"I cant praise Weathershield enough for the service they have provided.  I
 had previously paid another company to come clean my split AC.  It was emitting a moldly smell, which I assumed was becasue of mold and build up on the blower wheel and in the pan.  The first company used a strong smelling cleaner and told me it was clean.  It took 2 weeks for the smell of the cleaner to dissipate, and when it did, the old moldy smell was still there.  I took the unit half apart and could see a huge amount of build up still on the blower wheel and black mold growing on the interior of the plastic casing which covers and protects the coils and blower apparatus.
I called Weathershield and asked if they could have a technician call me back to discuss my situation.  I didnt want to pay - again-  for a service that wouldnt clean the unit properly and thoroughly.  The office had John, the head technician, call me back that very day and he described to me in detail how he would clean the unit, which was fa ar more involved process than the first company used.
I called the office back and Christina scheduled John to come and perform the cleaning the following week.  The office called the day before to confirm the appointment, and called the morning of to let me know that the technicians were on their way. John and his helper Hunter showed up right on time, placed booties over their shoes before they come into the house, and spent the next 2.5 hours carefully and thoroughly dismantling, cleaning. and reassembling the unit.   I was right there the entire time, and they took great care to explain to me what they were doing and why, without ever showing the slightest discomfort that I was there asking questions and watching the entire time.
The next day I heard a slightly unusual sound and called Christina, who scheduled John to come right back out.  He made a quick and minor adjustment and the unit is running perfectly now: smoothly, quietly, and the odor is gone.
I have lived in SoFla for 13 years, and this company gave the best service with the most professionalism that I have ever received since moving here.    Kudos to everyone at Weathershiled for their professional and technical expertise.  I will never use another AC company.

"We are very pleased. The service mam, Lazaro, was able to identify a minor installation error causing our problem. The problem had been missed by a previous service company. The total cost of this service and repair was less than the basic service from our prior company. The air conditioner now cools better/faster set at 79 than it did set at 77."

Air Conditioning FAQs, answered by experts

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
