"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"I've been using Central Suffolk Mechanical for my AC and heating maintenance for a number of years at 2 houses in Suffering lol County. Work is always performed professionally and timely. Extremely reliable service. Also had a hot water heater and a central AC unit installed, again done professionally and at the time and price promised. I highly recommend Joe and his crew for all HVAC needs."

"Fast responsive to my inquiry. Came to see job. Quote came quick and was one of the best out of 5. I immediately admired the professionialism of everyone in the company who I spoke with. I agreed to go ahead. The two workers were very prompt and polite at all times. This job took an entire day. They rang my doorbell to let me know they were going for a replacement part so that I didn't think they weren't going to finish. They returned and finished the job. Very likeable, professional young many dealt with me and the payment. He could not have been nicer or more businesslike. Having been a small business owner for forty-five years, I know a great employee when I meet one. This company was very well represented by this young man. They did a fantastic job leaving my tennis court bright and clean and the brick patio spotless. I would highly recommend them for any kind of cleaning job that they offer. A+ business, a true pleasure! L. Curtis, Remsenburg"

"Flawless. Called Anthony 1 week ago. Got prompt callback. Was here next day. Scoped out and priced the job, gave me installation date for following week/ 7 days start to finish (included a weekend and a holiday! Very fast, professional installation by Anthony and his partner. Up and running in 90 minutes. Extremely happy. Will use him to replace our other unit in the Fall.

"I am very happy with Mikes Air Conditioning. Here it is JULY and I while in the middle of doing some renovations to my home, I noticed the AC wasn't working the way it should be. I contacted Mike's (fearing the worst) and they sent out a service technician who was able to repair the system for a reasonable cost and buy me some more time before I have to replace the entire system. I had some minor work completed and the freon topped off and now I'm cool and comfy!  Considering all of the expenses with renovating I was very happy to not have a high repair bill. Mikes was efficient, conscientious and professional and they completed the job on time and for a reasonable cost. I recommend them for AC repair as well as installation of new units. When I'm able to replace my system, I'll be calling Mikes Air Conditioning to do the job. Building relationships and getting repeat business should be the goal of any business. I'm glad to see that Mike's takes customer service seriously.

"He was prompt. He didn't really do anything. He put the air conditioner on. It did turn on and it was blowing cold air. He did go up into the attic and inspected. It was just a visual inspection. It wasn't anything like he checked the valves or any of that. It was like a 1, 2, 3 kind of thing. He did what he had to do. He was there within 15 minutes after my mom called him. There were no additional charges beyond the big deal amount. Nothing was changed. No filters were changed. It was just to see that it was working. It was an older unit and it had never really got that cold. So I wanted somebody to take a look at it. Take a look at what's working and what might not be working and then make a recommendation for repair or replacement. As far as measuring or testing the actual temperature and looking at the level of Freon that was in the system, I don't think he did that."

"Extremely well. Was able to get an appointment right away. Other companies either gave me an appointment a week or 2 away or did not respond. Technicians came on time, were professional, and cleaned up after themselves. They worked on the dryer and vent for almost 2 hours. They explained to me clearly what they needed to do, and it now it sounds and works like new."

"It went very well!! The steam cleaning really gets rid of all the dust, grime and dirt that accumulates over time. It gets into all the nooks and crannies that you would need a toothbrush or toothpick to get clean. I feel like my house has never been this clean, and floors have never been this shiny. I would highly recommend them - extremely professional and takes pride in their work."

FAQs for central humidifier installation and replacement projects in Southold, NY

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
