"I had used a bigger company for all my HVAC service for years. They did good work but I always felt like I was being overcharged. Many people in my neighborhood recommended JJB Mechnical. Juan managed to come out days sooner, quickly identified the problem, and came back a couple days later to fix. Highly recommended!"

"Great work done by Voda! Eric was on time and professional. He took the time to thoroughly assess and create a plan. Having 2 kids my area rugs are always disgusting but they have so much life left after his deep clean. He also cleaned my couch! He even checked some places I thought could be mold forming in the basement and assured me it is not and our family is safe! Voda has a long list of services they offer and I will keep them on speed dial! Thanks Jared and Eric!"

Small jobs welcome

Hello everyone I'm Nick, Im a 37 yr old with 20+ years of working with my hands on all sorts of jobs. From framing houses in my younger days to running small crews doing HVAC. I've also done full hard scapes both installing and repairing/ reviving along with your normal small home repairs. I'm very knowledgeable and take pride in my work. I have most tools to do any job but depending on the job I may have to rent or purchase that tool required to complete the job. I am goal oriented and focused at doing the job right the first time. I have a sharp eye for detail and am not a lipstick artist if you know what I mean. The job will be completed correctly. If you hire me you can be certain to be treated with respect and honesty throughout the process along with a fair cost for the job. \n\nThank you for the opportunity and I look forward to hearing from you.

Heating and Air Conditioning FAQs, answered by experts

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

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

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
