Called NRG Heating and Air, not only did they come out through same day, they gave me a price that I simply could not say no to and to my surprise they came and did the work the next day. NRG will have recommendations coming from me forever. Thank you"

"It was fine. There was an additional charge but I'm not surprised because I had a dryer vent that is very complicated. We negotiated and told me what they will going to take to do it. I was fine with it because I know my dryer vent. For me, to call somebody and do that specifically, it would have been more money. I feel good about it."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"My friends had installed a new HVAC system and they told me that the system improved the monthly utilities bills and the house is always warm. I contacted the company that made the installation and I spoke to Ezra. Ezra provide me with some basic information about them and about the system that they installed at my friend’s house and he asked me to pass by and look at my house in order to determine what will be the best system for my house. Ezra arrived to my house and checked the existing system and he explained to me the differences between that one to the new one. I decided to hire them and to go for the system. Before the installation, Ezra came over and did a special test that took close to 4 hours. He covered all the windows and ducts and ran a special machine that supposed to check and detect any leaks of energy. The end results of the test came out good and this was a good relief. The installation of the HAVC system went smoothly and without any issues. The work took 2 days and the new system start to prove itself. I must admit that I’m happy that I was referred to this company and that I hired them for this work.

Heating and Air Conditioning FAQs, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

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.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with.
