Common heating and cooling questions answered by our pros in Youngstown

How do I troubleshoot my heating system?

There are a few steps you can take to troubleshoot your system before calling a heating repair pro. To start, make sure the thermostat is set to “heat” and the temperature is above the current room level. Then, check that the circuit breaker hasn’t tripped. For gas systems, confirm that the pilot light is lit. Lastly, inspect the filter—severely clogged filters can restrict airflow. If these steps don’t solve the issue, it may be time to schedule a service call with a professional furnace repair technician.

How long will my furnace repair service take?

Most furnace repair jobs can be completed in a few hours, but of course, every case is unique. If you have a specific furnace repair need, our operators can help you schedule a service call with our pros.

What should I do while waiting for my furnace repair technician?

While waiting for a furnace repair pro, it’s important to first ensure your and your family’s safety. If you suspect a gas leak (rotten egg smell) or your carbon monoxide detector goes off, turn off the furnace and gas (if possible), ventilate your home, and leave immediately. For other issues, simply turning the unit off can do a lot to prevent further damage. If it’s cold out, stay warm with extra blankets or space heaters (used safely) until your heating repair technician arrives.

Why is my AC running but not cooling?

This could be caused by issues like low refrigerant levels, a clogged air filter, or a problem with the condenser or evaporator coil. An AC repair technician can diagnose the issue and restore your system’s cooling performance, ensuring your home stays comfortable.

Can I do my own HVAC installation?

HVAC installation is best handled by a licensed professional as it is a complex process requiring specialized knowledge and delicate safety considerations.

What is involved in an HVAC maintenance service?

Maintenance includes inspecting and cleaning key components, checking refrigerant levels, testing electrical connections, and ensuring proper airflow with thorough air duct cleaning if needed. If any HVAC repair need is detected, it’s addressed on the spot whenever possible.

I couldn’t be happier with Gault. There were no games played. Just a very fair priced, straight to the point estimate for new central a/c and furnace. Installed the following week. Everyone was great. Highly recommend!

They installed a new H/H furnace and A/C unit in my home and it has a noticeable difference already. The old unit was undersized and looked like some 8 year old installed it, the new equipment is first class. But now with properly sized ductwork the home is much more comfortable. You only get what you pay for.

We have our home and an apartment above our detached garage and have had both furnaces replaced in each. Great service. Great installations. Checkups were both great.  Would definitely recommend the company! All employees have been pleasant and helpful.

They did it all in one day and they were efficient. We were told one of the guys was new. There was a small leak in the system, but they came back the same day and fixed it. Their price was very competitive.
