Commercial HVAC Services in Lathrop

When it comes to commercial HVAC repair services, it’s always best to hire an expert. Not only is a commercial HVAC system larger than a residential system, it is also spread across the property. A commercial system needs proper ventilation and exhaust systems in place to ensure that the building’s air quality isn’t affected. On top of this, the exhaust system of your commercial air conditioner needs to meet local, state, and federal specifications. All in all, the complexity involved in installing, repairing, or replacing a commercial air conditioning system requires a trained technician.

Fortunately for local business and commercial property owners across the Central Valley, Irish Heating and Air technicians have the expertise and equipment to successfully complete your commercial HVAC project efficiently and effectively. Our technicians are local to the area, so whether your property is located in Lathrop, Lodi, Modesto, or any other city in the Central Valley, schedule an appointment with us today, and we’ll get your commercial HVAC system back up and running in no time.

“These are honest people.  This alone is enough for me to hire them but given the fact that they did a superb job of putting two 4 tons on my home in 2 days and leaving a clean attic tops the scale.  Ryan is a man of his word.  In addition to that, it shows he cares more on the job being done than its monetary gains.   Jesus and Martin are like boy scouts! They never failed to impress me.  Not only did I feel they never took their jobs for granted but they made sure everything is working and in perfect condition before leaving.   If you are looking for an HVAC company, look no further.  7 companies came to my house before them.  Although the price they quoted are competitive,  Its their work ethics that left the others in the dust.”

Furnace Repair & Installation Services

While reliable air conditioning is a little more crucial than heating in Lathrop, it’s still not a lot of fun to shiver through Christmas.

The good news is that our heating contractors are experienced with every major brand of heating equipment that you’ll find in Lathrop, which means you’ll enjoy fast, dependable repairs on equipment by:

Our first priority is always to try and repair your current equipment. After all, there’s no sense in shelling out for a new furnace when you can get a few more years out of your current one. Our team regularly replaces cracked heat exchangers, broken blower components, and gas leaks, and we can perform most furnace repairs in only an hour or two.

Even the best furnace isn’t made to last forever, though. If your furnace is 8-12 years old, chances are good that it’s nearing the end of its lifespan. That means you can fix one thing only for two more to break. When that time comes, our affordable financing options make it easy to buy a new furnace that will keep your family warm and toasty for years to come. Call now to learn more.

There are many reasons your furnace could lose connection to your thermostat, including bad wiring, faulty power source, other settings overriding your manual settings, and problems with the furnace itself. An improperly installed smart thermostat can even break your furnace.

First, don’t panic.

All furnaces have a reset button somewhere on the unit. Typically they’re red or yellow and located inside the blower compartment. See if the button has been tripped and push it if necessary.

Next, make sure your thermostat is set correctly. Most automatic and smart thermostats have a manual heating mode you can switch on, which will override any other commands. 

Finally, check the breaker panel. If there is no sign of power for your furnace, there’s a chance it could have tripped the breaker.

If you’ve checked all of those options and your furnace still isn’t turning on, it’s time to call in a technician. There are many other things that can go wrong with a furnace, but there are only so many fixes that you can DIY. 


Furnaces use the flue, or vertical exhaust, to eject carbon monoxide and other compounds. Many of these compounds can be toxic or harmful if inhaled, so a clear flue is a necessity.

If you see excessive soot around the flue, water streaking down the walls of your furnace, or a yellow pilot light, chances are good that your flue is clogged. Be sure to call for help at the first sign of trouble.
