Common questions answered by our AC and heating service experts in Warren

From heating installation to AC repair and air duct cleaning, Ohio’s top-rated HVAC service professionals are here to answer any question you might have.

How long does AC repair take?

Most AC repair jobs are handled within a few hours, although more complex issues may take longer. Variables such as system access and part availability can impact the total time.

How often do I need an HVAC replacement?

Every 10 to 15 years is the most common range for HVAC replacement, though it really depends on maintenance and overall usage.

How often is HVAC maintenance necessary?

Scheduling HVAC maintenance twice a year is recommended to keep your Warren home’s system running efficiently.

When is the best time for heating maintenance?

The start of fall is ideal for scheduling heating maintenance so your system is prepared for the colder months ahead.

What should I consider for a new heating installation?

Efficiency, size, and fuel type are key factors for heating installation, as they impact energy costs and comfort.

How can I troubleshoot my home heating system?

Check the thermostat, filters, and circuit breakers to address common issues. Ensure power is on and filters are clear, as clogs can reduce system performance. For more persistent issues, it’s best to consult a heating repair professional.

How frequently should I get air duct cleaning?

Every 3 to 5 years is generally sufficient, though homes with pets or residents with allergies may benefit from more frequent service.

Customer Reviews

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.
