"SensiGreen stands behind their work and product unlike any other construction/contractor I have ever seen in home work! We had some trouble with our air conditioner and they came out several times without any complaint until getting it just right. They provided us with "second mile" service going above and beyond what I expected in courtesy, professionalism, willingness to make sure we were totally satisfied, and in delivering a great product. Our home has their spray foam insulation throughout (walls and attic), their AC system, and even a UV system in the ducts to keep our air clean. I highly recommend them!"

"After spending a week without air conditioning, I called R&M Heating & Cooling. The 3-man crew that came out from R&M was highly experienced and very professional. In 2 hours my AC was working perfectly for a very fair cost. These guys are top quality professionals by any measurement. They know air conditioning! Highest recommendation! Like the last reviewer, I have an American Home Shield warranty & when my Central AC quit producing cool air, AHS sent out untrained, inexperienced technicians from Johnson Mechanical (twice) & they could not find the problem."

"I called Pure Air to see about having my dryer vent unclogged. The owner explained their a/c service; and, since my house is over 10 years old and I have an indoor pet, cleaning the duct work seemed logical.  I appreciated the fact that there was no pressure put on me to get the additional service, just a clear explanation.  The Pure Air technicians were professional, courteous, and apparently knowledgeable.  They explained each step of the service; and, since the builder of my house installed the dryer vent incorrectly, they  suggested improvements for a later date.   My home smells and feels cleaner since the works was done; and I can dry a load of clothes in 1/3 the time--saving on my electric bill and wear and tear on the dryer.   I will definitely use this company again.

On June 13, my air conditioner that services my upstairs failed (breaker kept tripping).  Called my home warranty company (Choice Home Warranty) and they assigned AL Comfort Experts to troubleshoot/diagnose issue.

On June 15, AL Comfort Experts came out as scheduled and identified that my compressor had locked up.  They reported this to Choice Home Warranty to effect repair/replacement of the compressor but CHW stated to me that it was reported that my unit was  'not well maintained' by AL Comfort Experts.  I contacted AL Comfort Experts and they not only told me they reported my unit had been 'well maintained', they also wrote/sent me a letter to that effect.  My issues lie with my warranty company, not with AL Comfort Experts.  I had several conversations with the owner Terry, for we both were a bit irritated with CHW. 

So, after several days of fighting with CHW over getting my unit repaired under warranty, it became clear that they would not replace my failed compressor, despite me providing them with almost 6 years of records of maintenance.  They actually told me if it had been serviced the week before, they still would not cover it.

It was through my conversations with Terry that I found them to have a high level of integrity.  AL Comfort Experts is a wonderful family owned company with many years of experience.  I found them to be very honest, forthright about the issues with my air conditioner and they provided me with a couple of options (repair or replace).  After comparing the costs, it was clear that replacement of my Trane compressor (proprietary and expensive), it was much better to do pretty much a complete replacement, as my current unit was 15 years old.  Made no sense to repair at this point.

On June 23rd, Terry (owner) of AL Comfort Experts and an employee came out as scheduled and did a wonderful job of not only installing my new unit and removal of my old unit, they did a top notch job of cleaning up.  Their costs were exactly what they quoted me (no one likes surprises).  There were very professional, came in a nicely marked vehicle, and introduced themselves upon arrival.  They answered all my questions I had and were meticulous in their work.  I especially like the system he provided me (Westinghouse) and explained the warranty to my satisfaction.

I have already given them permission to use me as a reference and have also hired them to do the servicing of both my Goodman main package unit that services my downstairs and the new Westinghouse system that services upstairs.  They have my highest recommendation!

FAQs for air conditioning projects in Princeton, AL

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.
