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.

FAQ: Indoor air quality in Grove City, PA

How do I know if I have a problem with indoor air quality?

Common signs include persistent allergy or asthma symptoms, musty or stale odors, excessive dust buildup, and air that feels unusually dry or humid. If symptoms improve when you leave the house and return when you come back, poor indoor air quality is likely a factor. Our team can assess your home and recommend the right solution.

What is the difference between an air purifier and a UV light system?

Air purifiers use filters to physically capture airborne particles like dust, pollen, pet dander, and mold spores. UV light systems use germicidal ultraviolet light to neutralize bacteria, viruses, and mold that pass through your HVAC equipment. Both systems work well together, and our team can help you decide what makes sense for your home.

Do I need a whole house humidifier, or will a portable one work?

Portable humidifiers treat one room and require constant refilling and cleaning. A whole house humidifier integrates directly into your HVAC system and automatically maintains consistent humidity levels throughout your entire home. For Grove City homeowners dealing with dry winter air, it is a far more practical long-term solution.

What humidity level should my home be at?

The EPA recommends keeping indoor humidity between 30% and 50%. Air that is too dry causes irritated sinuses, static electricity, and damage to wood floors and furniture. Air that is too humid promotes mold, dust mites, and structural damage. Our whole house humidity control systems keep your home in the right range automatically.

How often do I need air filtration maintenance?

Most whole house air purifiers need filter replacement every 6 to 12 months depending on usage. Regular air filtration maintenance also includes checking components and confirming the system is properly integrated with your HVAC equipment. Our technicians can handle all air purifier maintenance and repair on a schedule that works for you.

Can a dehumidifier help with mold in my basement?

Yes. Excess humidity is the primary driver of mold and mildew growth in basements and crawl spaces. A whole house dehumidifier installation addresses the source of the problem by continuously removing excess moisture before it causes damage. If you have noticed musty smells, condensation on walls, or visible mold, give our Grove City team a call.

Indoor air quality in Grove City, PA

Indoor air can carry two to five times more pollutants than outdoor air. Dust, allergens, mold spores, bacteria, and humidity imbalances affect your family's comfort and health every day. Gault Heating & Cooling offers complete service for indoor air quality in Grove City, PA, including air purifier installation and repair, HVAC UV light installation, whole house humidifier installation and maintenance, and whole house dehumidifier installation. We assess your home, recommend what will actually make a difference, and integrate everything with your existing HVAC system so it works automatically.

And at Gault, every indoor air quality job is backed by our 2-year warranty. Our technicians are background-checked, certified, and honest about what your home needs. We have served Grove City families since 1955 and that is not a claim we take lightly.

Air purifier installation, repair, and maintenance in Grove City, PA

Whole house air purifiers integrate directly into your HVAC system and filter every cubic foot of air that passes through your home. They capture dust, pollen, pet dander, mold spores, smoke particles, and chemical off-gassing from household products automatically, without any daily attention from you.

Air purifier installation

We size and install air purification systems based on your home's square footage, existing HVAC setup, and your specific air quality concerns. Our air purifier installation process includes a full walkthrough of what to expect and how to keep your system performing well over time.

Air purifier repair

If your air purifier has stopped working or is not performing the way it used to, our Grove City technicians can diagnose and fix the problem quickly. We service all major brands and carry common parts on our trucks, so most air purifier repair jobs are completed in a single visit.

Air filtration maintenance

Clogged or degraded filters do not just stop working. They restrict airflow and add strain to your HVAC system. Our air filtration maintenance service includes scheduled filter changes, component inspections, and system checks so your air purifier stays effective year-round.

HVAC UV light installation in Grove City, PA

Standard filters capture particles but cannot neutralize living biological contaminants. HVAC UV light installation adds germicidal UV-C light inside your HVAC equipment, destroying bacteria, viruses, and mold spores as they move through your system. UV lights are especially effective at eliminating mold growth on evaporator coils, which is a common source of musty odors and airborne spores.

UV light systems are low-maintenance and operate continuously in the background. Most bulbs last one to two years and can be added to virtually any existing forced-air system. Our Grove City team will identify the right placement for maximum effectiveness and complete the installation cleanly.

Whole house humidity control in Grove City, PA

Grove City homes deal with humidity on both ends. Winters bring dry air that irritates airways, damages wood floors and furniture, and increases static electricity. Summer brings heavy humidity that makes your home feel hotter, promotes mold growth, and causes musty odors. Our whole house humidity control systems automatically maintain the ideal 30 to 50 percent range year-round.

Whole house humidifier installation and repair 

A whole house humidifier integrates with your HVAC system and maintains consistent humidity throughout your entire home without any manual effort. Gault handles whole house humidifier installation for flow-through, drum, and steam systems, and we match the right unit to your home's size and heating setup. We also provide whole house humidifier maintenance to keep the system running reliably, and humidifier repair when something goes wrong.

Whole house dehumidifier installation and repair in Grove City, PA

Excess moisture creates the conditions mold, mildew, and dust mites need to grow. It also warps wood floors and worsens allergy and asthma symptoms. A whole house dehumidifier works with your HVAC system to continuously pull excess moisture from your home's air supply, automatically maintaining a healthy humidity level without portable units that fill up and require constant attention.

Our Grove City team handles whole house dehumidifier installation from start to finish, including proper sizing, HVAC integration, and drainage setup. If your existing unit is struggling, our dehumidifier repair service will get it sorted quickly.
