"I called and they sent someone out the next day. They were prompt and efficient and most of all the swamp cooler was repaired. The price they charged was excellent. I also signed up for a maintenance contract based on how well they took care of this problem. There are not a lot of places left who service swamp coolers so this was a good find. I have already recommended them to my sister for service on the air conditioning system in her home."

"This was the second time Tim has done work for me. He installed the heating system two years ago and now the central air conditioning. His crew was very fast, clean and pleasant. I could not ask for better service.. My son, who is in the business out of state, said the price was very good."

"Arrived on time and fixed the problem. A bit more expensive than I would have liked but checking around probably not much more than elsewhere and our air conditioner was fixed same day in the middle of a heat wave."

"I cannot express in words how trusting and reliable Highland Air is. My AC unit stopped blowing cool air. It was just blowing room temperature air. The last time this happened, I had to pay a ton to get the compressor replaced by another company. That company took advantage of the fact that it was 98 degrees and charged me $3,800 to replace it, knowing that my choices were limited. Shai knew the urgency and to my surprise, he found that it was the capacitor and not the compressor this time. The pricing was more than reasonable, and he was the first to get here out of the many companies that I called. Anyone who has had any work done on their home knows how important it is to trust the companies that you do business with. Shai was able to replace the capacitor within minutes and fix the issue. I will obviously now be a life-long customer."

"Replaced my gas furnace and air conditioner with a heat pump. The only company I contacted who did a thorough analysis of my home and electrical system to determine exactly what I needed. Side note: I requested this service because my furnace quit working. The technician who came out to evaluate my home repaired the furnace for free while doing his analysis. I still bought the heat pump, but this company definitely did not simply try to just sell me one."

FAQs for air conditioning projects in Thousand Oaks, CA

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.
