"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

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.
