RC&G is an acronym - it stands for "Richard, Charlene, and the Girls", because it's a great reminder of what I'm working for. I'm Richard and my wife and daughters are the most important thing in the world to me. Also hugely important to me is doing great work in my business as a handyman. I've always been mechanically inclined and good at fixing whatever's broken. With decades of experience, now I'm truly a master handyman. Whatever you need, I'm here to get it done. I respond quickly to contacts and give an accurate estimate. Then I arrive as scheduled, do the job right, and leave your house as clean as I found it. I'm looking forward to meeting you!

"Richard was friendly and kind. He installed our blinds, helped clear our sink, fixed our screen door, and assessed our TV mount— all in an hour. We’d love to work with RC&G. As someone with mini houses fixes and projects it can be intimidating to ask for help, but RC&G showed us most things are fixable."

"Review I left on Google. We had an amazing experience with Smart Heating and Air Conditioning. Our tech, Juan, was on time, courteous and knowledgeable. He fixed the problem quickly and offered expert assistance in setting up an ongoing maintenance plan for our 35+ year old furnace. Also, he was engaging, and focused on the customer experience.

Heating and Air Conditioning questions, answered by experts

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

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.

Yes, high-efficiency models reduce environmental impact with lower energy use.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

No, a licensed local AC repair technician must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.
