Benefits of Regular HVAC Maintenance
Taking care of your HVAC system isn’t just about checking a box—it’s about saving money, avoiding breakdowns, and keeping your home comfortable all year.
Here’s what regular maintenance can help you do:
- Prevent Surprise Breakdowns: Small issues get caught early, before they turn into expensive repairs or full system failures.
- Lower Your Energy Bills: A well-maintained system doesn’t have to work as hard, which means it runs more efficiently and costs less to operate.
- Extend the Life of Your Equipment: Routine maintenance reduces wear and tear, helping your HVAC system perform better for more years.
- Protect Your Warranty: Many manufacturer and labor warranties require annual service to stay valid—miss it, and you could be stuck footing a big bill.
We recommend annual maintenance for most systems—twice a year if you use the same one for heating and cooling.

HVAC Maintenance Services to Keep Your Heating and Cooling Systems Running Right
Your HVAC system needs regular tune-ups to stay efficient, safe, and reliable. Some upkeep—like changing air filters—is simple enough to do yourself. But most of it? That’s what our licensed technicians are here for.
Here’s what we cover during a professional HVAC tune-up, and what you can do in between visits to keep things running smoothly.
When we perform an AC maintenance visit, we start by cleaning the outdoor condenser coils so your system can breathe and run efficiently. We also check refrigerant levels and pressure to make sure your home’s actually getting cool, not just blowing air. Our technicians inspect electrical components, tighten connections, and test your thermostat to ensure the entire system communicates the way it should. We’ll also check indoor airflow and inspect your evaporator coil for buildup that could cause future issues. Every detail gets covered so you’re not caught off guard on the next hot day.
Mini splits need a little extra attention, especially if you’ve got multiple zones running year-round. During your mini split maintenance, we clean the indoor units, including filters, coils, and blower wheels, to keep airflow strong and your system quiet. Outside, we check the condenser for dirt, leaves, or anything that could restrict performance. Refrigerant pressure is tested and adjusted as needed. We also make sure each indoor head is communicating properly with the remote and outdoor unit.
Because heat pumps heat and cool, our heat pump maintenance checklist covers everything—reversing valves, defrost cycles, refrigerant levels, and more. We inspect and clean both indoor and outdoor coils, making sure the system can efficiently transfer heat in either direction. Our team checks the thermostat for seasonal accuracy and verifies that the switch between heating and cooling modes is smooth. We’ll also test motors and electrical components for wear or inefficiency. If anything looks off, we’ll catch it before it becomes a bigger problem.
A good furnace tune-up starts with a thorough safety check. We examine the heat exchanger for cracks, clean flame sensors, and test carbon monoxide levels to make sure your home stays safe. The blower motor gets cleaned and lubricated, while belts and electrical components are inspected for wear. If your system uses natural gas, we’ll check the gas lines for leaks and verify that ignition is working correctly. Once we’re done with your furnace maintenance, your heater will be clean, safe, and ready to keep your home warm when you need it most.
The best thing you can do at home is to change your air filter every 1 to 3 months and keep outdoor units clear of debris. For everything else, call Guthrie & Sons!

Just installed yesterday, so jury is still out on the system, but installation was thorough and great communication so far!
Updated review: Kareen, Daniel and Michael worked on the AC replacement, relocation of furnace to the attic and replacement of ductwork. Very professional and knowledgeable team in my opinion. Completed the work in a timely and very satisfactory manner.
