"These folks are great!  The first couple of years that I had this central AC installed, the main HVAC unit would freeze up and flood the closet and adjacent areas.  
After paying another company for the same repair for three years, I finally ditched them and called Weathershield.  They came out, noticed that I had a bad thermostat, replace that, serviced the unit and I haven't had a problem since then. 
The folks are super polite, arrive on time and have had my AC purring now for over four years now.  Can't say enough.

"Fixed my poor ventilation of my dryer duct. Don't know how effective the hvac duct cleaning was. I figured it didn't hurt to do it once since it's never been done but mostly purchased deal for dryer duct."

"The absolute best HVAC contractor you will find! Honest, Trustworthy, Professional, Accessible, and fair pricing! There is no comparison. I unfortunately have used other companies before finding RCI and there were far pricier and unreliable! I am thrilled to have found RCI and will recommend them to everyone! I have already recommended them to friends who needed a new AC, RCI's pricing was the best of 3 estimates, and my friends were thrilled with their professional service! Look no further, call RCI confidently for all your HVAC needs!!! Thank you Mike and your RCI staff!"

Heating and Air Conditioning questions, answered by experts

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.
