"Good reliable company who I’ve dealt with for quite some time. Reasonably priced I’ve had the annual contract with them for a couple of years. I just had my furnace serviced for the winter. Christian did the service. Very pleasant young man knowledgeable"

"On time, professional, easy to work with, willing to trouble-shoot and think outside the box to determine the cause of the furnace problem. Had suggestions for further upkeep and service, should the time come. Replaced parts that should have been changed and/or replaced and cleaned by former company, but were neglected for the last three years. Was reassuring that the entire furnace did not need to be replaced!"

"The guys were on time, cheerful, thorough, and and got the job done. They were thoughtful about my cat, too. The 'sanitization' stuff they sprayed did smell for a few days, despite my airing out the house with the windows open, but it did eventually go away. And they must have gotten a lot of dust out because my children (who are usually very sneezy with the dust pumping through our house) have seemed much better since the ducts got cleaned. Very happy with the service. I used an Angie's List "deal" for the service--I was in a hurry to get it done (my kids had dropped some art supplies down a vent that were making clicking noised that were driving me nuts) so I didn't compare prices at all, I just looked for a company that seemed thorough and they they were. And the clicking sounds of rogue art supplies is gone. Yay!"

"My experience with Atlantic was one of the best - if not THE best - I've ever had with home maintenance and repair companies!

Since I'd never had the heating/AC ducts in my house cleaned in the 20 years I'd been here, I solicited estimated from three companies.  This one had been recommended by my oil company owner, who said that it had been recognized in the industry as doing high quality work.  All three estimates were about the same, but the owner of Atlantic, Jack Prindiville, impressed me as being far more professional and knowledgeable than the other estimators.  He patiently and thoroughly answered all my questions, and I was scheduled to have the work done very promptly.

I couldn't have hoped for better workmen than the two young men who did the work.  They were fairly young, professional, efficient, hard-working, and extremely good-natured.  They completed the job fairly quickly, but thoroughly, and left no trace of any mess.  This was an A+ experience in every way!!!

FAQs for air conditioning projects in South Windham, CT

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
