Benefits of HVAC Maintenance

Save up to 30 percent on your heating bills – an HVAC system that runs efficiently costs less to operate than one that is having problems. When the unit is under stress from malfunctioning parts or worn belts, it takes more power to operate, costing you more on your energy bill.

Find problems before they lead to unnecessary breakdowns and costly repairs – during the off season your air conditioner or heating system can develop tiny cracks, bits of dirt, and other imperfections that can damage it, preventing it from running properly when you need it most!

Improve comfort and temperature stability – we will check the thermostat calibration and make sure it is communicating properly with your HVAC system so your home temperature is as accurate as possible.

DOUBLE the lifespan of your heating and cooling system – did you know that over 40 percent of HVAC breakdowns occur because the system was poorly maintained? HVAC maintenance will add years to your system’s life.

Reduce the need for untimely replacements – without HVAC maintenance, you never know if there’s something wrong with your heating or cooling system that could be fixed before it causes your system to break down completely. Having your systems checked out once a year can find these issues before they become major disasters.

Dramatically improve indoor air quality, reducing symptoms of allergies and asthma – dirty components and clogged air filters are just some of the things that can cause poor air quality in your home, resulting in allergies and other breathing problems. Improved air quality is one of the best benefits of HVAC maintenance.

Safeguard your home and family – part of our HVAC maintenance process is checking your system motor’s voltage and amperage, checking operating pressures and other places where problems could pose safety hazards to your family. We will also ensure your furnace is not leaking carbon monoxide into your home.

Be environmentally friendly by saving energy – when your HVAC is running smoothly it uses less energy, which helps everyone in the end!

Have peace of mind knowing your HVAC system will last the entire season – with a vastly reduced likelihood of breaking down and optimized energy savings, you can be confident your HVAC system will keep you cool and comfortable all season long.
