"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!"

"This is my 3rd service call completed by Peterson Plumbing.  The bearings on my disposer were going, making a nasty noise.

I bought a replacement unit and had Paterson replace it.  the job was done properly and promptly and for a price that makes doing it yourself a thing of the past.  He cleaned up and left the place the way he found it.

Thus another job by Peterson was completed."

"Vermiculite abatement, as we learned, is a complicated and expensive process. Sam explained all of our options and his recommendations to keep the costs as low as possible, including available assistance from the state. We had to vacate a portion of the house for several days to accommodate the equipment and the need to prevent contamination. The crew showed up when they said they would and worked efficiently, so we had the space back when promised."

"Excellent service from beginning to end. I first called to request the service, I could not speak with any members, but they promptly returned my call, understood the request and made an appointment. The day of service, the technician arrived on time and explained the work to be done and eventually his findings. He was very polite, professional and knowledgeable. He also gave us tips on how to better maintain the system for improved performance. Overall, excellent service. We highly recommend then and we will definitely use them again"

"I called the company based on other reviews. They were courteous, pleasant and helpful on the telephone and I got an appointment within a couple of days. The technician, Nicholas, arrived promptly and covered his work area with a drop cloth. He quickly diagnosed the problem and had the part on hand for the repair. He said he could reposition the logs correctly with no problem. He also cleaned and reconditioned the entire log set, both sets of glass and the entire back of the unit. He vacuumed the entire area before leaving. The fireplace looks FANTASTIC and operates perfectly. The attention to detail and pride in his workmanship that Nicholas brought to his job is extraordinary. I've already recommended him and the company to a family member and they are wonderfully pleased, also. I'd rate my whole experience A+++!"

FAQs for window a/c unit service or relocation projects in Dunbarton, 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.
