Question 1

What to do when my furnace is not turning on?

Accepted Answer

There are a few things you as a homeowner can safely check before you make the call to GSMS.

If your system has one, make sure to check the Emergency Shut-Off switch didn't get flicked by accident. This switch is usually located right next to your heating system or in your staircase walking down to your basement.
Batteries! Check your thermostat has fresh batteries in it… this truly can be a culprit sometimes.
Ensure you have fuel to feed your system.

If those are all verified and you're still having an issue, it's best to reach out to GSMS to perform a complete diagnosis.

Question 2

What type of heating system do I have?

Accepted Answer

Here in New Hampshire, we have many methods of heating our homes and businesses.

First, you either have a gas (propane or natural gas) system or a oil system. This is the type of fuel you purchase to heat.
The second part is you either have a forced air or forced water system. A forced water system, also known as a boiler, uses radiators/baseboards/radiant floor to heat your spaces. A forced air system, also known as a furnace, uses ductwork to blow air into each room.

Our heating specialists are certified & trained to work on all types of heating systems!

Question 3

What is the warranty on the system?

Accepted Answer

New Hampshire homeowners should ask about the warranty on the system and what it covers. A longer warranty can provide peace of mind and protect against unexpected repair costs. At GSMS, we're proud to offer our WOW Warranty where we will match the manufacturer warranty on our labor.

Question 4

What size AC system do I need?

Accepted Answer

It's important to choose the right size system for your home based on factors such as square footage, insulation, and climate. At GSMS, our Project Specialists will perform a load calculation to determine the appropriate size for your home.

Question 5

How long does an AC system last in NH?

Accepted Answer

The lifespan of a central air conditioning system can vary depending on factors such as the quality of the equipment, how well it's maintained, and how frequently it's used. Generally, a well-maintained central air conditioning system can last between 10 to 15 years.

Question 11

What to do when my boiler is not turning on?

Accepted Answer

If your boiler is not turning on, there are several steps you can take to troubleshoot the issue:

Ensure that your boiler is receiving power. Check the circuit breaker and fuse box to make sure there are no tripped breakers or blown fuses. If necessary, reset the breaker or replace the fuse.
Verify that your thermostat is set to the desired temperature and is in the "heat" mode. Sometimes, the thermostat settings may have been accidentally changed.
For older boilers with a pilot light, check if the pilot light is lit. If it is out, you may need to relight it according to the manufacturer's instructions. For newer boilers with electronic ignition systems, ensure that the ignition system is functioning properly.
Check the water pressure gauge on your boiler. If the pressure is too low, your boiler may not operate. Refer to your boiler's manual for the recommended pressure range and instructions on how to add water to the system if needed.
Modern boilers often display error codes when there is a problem. Refer to the boiler's manual to interpret the error code and follow the recommended troubleshooting steps.

If you have tried these steps and your boiler still does not turn on, it is best to contact GSMS.

Question 12

Question 14

What to do if my A/C stops working?

Accepted Answer

If your central air conditioning system stops working, there are a few things you can do to troubleshoot the problem before calling in a HVAC tech. Here are some steps you can take:

Check the thermostat: Make sure the thermostat is set to the right temperature and is working properly. If the thermostat is not working, your AC may not turn on or off at the right times.
Check the air filter: A dirty air filter can restrict airflow and cause your AC to stop working. Check the air filter and replace it if it's dirty.
Check the circuit breaker: If the circuit breaker that controls your AC has tripped, reset it and see if that fixes the problem.
Check the condenser unit: The condenser unit is the outdoor unit that houses the compressor. Check to see if the unit is running and if the fan is spinning. If the unit is not running, check to see if there is power going to the unit.

If these steps do not fix the problem, it's time to call in a AC contractor. Our team can diagnose the issue and make the necessary repairs to get your AC up and running again. It's important to have a Specialist handle any repairs or maintenance on your central air conditioning system to ensure that it's done correctly and safely.

Question 15

When do I need to replace my water heater?
