"This was my first annual maintenance on my new Lennox gas furnace. Alex showed up on time and went to work immediately while clearly explaining to me the maintenance he was doing on the furnace. He clearly and thoroughly answered any questions I had. He even took off his shoes when going up into the house to adjust the thermostat. He did a great job and I look forward to him maintaining my furnace and ac units in the future."

"They just installed a new furnace and air conditioning unit. The value of the services was similar to others compared, but the timing, the products they installed, and overall communication is the reason we chose them. From sales to installers, all were courteous, honest, and gave great communication."

"Paul, our service technician, was timely, knowledgeable, and efficient. I can highly recommend Heritage Home service on this account. However I am extremely unhappy with the company's new service plan offered. I will explore other providers for this reason, and may not use Heritage Home Service in the future."

"Quick Response - Quick Fix! Called at 10:00 am to confirm an appointment to fix my dead AC Condenser (Aug. 14 so you know I was not the only one having AC issues); Eric said he would be at the house between 2:00 pm and 4:00 pm that afternoon and would call when they were on their way. Eric called at 2:15 pm, was here before 2:30 pm, he and the other technician (I forget his name, sorry) diagnosed the issue as a bad Compressor Start Capacitor and we had our AC unit back up and running before 3:00 pm! Great Job!"

"Excellent. Don was the best contractor we interviewed and worked with in 25 years of home projects in New England. He was professional, personable, very easy to work with. He communicates very well and clearly what he plans to do, updates along the way, if any issue arise, and gives very helpful and skilled recommendations for solving issues or improving design. Quality of work was exceptional. Very detailed for finish work. He also works very fast and efficiently. He was on time or ahead of schedule for most of the projects. He was on or under budget as well for two large projects which was very impressive. I absolutely will choose Handyman911 first for my next project."

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