"The price i was quoted over the phone was not the final price for the service. The customer (me) has to ask more probing questions. I have two units to service and was quoted $159 per unit. I told them the units had some mildew and it needed to add refrigerant. The customer service put me on hold for a short time to check what she quotrd me. She said it was the correct amount. The final bill was iver $700."

"From start to finish we have had a great experience with Rodenhiser. Rick Picard came out to look at our system and provided a few estimates for different options while on site. We needed most of our 35 year old central air conditioning system replaced. The communication from the company was impressive. We always knew who was coming and when. They helped with the initial MassSave paperwork and even submitted all of the rebate paperwork for us when the install was complete. Good luck finding another company that will do the same. Our installers (Brian Heno and Dylan E.) arrived on time every day. They were professional, kept us updated on their progress and cleaned up daily. Two very hard working guys. They did a great job with the install. It looks and performs fantastic. We could not be happier with the system now that it is installed. We chose the correct company to work with. This is our second time having Rodenhiser complete a major install at our house. We had them install a furnace several years ago. I highly recommend them for your HVAC needs. Thank you."

"Punctual, professional, and repaired/properly installed a heating/air conditioning unit that had been previously installed incorrectly. However, we did not call around for pricing. After a poor experience with a lower cost service, we just wanted the job done right. We would definitely call them again."

"The service tech arrived a few minutes after the end of their arrival window. Reception did call to notify a slight delay. No big deal here. We reviewed the steps I took and after some preliminary inspection the tech revisited the system bleed. No air this time. It happens the boiler in question is a Burnham Revolution, notorious for various cryptic failures. We were discussing the inevitable replacement option when he homed in on the primary loop pump motor again and realized it was locked up. It had everyone fooled as it was vibrating as if it was operable, but hot a Hades due to the frozen prop shaft. This gig would probably have summed up @$600 but for the tricky diagnosis and my loquacious tendencies. At least I know who to call when I'm ready for that replacement/expansion."

"Bob was awesome and it was a great experience overall. We had 2-3 days of work lined up, and Bob was punctual, communicated well and did a solid job. Mother Nature didn’t cooperate with us when it came time to setup the lattice work under the deck, but it didn’t matter. Bob setup an outdoor awning to let him continue the job to through very rough conditions, without any complaints. After the job, I received an email with a list of future repairs that we talked about, so we have a record for a later date. I look forward to hiring Bob again soon. His pricing was fair and he was very upfront about it all."

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.
