When your AC stops pulling its weight

Not sure what’s going on with your air conditioning? We’ll help you diagnose the issue. If it’s worth fixing, we’ll repair it. If not, we’ll help you choose a solid replacement and take care of the installation permits and warranty paperwork.

Every new install comes with free scheduled maintenance to keep it running strong.

Did you know that roughly 85% of HVAC breakdowns are totally avoidable with routine maintenance? 

Bringing the heat without the headache

Heating is about more than comfort. It’s about your safety, your life. If your heat goes out in the thick of winter, you’ll feel it fast.

Our pros have been working in this region since 1955. We know from personal experience just how important it is to have home heating you can count on. We do it all, including repairs, replacements, installations, and maintenance.

 If you’re considering an upgrade, we’ll help you choose a high-efficiency system that keeps your home warm while cutting down on energy use. Better for your bills, and better for the environment. Plus, every new installation comes with a 10-year warranty and free maintenance service.

Hot water trouble? We got you

They say cold showers are good for your health. Even if you believe them, you still want to have the choice.

We can help with replacements and installations for every type of water heater, including tank and tankless, gas and electric.

Cleaner air, clearer head

The air you breathe in your home is only as good as the ducts and equipment moving it. If things smell stale, feel stuffy, or kick up your allergies, especially if it’s been more than 3-5 years since your ducts were last serviced, it might be time for a deeper look and a deep cleaning.

We offer duct cleaning, repair, and replacement, plus smart indoor air quality services like UV lights, purifiers, humidifiers, and dehumidifiers.

Transparent pricing with no fine print

When it comes to pricing, we like to keep things simple and direct. Never any games, surprise markups, or pressure.

Here’s how we work:

  • $85 service call fee
  • No overtime charges
  • No markup on parts
  • Upfront estimate before we begin
  • Multi-year warranties: 2 on repairs, 10 on installations

Direct answers, no runaround

Do you charge a service call fee for HVAC requests?

Yes, there is a flat $85 fee for all HVAC service calls. We never charge for overtime, and we never mark up the cost of parts.

What kind of warranties do you offer?

We stand behind our work with 2 years of coverage on all repairs and a full 10 on all new heating and AC installations.

How often should I have my HVAC system serviced?

We recommend two tune-ups a year, one before heating season and one before it’s time to fire up your AC. Regular maintenance keeps your HVAC systems efficient, helps them last longer, and cuts down on surprise repairs.

Why do you recommend annual maintenance for my new AC unit?

It’s important that your AC stays fit to handle the hot, sticky summers here in Shenango. Roughly 85% of breakdowns are avoidable with regular maintenance and fast repairs. If you don’t get your new AC serviced annually, you might need to replace it sooner, which is costly.

When should I consider getting air duct cleaning?

If you notice extra dust, musty smells, or inconsistent airflow, or if it’s been more than 3 to 5 years, you’re probably due for service. Clean ducts improve the quality of the air you breathe in your home and contribute to a more efficiently performing HVAC system overall.

What types of indoor air quality services do you offer?

We install UV lights, air purifiers, humidifiers, and dehumidifiers to help improve the air you breathe and support your HVAC system. We offer duct cleaning for heating and air conditioning efficiency as well.

Is it better to repair or replace an older heating or AC unit?

If your system is over 15 years old or needs constant repairs, replacement is usually more cost-effective. We’ll give you honest advice based on your home and budget.

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.

Gault does our gas furnace tune up every year. They’re friendly and easy to schedule service with and the technicians are always polite and helpful. Great company to deal with.
