"I spoke with James about cleaning my air ducts. He explained the process to me and followed up with an email that included the same information, along with the appointment scheduled for the next day and the total cost. When Mike and Shawn arrived, they introduced themselves and immediately got to work. They asked a few questions and showed me how much dirt was in the ducts. I didn’t take pictures, but you can imagine these air ducts had probably never been cleaned before. I would recommend Central Penn Air Duct Cleaning to anyone who is interested. From customer service to completing the job, these guys are straightforward and professional."

"Did a great job, I talked to 3 different contractors, glad I did Chuck educated me every step of the way. Secco Home services ripped me off for $800 to diagnose and charge my system then came back with a equipment quote that would have been wrong for the situation. Avoid Secco at all cost. Call Total Heating and Cooling!!"

Heating and Air Conditioning FAQs, answered by experts

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
