A Quick Inspection Can Save You from Bigger Problems
When your heating or cooling isn’t keeping up, it can be frustrating, and you might start worrying about the cost of a full replacement. But many times, the problem is something much smaller, like a dirty sensor, a minor leak, or a simple calibration issue. Left unchecked, though, those small problems can grow into expensive breakdowns at the worst possible time.
Let’s say you’re in Worden and your AC keeps cycling every few minutes. Our team runs a thorough inspection, pinpoints a faulty control board, and fixes it on the spot without the pressure or unnecessary upsells. Just honest repairs that get your system back to work.
What We Check During an HVAC Diagnostic Visit


Our heating and cooling evaluation is designed to give you answers, not guesses. We take time to check all the key areas that affect system performance and safety.
Here’s what’s included:
- Airflow and temperature readings
- Filter condition and placement
- Electrical component testing
- Thermostat calibration
- Refrigerant pressure and charge
- Motor and fan operation
- Safety switch and ignition system checks
- Ductwork flow and air quality concerns
We finish by explaining what we found and what your options are, with no pushy sales tactics or confusing terms.

HVAC Troubleshooting for Any System
Heating or cooling issues can happen with any brand, and finding the root cause takes more than guesswork. Our technicians have the training, tools, and experience to quickly diagnose problems and get your system running right again.
We perform HVAC troubleshooting for all major brands and systems, including:
- Central air conditioners
- Heat pumps
- Furnaces
- Ductless mini splits
- Thermostats and smart systems
- Hybrid heating and cooling setups
If your system works sometimes but not consistently, or if energy bills are climbing without reason, it’s time to schedule a diagnostic.

Why Homeowners Trust Our Inspection Process
We don’t show up with a checklist and guess what’s wrong. We use real tools, training, and experience to inspect your system properly. Our job is to give you clarity so you can make an informed choice.
What you can expect:
- Certified HVAC techs with real field experience
- Clear, upfront pricing
- No unnecessary recommendations
- Flexible scheduling
- Veteran discounts
- Financing available if repairs are needed
Our goal is to solve the issue, not sell you something you don’t need.

What Customers Say About Our Diagnostic Service
Sent a message to Platinum on Sunday to fix our AC. The next morning, they called back and said they could have a technician at my house in a matter of minutes. Not even five minutes later, our guy shows up. Did some extensive testing and troubleshooting. Recharged the system and had it up and running in about an hour. Now it works better than ever. And the cost was very reasonable. Jacob (the technician) did a great job. He’s very professional and he really knows AC systems. Platinum is our first choice for HVAC repair. We’re always happy to support local businesses. Thanks

Customer
Customer service: Amazing. Communication: Amazing. Diagnosis of work: Amazing. Cost: More reasonable than others. Customer satisfaction: 5 stars. Our church experienced an AC unit that malfunctioned during one of the hottest heat waves of the Summer. A company came in and misdiagnosed the issue, giving us an astronomical repair estimate. We called around to get another opinion. Everyone we called was at least two weeks out. Several recommended Platinum. Angelo (the owner) and Orlando (the assistant?) came out the next day. They quickly identified an issue and explained the process of repairing it simply.

Customer
Last January my furnace stopped working during the middle of winter during that cold snap when it was -20 degrees. I called Angelo and he came over in the middle of the night to fix the issue. This January the same thing happened and again, Angelo and his team came over and fixed it. Every time I need something to do with hvac I call Angelo and he is on it right away. It’s always a great experience and always a great price!

Customer
Amazing company is putting it lightly… everything from the estimate to the final product being installed everything was easy, affordable, and the work is second to none scheduling and communication with the owners was amazing. very helpful and knowledgeable about the products they service. Can’t recommend this company enough

Customer
