"I called Holmes Air Conditioning and the phone was answered by the owner Bart Holmes. I explained my issue which was my home air conditioner would turn on but would sometimes blow hot air. After talking with me for a good 10 minutes, Mr. Holmes set up an appointment to meet with me at my home the next day. He met me at the time discussed and spent well over an hour diagnosing and going over options with me. Because the a/c only does this some of the time and was working properly he told me that my best option was to wait until it did it again and then call him back so he could properly diagnose the problem before I dump money into it chasing possible solutions. I believe his professionalism and honesty is rare in South Florida and almost unheard of in the air conditioning business. The charge for the service call and hour of his time was $50.00. If you are searching for some integrity, I can highly recommend Bart Holmes."

"These folks are great!  The first couple of years that I had this central AC installed, the main HVAC unit would freeze up and flood the closet and adjacent areas.  
After paying another company for the same repair for three years, I finally ditched them and called Weathershield.  They came out, noticed that I had a bad thermostat, replace that, serviced the unit and I haven't had a problem since then. 
The folks are super polite, arrive on time and have had my AC purring now for over four years now.  Can't say enough.

"My A/C unit was leaking due to dirty coils. I needed a repair quickly and Air Supply was able to do that. Had some initial hesitations about the cost, but the owner took the time to reach out and negotiate a price I was more comfortable with."

"Silviu and his 2 assistants came out to check on what I thought might be a duct leak in the attic. It turned out our ducts are undersized and need to be replaced for the unit we have. Silviu was very professional, informative and answered numerous questions. Currently our budget can't replace the ducting system but as soon as it does I will strongly consider hiring him to do the job. We were not charged anything for the visit and I deeply appreciate his advice and information! I do believe he is honest and fair and would not hesitate to hire him for your air conditioning needs."

"I had my complete 4ton air-conditioning unit replaced by East Coast AC & Refrigeration and I was extremely satisfied. There technicians did a beautiful installation and were very careful to work cleanly and had my new system cooling quickly. I have used East Coast for over 15 years because they have always treated me fair and they provide quick, professional work and use quality equipment while charging reasonable prices. I highly recommend East Coast AC & Refrigeration to family and friends as I have always been happy with their services."

FAQs for air conditioning projects in Deerfield Beach, FL

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.
