"We have been in our home for a little over a year and thought it best to have our furnace serviced especially since we don't have a detailed history of service. Frankie D showed up 5 minutes early for our appointment which was fantastic. Frankie was quick, clean and gave me a once over on the age and condition of our furnace. We talked about when the next service would be due. I couldn't have asked for a better experience and I am thankful that we now have our go to company for anything furnace related."

"He was timely, professional and responsive. He clearly knows the technical aspects of the trade and provided us with a lot of information about the equipment he would be installing and how it would work with our existing ductwork.  We did not care for his sales approach because he tried to sell us on things we did not ask for and did not need.  He tried to sell us on a humidifier for the system which we really don't need because we live right by the ocean where it is quite humid year round, even in the winter. Adding humidity to our house could cause problems with mildew or mold.   He also tried to sell us on replacing our hot water tank for a more efficient model even though ours is only 5 years old.  We got the feeling that he was trying to pack as much sales onto the heat loan program without really thinking about the customer's specific situation, and that put off me and my husband from wanting to work with him.  At the end of his sales presentation he decided on the spot he would give us an unspecified discount.  We did not like this high pressure sales tactic.  We had not received other quotes yet so we declined to decide on the spot.  He emailed us a couple days later offering a 10% discount if we decided by a certain date a couple days later.  We decided to wait beyond that date so we could get more bids.
Joe's quote was $2000 higher than a quote from another installer who has equally good reviews on Angies list.  Both quotes were to install the same equipment, however the second installer included the cost of converting two unused ducts into returns and installing a pass though in a ceiling to help balance our system.  I shared this information with Joe, and he responded by saying he would beat their price by $100.  It goes to show that it pays to shop around. 
As Airco's good reviews on Angies list attest and my interactions with him, I am sure they would do quality work, but my husband and I were totally put off by his sales and pricing approach and did not want to work with the company as a result.

"We were having an issue with our heating unit leaking water everywhere in our basement. David from Palmer Gas & Oil came out to do our safety check and after giving us a passing grade, immediately starting working on our problem. We did not have to call to have someone else come out after the safety check was done. David took care of the issue while he was there. He was extremely pleasant and easy to work with. He had our problem taken care of in no time. Awesome customer service!"

"It was quite a surprise to find black mold growing in our mini-split heat-pump/ac units over the weekend! The situation was quite dire with the system emitting a bad smell and the fact that I have asthma and mold allergies which posed a serious health risk! After being told by the company that originally installed the system, “We don’t provide deep cleaning service for these units, try looking on Angie’s List (boo on Sila!)” I landed here. While other companies did respond to my bid, Atlantic Heating and Air Conditioning was the most responsive and was able to send out a team on one day’s notice (the wait for other service providers was up to three weeks!). The tech team, Josh and Zack, arrived on time and called me 1/2 before arrival as promised. They were very respectful, kept a clean work space and (since we are in the middle of a pandemic) wore masks and were very careful about the usual COVID protocols. The four units in our home are now SPARKLING CLEAN! We are 110% pleased with this job!! We will hire Atlantic as need be in the future for our heating and cooling needs. I have given up on the company that originally installed the units and will post a truthful review about them in an appropriate space online. I would definitely recommend Atlantic to family and friends. (photos attached to this review show one of the units before cleaning - did not think to take after pictures. Suffice it to say, no more mold:)"

"Great! Owner was the one providing service - prompt arrival, quick getting the appointment (next day; I wasn't in a rush). Took care of the problem quickly and at very reasonable price. I've had this work done by another firm (rhymes with Toto Tooters) about 8 years ago and this was nearly half the cost!"

"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."

"I am a person of modest means; because of APM I was able to replace my heating system at a price I could afford. APM helped me choose the right appliance that I then ordered online to save money. Appliance did not come with a part I needed for my specific installation; they educated me about the part, I was able to do an internet search and obtained the item on Ebay for a steal. Service quality was top notch, easy to work with, great communication via email and phone, worked clean, very nice people. I feel very fortunate to have had this service experience and would highly recommend this company.

"My wife call Jake, he came out looked at what needed to be done. He contacted the town water and sewage department and found out exactly what was needed. He pulled the permit, ordered the meter and called to let us know when it should be in. Once it arrived he called again and we firmed up the date for the install. Meter was installed, town inspected and everything worked just fine. Very professional and polite. I would highly recommend this gentleman and certainly will use his services again."

"The gentleman from Dudley spent a full 30 or 40 minutes on the phone with me to discuss a home that we were considering purchasing.  He went as far as looking at the property in MLS, scanning public records for asbestos removal projects performed on neighboring streets, and even looking at the development in Google Maps to confirm that nearby houses seemed to be the same age and design.  In the end, he recommended that we contact an independent testing laboratory and helped us understand what we should be considering with respect to this home purchase.

I had originally contacted them to get ballpark pricing about hypothetical things that *I* could imagine.  Instead, he made it far more concrete by looking at the home and telling us what we should be considering and what it would mean.  None of this yielded business for himself, but as you can imagine, I wouldn't hesitate to call on Dudley Services, if I found myself needing their assistance.  These seem to be precisely the type of people with whom I'd like to do business.

FAQs for window a/c unit service or relocation projects in Concord, NH

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
