"Excellent.
Very professional and honest business.
Howard cleaned 2 separate air conditioning zones and also the dryer vent.
He returned about a month later when we had an unrelated air conditioning issue and helped us out at no charge.
Would very highly recommend.

"I cannot thank “Natural Breeze” enough for the fantastic job they did installing my new hvac system. I had previously committed to doing business with another hvac company during the heat wave who did a horrible and incompetent job with my hvac system. It was truly a horrible experience but thank god I was able to get out and terminate my contract due to their negligence. I was referred to Luis whom I reached out to and he responded to my emergency situation quickly. He is truly a reliable professional and having talked with him he is extremely knowledgeable and informative. He is a man who works diligently and has great morals and integrity. I am a dedicated as a life long member to Luis and his team, he goes far and beyond to make sure his clients are completely satisfied and his prices are definitely reasonable. Thankyou Mr Luis and to your crew for the exceptional work that u have provided. I highly recommend this company if you are looking for a A+ hvac contractor ."

"Chris was great. He gave an estimated arrival time and kept me posted about when he would arrive. Once he arrived, he was very professional and respectful of my home; he didn't even mind my nosy cat. He gave me an assessment of possible repairs needed on my portable AC, gave me an estimate for possible costs and provided an invoice on the spot. He made the whole process very easy, and I appreciate the time he took to explain everything. I would definitely hire DG HVAC & Home Services again for my appliance repair."

"Two days ago my central air conditioner stopped working. But today I feel lucky that Mustafa the technician from Angies list PRIME AIR LONG ISLAND arrived to service it. Mustafa was very professional and easy to talk to, he made his work look easy and got my AC working in no time. And best of all was when he handed me the repair bill, it was much lower than I expected. Mustafa is my new go to technician for Heating, Cooling and Plumbing jobs!"

Air Conditioning questions, answered by experts

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
