"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

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.
