"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 !

"Skyline HVAC did an excellent job installing my AC. The installer was professional, on time, and clearly knew what they were doing. They explained the process, worked efficiently, and made sure everything was installed cleanly and correctly. Before leaving, they double-checked that the system was running perfectly. My AC works great and I’m very happy with the service. I’d definitely recommend Skyline HVAC to anyone needing quality HVAC work."

Heating and Air Conditioning questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.
