condensing unit) is running.

• Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to an outside wall in the back of the house. Make sure they are all in the “ON” position.

• Check the outdoor unit “disconnect switch” to make sure it is in the “ON” position. The disconnect switch is located near the outdoor unit. (Normally a grey 8″ wide x 16″ high x 4″ deep box mounted to the wall).

3. Ensure that the blower motor in your furnace is running. (If the thermostat is in the “cool” position, the furnace blower should be running.)

• If not, check to make sure the on/off switch at the furnace is in the “ON” position.

4. Be sure that you have changed your filter in the furnace recently.

• An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow.

5. Check all return air grilles to make sure they are not blocked by furniture.

• Furniture should be moved at least four inches away from return air grilles to allow for adequate air supply.

Gas Furnace Equipment Checklist

1. Check to make sure that your thermostat is set in the “heat” position.

2. Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat.

3. Ensure that there is power to the furnace.

• Try turning the fan to “ON” using the fan switch on the thermostat to test for power to furnace.

4. Check the circuit breakers at the electrical panel.

5. Check the SSU switch (it looks like a light switch on a gray box located at the furnace) to be sure it is in the “ON” position.

6. Check to ensure the furnace filter isn’t in need of replacement.

• All one-inch thick furnace filters should be replaced monthly.

• Wider two-inch thick and other high-capacity pleated filters can most likely be changed every other month or just six times per year.

7. If the system is running but you have not changed your filter, the filter needs to be replaced.

8. Check all return air grilles to make sure they are not blocked by furniture.

• Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).

If these checklists do not solve your problem, contact High Mark Heating & Cooling right away for service. Be sure to have your model number.

Knowing the model number of your HVAC products will help you troubleshoot any problems and will make it easier for us to provide service.

In addition to being listed in your owner’s manual or other paperwork that came with your HVAC system, the model number is also posted directly on your unit. Here’s how you find it:

• Air Conditioners and Heat Pumps: You can find the model number listed on a “rating plate” sticker on the unit above the back-seated service valve connections.

• Gas or Oil Furnaces: Remove the front door and look at the upper-left side of the unit. You can find the model number listed on a “rating plate” sticker inside of the unit.

If you have a non-Bryant product, look for a “rating plate” sticker on the unit. And of course, if you are unable to find your model number, you can always call High Mark Heating & Cooling.
