"Technician (Ross) conducted troubleshooting and repair procedures to isolate the reason the Heat Pump was not cooling, and place unit back into operation. Determined defective part and replaced it immediately with part stocked in van. Checked refrigerant and determined that a loss had occurred. Checked inside temp at distribution and return vent.  Added R22 to the unit and retested. Concerned of a refrigerant loss, Ross used a detector and systematically checked the interior air handler and detected a leak in the coil.  He advised of options to consider, including replacement of the coil.  In coordination with the Wooldridge office, he determined the replacement cost of the coil, labor cost and estimated shipping time...if I plan to elect the coil replacement repair option.  For consideration of complete unit replacement he will defer to Wooldridge sales staff.  All work specifics and repair parts are case noted to expedite the repair process.  Ross was an excellent "teacher" and guided me through all of the troubleshooting processes and repair accomplished...giving me confidence in the work accomplished .  Absolutely Professional Technician.
I am monitoring the system and evaluating the course of action to take. 
Thank you Wooldridge Heating and Air  for your professional service and your absolutely timely (same day) response.

"The technician responded to a Sunday morning call to check on a lack of water coming into the house by arriving later that afternoon.  He then spent two hours testing the switch, guage and tank on the well.  When nothing conclusive was determined, he said he would return later in the week to measure the depth of the well, thinking that perhaps it had run out of water or that the pump wasn't low enough.  He returned on Thursday as scheduled, tested the water depth without pulling the pump, thereby saving me at least $700, and then found a problem in the toilet.  He addressed that and gave me some dye to use to test for further leaks in the toilet.  He suggested I put a low-water cut-off switch on the well pump and I agreed.  When he called later to schedule that job, I told him I had changed my mind, but he came by anyway to check on the toilet.  In all he spent about 6 hours at the house, talked me through each test he performed and made recommendations as to how to deal with the situation in the long term."

"The contractor was a true pro.,he new his product ,he new how important to size the heater needed to do the job correctly and he priced the install accordingly.He was prompt always on time,removed the old water heater and made necessary changes to my home to accommodate the new tankless heater.He installed a new unit that has a great reliability history and long term warranty at a fair cost.Not heard of in todayâ s business world and the man that owns the business is the person who actually does the work! I feel like I did hire a true PRO for my job and I would recommend him to anyone that would need his service in the future!"

"Issue: water backed up in laundry room floor and downstairs bathroom commode bubbling noise when two showers were running at the same time. Anthony performed a drain vision procedure determined the possible need to replace pipes due to age, the dirt settling, small roots, grease, soap, garbage disposal, etc. A second test by Jason via drain vision for further analysis. No obstruction however, determined narrowing could continue to be an issue over time. Both Anthony and Jason are very knowledgeable."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."
