"The person who handled my call was friendly and professional. She told me a technician would be at my house in 4 hours and called me when he was on his way. The technician was outstanding, on time, professional, friendly, and quickly diagnosed and fixed the problem...best of all, he didn't try to sell parts/service that I didn't need! Best experience with an HVAC company I've ever had."

"I always recommend Anton's to family and friends who need HVAC services. Their prices are reasonable, and their service is top notch! All of their technicians are very professional and considerate and they don't try to sell you things you don't need. Ronan just came out this morning to do our annual A/C inspection. The service was excellent as always. He took the time to explain everything and made recommendations. I never felt pressured, and I trust this company to take care of my HVAC needs. They've got a customer for life!"

Heating and Air Conditioning questions, answered by experts

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
