I am married with 2 children. I am a volunteer fire fighter. I serve as a council member for my town. I enjoy doing small projects on the side ( evenings and weekends) I am comfortable doing most handyman work, if it's something beyond my knowledge I would recommend a professional.

"One zone of our two-zone HVAC system was not cooling properly. First, we got an estimate from a different vendor who recommended replacing the entire system (interior and exterior) without even attempting to diagnose the problem. We decided to get a second opinion and a neighbor suggested we contact Charles at Ocean Breeze. "HONESTY & INTEGRITY" is the name of the game for this company. Charles came to the house to investigate and first checked the interior unit to make sure there were no leaks. Then (according to my husband - not sure I have this exactly right), Charles disconnected the lines from the interior and exterior units and pressurized them to check for punctures or other signs of leakage.
After doing a thorough examination of the possible causes for faulty cooling, Charles recommended replacing only the outdoor unit. He took his time, examined the system thoroughly, consulted with my husband each step of the way, and replaced only what we needed. He was in our home 2 or 3 times without us being there and could've taken advantage ... but he did not. We were very impressed with his honesty and thoroughness, and would seek his help again in a heartbeat! Happy to write this review! (And thank you, Erik, for the referral!)

"Continental's technicians were highly experienced, professional, considerate, respectful, hard working, and neat. They arrived on-time when scheduled. Allied's drilling and trenching crews were excellent also. This was a big messy job that took about a week and we are very happy with the work that they did. The owner of Continental, Frank Jackson, sold us the system. He provided an extensive reference list that went back at least 15 years. He was on-site for most of the job providing hands-on supervision of his technicians. His technicians are so experienced that he didn't have to be there to supervise them. Rather, I believe he was there to make sure that the job was finished on time because they are so busy. Allied had an on-site supervisor at the start of the drilling process to finalize the location of the loop bores, but their drilling crew was highly experienced and needed no supervision.
Installing geothermal is a messy job. The vertical bores and horizontal trenching for the ground loop makes a muddy mess. The drillers from Allied were very respectful to the property, much more than I expected. I expected that the drilling process would make "a mess and a half" but it only made a mess! At the end of the job the ground was re-leveled and ready for seed, which has already popped and growing grass. As one of the drillers said "the mess only takes grass seed to fix".
The HVAC technicians from Continental left the spaces where they worked in "broom-clean" condition. We had to do some "deep cleaning" afterwards, but this was completely reasonable.
We expressed our concerns about the job to the technicians before they started work because we do not know much about HVAC or geothermal. They took the time to explain what they were going to do and how they were going to do it. They kept us fully informed about their progress and included us in the decision making process when they had more than one way of running a pipe or duct. They made us feel really comfortable and that we were getting a top-notch job.
While the cost for the system from Continental was a little bit higher than their competitors I think we got value for money. In addition to the reference list we received during the sale process, we also know two families that used Continental in the recent past and they are very happy with the work that was performed.
We would use Continental again and would recommend them to others.
If you go with the option to integrate your hot water heater with the geothermal system (which is supposed to reduce the cost of the hot water that you use) I would reccommend that you bite the bullet and have a preheat tank installed at additional cost. We didn't do that and in retrospect we should have based on some further reading that we did about how to get the most bang for the buck from geothermal. It would be easy to install the preheat tank during a new construction project. It would be harder to install the preheat tank during a replacement project (like ours was).

"Jim responded promptly to my order placed on Angie's List for the Remote Computer Tune Up & Repair Deal. He cleaned up the computer remotely, which was running very slowly, and required frequent re-boots. Computer is running much faster now. Great service. Would highly recommend.

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.
