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!

"Project went fine. Richard was very professional and accommodating!"

"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. You’ve got a great employee in Juan Rodriguez Pinto. He made me want to be a recurring costumer to your business. Which, as a person who works in costumer service myself, is the highest praise I can give. In fact, the entire process for our service was seamlessly executed. From reaching out through Angi, to communications with Suzy in the office, all the way to a working furnace. It all added to a perfect customer experience. Thanks "

Heating and Air Conditioning questions, answered by experts

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

A new HVAC system can add 5% to 7% to your home’s value, especially if you upgrade the entire system, including ductwork and insulation. In total, these upgrades could bring around a 30% return on investment (ROI). Add a smart home thermostat, and your home’s value could increase because the heating and cooling systems are more modern, efficient, and convenient.

You should have your HVAC serviced at least once per year. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between $100 and $550 for HVAC maintenance, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.
