"Itâ s so hard to find a reliable, trustworthy company these days. I happened to come across JJB Mechanicalâ s info when I looked at the service records on my furnace and decided to give them a call. When I say AMAZING it canâ t even begin to describe the level of service I received. Juan was great to talk with and showed true compassion and understanding when I explained my central air wasnâ t cooling and the temperature in the house had risen to mid 80â s by then. He had his Tech Daniel here later that day. I was blown away by Danielâ s knowledge and the way he explained things and educated me on what the issue was.

"After reading reviews about Kathy and her work, it seemed too good to be true. It isn't. I didn't bother contacting anyone else after meeting with her. Even though she is scheduled well into the future, we felt she was waiting for. In short, we couldn't be more pleased. She spent 13 days completely repainting our interior and it looks amazing. She was on time every day, easy to work with, and her work is incredibly good. We are already recommending her to family and friends, which we don't typically do. She's that good!"

Heating and Air Conditioning questions, answered by experts

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

Your air conditioner can temporarily run with a dirty filter, but it won’t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It’s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.
