"I called Weathershield because the pipes in the ceiling were dripping water from condensation and had ruined several placed on my ceiling.  Some of the vents themselves were "sweating".  Elizabeth answered (very professional and very delightful to deal with!) and I explained the problems.  When the technicians arrived they were very professional and soon identified the problem.  They removed the evaporator coil which turned out to be extremely dirty and used a special chemical to remove all of the dirt and debris from the unit.  They also removed the blower wheel and housing and thoroughly cleaned the blower wheel, motor and housing.  They performed a condenser flush and checked and adjusted the freon levels.  They stayed and made sure the unit was cooling properly.  I am so very satisfied with the service from this provider and the price !!!  I will definitely call them again and recommend them to anyone who asks !

"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

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

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, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.
