"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 !

"Jose responded quickly. He was willing to help my senior mom understand the issue with the HVAC. He also showed her how to work the thermostat. He took pictures for me and made sure the job was done right."

"The specific work performed was to seal a Freon 22 leak in the outdoor coils of a 14 year old Trane XL15 unit. We had our previous a/c contractor out here in May, and they never even attempt to tell us there was a problem. Then we had another local contractor diagnose the leak, on their second visit and after wasting $500 worth of the Freon. They said it was impossible to repair and were going to quote a totally new system at around $4,300. I then went to the Trane.com site and found RCI Air. I called early this Monday and was happy to speak with Mike the owner. He sent out Lazaro the Technician, within the hour. Lazaro had it quickly diagnosed and explained all of possible options. He sealed the leak using a special epoxy compound that when heated, will seal cracks on aluminum pipes. Lazaro spent nearly 3 hrs. making the repairs and properly recharging and checking the system. This is day two and the air is coming out nice and cold. If you have an older Trane brand unit, I highly recommend that you call RCI air."

Heating and Air Conditioning questions, answered by experts

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

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.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own.
