FAQ: HVAC in Campbell, OH

How soon can someone actually come out for an HVAC repair in Campbell?

Our line is answered 24/7, and we run repairs across Campbell and the surrounding valley daily, so most calls get a same-day visit. No-heat and no-cooling calls come first, and members have a same-day guarantee.

I have never used Gault. Why should I now?

We have run heating and cooling in the Mahoning Valley since 1955 and know the older Youngstown-area homes inside out. Most repairs come in under $300 with flat-rate pricing, and every job carries 2-year parts-and-labor coverage. We are also the only Lennox Premier Dealer in Northeast Ohio, and we will tell you when a repair makes more sense than a replacement.

My furnace keeps clicking but will not light. What is going on?

On an older gas furnace, that usually means a dirty flame sensor, a worn ignitor, or a tripped safety switch, not all at once. Leave it off and call us. Repeated cycling on a failing ignition can damage the blower and stress the heat exchanger, and a cracked exchanger leaks carbon monoxide, which is dangerous in any home but especially in one this small and tight.

My AC never stops running but the house stays warm. Why?

A unit that runs nonstop without cooling is usually low on refrigerant, fighting a failing capacitor, or stuck with a bad expansion valve, and frost on the lines confirms airflow or charge is off. It needs a real diagnosis, not a shot of refrigerant that hides the fault for a few weeks.

Is a maintenance plan really worth it?

Usually yes. It covers annual tune-ups, waives after-hours service fees, and takes 15% off repairs for $238 a year, and one part caught early tends to cover the whole plan.

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.

Our HVAC Services

Repair Service in Campbell, Usually Same Day

An aging furnace or AC rarely fails at a convenient time. We answer the phone at any hour, and for members that same-day visit is guaranteed, not hoped for.

Can You Really Get Here Today?

For members, yes, guaranteed. Everyone else, we always do our best, but we'll give you a straight answer if the schedule is full.

We diagnose and price the repair before any talk of replacement, since a targeted fix is often all these homes need. Members also get a repair discount and a longer labor warranty.

Do You Work on My Kind of System?

We repair central AC, heat pumps, and gas furnaces, plus the boilers and old gravity systems still hiding in Campbell basements. For homes that were never ducted, a mini-split is usually the smartest path, and we handle those start to finish.

  • Central AC
  • Ductless Mini-Splits
  • Heat Pumps
  • Furnaces (Gas, Propane, Oil)
  • Boilers

Do You Service My Brand?

Installed by us or not, our EPA 608-certified techs work on any brand: Lennox, Carrier, Trane, Goodman, Rheem, Bryant, York, and more.

We are also equipped for the new R-454B (A2L) refrigerant, so a system from this year and a furnace from the nineties both get handled right.

HVAC Maintenance (Included with Membership)

Benefits of Routine HVAC Maintenance

When you're working with an older HVAC system, a yearly tune-up buys you more safe seasons and flags a cracked heat exchanger before it becomes a safety problem.

Members get annual furnace and AC tune-ups, waived service calls, no overtime charges, 15% off repairs, and priority scheduling. Plans start at $238 a year.

HVAC Maintenance and Warranties

Most manufacturer warranties require documented yearly maintenance, and skipping it can void your coverage right when a major part fails.

We keep that record current, backed by our own 2-year repair and 10-year install warranties.

Precision HVAC Installations, No Guesswork

Some pros doing HVAC replacements in Campbell will start by matching the nameplate on the old unit, and that is the absolute wrong approach when the house has been remodeled twice since that unit went in.

At Gault, we run a Manual J load calculation and inspect the existing ductwork before we quote anything, so you get a system that actually fits your home, not one that relies on an assessment made 100 years ago.

And as with every installation we perform, you always get 10 years of parts-and-labor warranty coverage and a full year of maintenance included.

Our 10-Year Warranty Covers What The Manufacturer Doesn't

Read the fine print on a factory warranty and you will find it covers the component but charges you for a tech to put it in. Seven years in, that "free" control board still costs a couple hundred to install.

At Gault, our HVAC installation warranty closes that gap with full parts-and-labor coverage for 10 years, so there is no bill on a covered repair, period.

The Region's Only Lennox Premier Dealer

Lennox holds its Premier Dealers to a higher install and service standard than a typical contractor, and re-certifies it annually on training hours and customer scores. And we are the only shop in Northeast Ohio with this coveted designation.

For you, that translates to a properly commissioned system, access to Lennox's full warranty program, and Lennox-specific parts on our truck instead of on back order.

Duct Cleaning for Regular Service or Years of Build Up

When A Duct Cleaning Is Worth Paying For

Much of the ductwork in Campbell was run decades ago. If you just bought a place, pulled up old carpet, or tore out a wall, that debris is sitting in the trunk line and blowing back every time the blower kicks on. That is when a cleaning makes a real difference.

We will be happy to help you with annual cleanings, but we never push them. If we put a camera in and the ducts look fine, we close them up and you do not pay for work you did not need.

Members Pay Less & Book First

Duct cleaning is discounted under the maintenance plan, with no added trip charge and priority booking.

Cleaner Air, Even For Homes That Weren't Built For It

Whole-Home Purification for Old, Tight Construction

Historic homes in Campbell were built small, close together, and low to the ground. Ventilation was not part of the design, and once winter shuts the windows, dust, cooking smoke, and whatever the old walls are holding get trapped.

A purifier mounted in the supply plenum filters every cubic foot the system moves, which is a different job than a plug-in running in one corner of the living room.

Finally Stop Fighting Basement Moisture With a Whole-Home Dehumidifier

If you are dropping the AC to 70 and the house still feels clammy, the problem is humidity, not temperature. A whole-home dehumidifier strips the moisture at the source, so the air feels comfortable without overrunning the compressor. In a block-basement home it also dries out the lower level where standing dampness and mildew tend to set in every summer.

On the flip side, forced-air heat dries the house out by February, and a whole-home humidifier fixes that without the maintenance headaches of a portable. We also mount UV germicidal lamps at the coil to stop biological growth at the source.

Water Heater Replacement That Fits the House and the Budget

Standard Tanks: Reliable, Affordable, Easy to Maintain

On Campbell's municipal water, a conventional tank is low-maintenance and long-lasting when it is sized right. The most common issue we see is a tank that is the wrong size for the household, either burning gas all day on water nobody uses, or leaving the last person in line with a cold shower.

We size your new water heater to your actual demand. If your current tank is failing, we give you a straight answer on whether a repair is worth it or you are better off replacing now.

Going Tankless: What It Takes in a Smaller, Older Home

A tankless unit delivers endless hot water and cuts the gas bill, but in a tight Campbell basement the install is not always plug-and-play. The gas line may need upsizing, the venting may need rerouting, and the upfront cost is higher.

We walk through all of that before you sign anything, because knowing the full scope up front matters more than a low quote that grows once the work starts.
