"Had my spring maintenance done and couldn’t be happier with the service. The technician was on time, professional, and took the time to explain everything clearly they also swapped out my nest thermostat for an ecobee and got it set up. Everything is running great and I highly recommend Pass One Hour."

"B and D is very professional in all aspects of the work. Always on time, precise in his work, treats the job like he was working on his own home, has a great play list on his radio, and ALWAYS leaves the work site clean and neat. He even used a blower to clean off the front porch every night whether he worked on it or not. I have no reservations in recommending B and D for all aspects of your job. High quality!"

"Call this electrician! He s worth your call, don t wait for him to call you! He was fair, honest and went above and beyond our expectations. We got two other quotes, one being from another company (Service detectives) who charged us $89 for a QUOTE and then quoted us $19k for everything we wanted done. For the things we needed done (not the whole house but a new meter outside, wiring to the inside, new panel and several outlets rewired) Holtzclaw Electric did for 3 times less than S.D. Just call Brandon. You won t regret it."

I have worked in the construction field since 1999. I have done heating and air conditioning for the majority of those years. Working in the heating and air field is different that most trades because you have to be knowledgeable in electrical, plumbing, general construction, knowledgeable in indoor air quality and much more. Therefor I am open to provide heating and air conditioning and handyman services. No job is to small.

Heating and Air Conditioning FAQs, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
