"I had great experience with Shore Guys Heating and AC. Last year they replaced one of the HVAC units on my rental property and today Today Mike and Bobby changed other HVAC unit (two zone A/C). I have to say that I was impressed as to how Mike kept me informed during the day how everything was going, and at the end of the day they informed me what was done, sent me pictures and everything. I am very impressed with both of them. I would recommend Mike and Bobby without any reservations. Great job. Thank you."

"The specialist sent was amazing. He showed me everything step by step that was wrong with my HVAC. The house was constantly at 91 degrees and he fixed it all there and then. I had talked to many companies about the HVAC job I needed done. They all said they would â call me to schedule an appointmentâ but this gentleman reached out came within the hour showed me everything that was wrong. He fixed it all in well timely manner, he was clean, and very polite. He will give you the best prices. He is a hard worker and very knowledgeable. He will be maintaining my hvac system from now on. Would recommend 5/5"

"Excellent service. Got brand new HVAC units and had the coils replaced. They were thousands less than the other three bids. Came in laid drop cloth to make sure nothing would be tracked in. Very polite and quick and cleaned up when they finished. A++ Service will recommend and hire again."

Heating and Air Conditioning FAQs, answered by experts

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.
