"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

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork.
