"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"I've been working with this organization for about 2 years, perhaps a bit more, they have always been cost effective until this recent experience, they spent ~30-45min here at the house and identified the problem as a clogged pan drain,
the charge was ~300, i asked why the "high" charge and it was broken down as ~250 to come out and provide service, and another ~40 for the cost of the gas "nitrogen" to clear the drain,
these people have always been polite, professional, and effective, but, the charges have now become cost prohibitive, if you got the money and need a someone, these people are the ones i would recommend
i did call the business and explained my concern, i was told the message would be forwarded

"Jason and Noah did a great job replacing the old knob and tube wiring and installing a three-way switch on a dark flight of stairs. They worked on our project from start to finish, without interruption, which we greatly appreciated. They did a good job patching the holes they had to make in walls and ceilings in order to run the new wires. They cleaned up nicely at the end of each day and stored their tools out of the way in our basement overnight. At the end of each day, Jason gave us a walk-through of the progress he and Noah had made during the day. He had a positive, professional, "can-do" approach to the work and challenges of the project."

"Eddie did a fantastic job. He was able to come earlier, which helped me out. He explained what he was doing and got to work. One drain was a particularly hard job, but he kept at it until it worked perfectly. There were no hidden charges or attempts to jack up the cost. When he finished, he cleaned up completely. I would definitely recommend him and use him again if we need to."

"I had not previously dealt with All Phases Mechanical we were in the dregs of a awful heat wave when the AC went down..miserable. I had spent much money with The company that I used for 20 years they told me they would not be out for 4 days on a Saturday & because it was a Saturday would charge me a $500 premium or I could with until the middle of the following week. At 9:00 AM the same day I called Carl at All Phases Mechanical he sharpened his pencil gave me an estimate ,, sourced my replacement condenser... his very qualified experienced lead man Henry was exceptionally polite and knowledgeable. My AC system was up and running the same day by 4:00 PM Exceptional response and installatio . All Phases is my new company I highly recommend them"

"The entire process could not have gone more smoothly.  I called Stephen and he returned my phone call within the hour.  I described the area that I wanted to have cleaned and he came out the next day to give me a free estimate.  His estimate was reasonable and he was able to accommodate my schedule by coming out to do the clean up the next week.  He arrived promptly at 8:00 am - the agreed upon time - to let me know that he was there and if there were any last minute changes to the job.

He did a fantastic job and cleared away all of the brush, debris, etc.  Even better, I was only to send the payment provided I was satisfied with his results!  Who does that these days??

I would recommend Stephen to anyone and will certainly use his services in the future."

FAQs for central humidifier installation and replacement projects in South Lancaster, MA

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.
