Preventantive Maintenance For HVAC Systems Griffin Mechanical, LLC understands that when it comes to something as important as your home’s heating and cooling system, peace of mind is essential. Our maintenance plans ensure that your heating and air system is running in optimal condition all year round. On each maintenance tune-up, our technicians review the entire system for maximum functionality. We check electrical readings for the proper range, refrigerant levels for the correct amount, and components (such as belts, pulleys, motors and fans) for signs of wear or evidence of possible damage. Spring HVAC Maintenance In addition to the services listed above, our Spring maintenance visit also includes coil cleaning, which allows air to pass over the coils and helps the system ‘breathe’ properly. Fall HVAC Maintenance Like our Spring maintenance visit, our Fall maintenance visit also includes season appropriate checks. We look for evidence of carbon monoxide leakage, which can harm people and pets (and can lead to death if undetected). We can also look at a homeowner’s water heater at no extra charge.
