"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.

"Ozzie is extremely nice, very professional, and puts out the extra 9 yards to give his clientele good service. This would not be complete without mentioning Alberto. He installed a new HVAC unit for me. Working through the heat, humidity, lifting heavy parts both outside and upstairs, the air handler system, I would estimate he had the WHOLE job finished in 7 hours. Seems to me record breaking time, when you consider all the dismantling, carrying, cleaning up of the premises. So Ozzie and Alberto, hats off to you both!! And, I was able to go from 93° upstairs to a most comfortable 78°, perfect sleeping!! Thanks again! Hire them!!!"

"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

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.
