Everything Your System Needs

Whether your heating system won’t turn on, your AC is blowing hot air, or you need a complete system replacement, we handle it all. Emergency repairs, routine maintenance, new installations – whatever your HVAC system needs to keep your home comfortable.

Millis homeowners deal with everything from humid summers to freezing winters, and your HVAC system takes a beating. We know which systems hold up best in this climate and how to maintain them so they last longer and run more efficiently.

Our service includes thorough diagnostics, quality repairs using proper parts, and maintenance that actually prevents problems instead of just checking boxes. When we’re done, your system works the way it’s supposed to – quietly, efficiently, and reliably.

This usually happens because of a refrigerant leak, a failed compressor, or electrical issues with your outdoor unit. Sometimes it’s as simple as a dirty air filter restricting airflow, but often there’s a more serious problem that needs professional attention. The key is getting it diagnosed properly instead of guessing – we see homeowners waste money on the wrong repairs because they didn’t identify the real cause. A qualified technician can test your system’s refrigerant levels, check electrical connections, and pinpoint exactly what’s causing the problem so you get it fixed right the first time.
First, check your thermostat batteries and make sure it’s set to heat mode at the right temperature. Then verify your circuit breaker hasn’t tripped and your furnace switch is on. If those basics don’t solve it, you’re likely dealing with a more complex issue like a failed ignitor, gas valve problems, or safety system lockout. Don’t try to force it or bypass safety features – that’s dangerous and can cause expensive damage. Modern heating systems have multiple safety mechanisms that shut things down when something’s wrong, and a professional needs to identify why it’s not starting safely.
Most systems need professional maintenance twice a year – once before heating season and once before cooling season. This isn’t just about changing filters (though that’s important too). Professional maintenance includes checking refrigerant levels, cleaning coils, testing electrical connections, calibrating thermostats, and identifying small problems before they become expensive repairs. In Millis, where your system works hard through both hot summers and cold winters, regular maintenance can extend your equipment’s life by years and prevent most emergency breakdowns. It’s much cheaper than replacing major components that failed because of neglect.
Age is the biggest factor – most systems last 15-20 years with proper maintenance. If yours is approaching that range and you’re dealing with frequent repairs, rising energy bills, or uneven temperatures throughout your home, replacement often makes more sense than continued repairs. Also consider if your system uses outdated refrigerant types that are being phased out, making future repairs expensive. A good contractor will give you honest numbers comparing repair costs versus replacement benefits, including energy savings and improved reliability. Don’t let anyone pressure you into immediate replacement unless there’s a safety issue.
Emergency service means we’ll get your system working again when it fails during extreme weather or creates unsafe conditions. This includes diagnosing the problem, making necessary repairs to restore heat or cooling, and ensuring your system is operating safely. We carry common replacement parts and can handle most emergency repairs on the spot. However, emergency service focuses on getting you comfortable and safe – sometimes that means temporary repairs that need follow-up work during normal hours. We’ll always explain what we did and what additional work might be needed to prevent future problems.
Start with regular filter changes – dirty filters make your system work harder and use more energy. Programmable thermostats can save significant money by automatically adjusting temperatures when you’re not home. Sealing ductwork leaks and adding insulation also helps your system work more efficiently. Professional maintenance keeps your system running at peak efficiency instead of struggling with dirty coils or calibration issues. Sometimes simple repairs like fixing refrigerant leaks or replacing worn parts can dramatically improve efficiency. We can evaluate your specific system and recommend the most cost-effective improvements based on your home’s needs and your current equipment’s condition.
