"Originally I called for a diagnostic of my AC unit, which was doing a terrible job cooling my house. Nikita did the diagnostic-turns out the coolant was leaking, a coil needed to be replaced, and not to mention the thing was from the 1990's. We decided to replace and upgrade it, as well as our furnace, since we froze last winter (turns out it was badly rusted on the inside and emitting CO into the house, which NO ONE found last winter (had it looked at by 4 different people and everyone said there was nothing wrong except that the BTU's were too small for the size of the house). Roy was so awesome, because even though they couldn't schedule us for the next 3 weeks, he made sure we stayed cool-he filled up the coolant and came over to the house a couple times when the AC stopped working. I will be keeping him as our heating and cooling guy!"

"Contacted Dan Dugan for an estimate on a new installation. Old unit had been running with bandaids for a couple years and was beyond its life expectancy.
While I was sticker shocked at the price, I found out these heat pump systems are much more complex than a standard gas furnace. I also price compared and found this price to be within the customary range with installation.
Dugan (Bryant) offers a hard to beat 60 mo. Zero % interest financing through wells fargo Bank. Why use my own money?
Installation went down without a hitch. While this was my sons home, I sort of managed the project as he works a lot of hours. He basically let the installers in and do their thing while he went to work, so no inconvenience on either of our parts.
Installers were in and out same day, left no mess and everything runs great!
Definitely recommend Dugan Air!

"Called Hope Plumbing for a leaking sink that the technician (Jarrod) ruled was likely due to hard water buildup. I has assumed this and mentioned we were having an issue with our Softener backing up into the basement. Even though I didn't call them to work on the Softener Jarrod quickly determined a fix for the softener flooding our basement and said a simple Air Gap drain would help prevent it from backing up. He quickly put together a quote that was reasonably priced and within a few hours fixed an issue that had been plaguing us for months. The service was fantastic and I highly recommend joining their membership program for some great benefits!"

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.
