What started out as a good experience with air Conditioning Engineers really took a strange twist.  Please read this in its entirety. 

My wife and I met with Bob Strang of Air Conditioning Engineers.  He was nice to deal with, no pressure and knowledgeable.    A rough estimate was given and he later came to the house to get a better assessment of the job and give a final estimate.  His prices were competitive, just a tad higher than our other quote, yet we felt more at ease with him. 

The technicians, Tom and Dan arrived as scheduled and were very professional and nice to deal with.  (Unlike the obnoxious a** sent here a number of years ago from Williams Heating and Cooling.)   Unfortunately, the techs were unable to run the chimney liner required for our water heater.  They certainly tried, yet either some mortar or the bend in the flue prevented them from pulling it through.  OK I understand that problems occur.  This item was originally overlooked in their price estimate so I explicitly recall that our estimate was increased by $400 for liner installation.  I relayed this information to the techs and they reduced the balance due by $400.  Makes sense, they were unable to provide the service prescribed.   I was advised and provided a name of a contractor who only did chimney liners and was more proficient.  So far, a setback, yet not really their fault.

The following day Bob from Air Conditioning Engineers called.  He asked what I was going to do next about the chimney liner.   He also informed me that his guys wasted an hour trying to install the liner and that the liner was damaged during this process.  He then informed me that this problem cost him $400 and asked if I would help pay for half!  I was caught off guard and told him I?d think about it as I actually considered it!   I checked with an instructor who teaches HVAC at MCC.  His rule of thumb for conducting business - he would not have even considered charging for an attempt, only for completed work.   That?s why one hires as contractor!  If a guide was used to pull the liner it would not have been damaged.  The damaged end could be shortened and reused.  The cost for this part is approx. $110 without any contractor discount.  I don?t see how they can claim a $400 cost and am not liable for their problems.

To make matters worse, I found that the technicians broke off three of the brackets required for securing my chimney cap.  I suppose they didn?t understand what they were for as the cap was removed, due to storm damage.   Once again, under normal circumstances I?d call and have them repair it.  I won?t call as I don?t need to be hounded for more money.  My choices now are to install 3 separate matching caps and install them myself ($30 -35 each at Home Depot)  or fabricate the 3 brackets and reinstall my custom cap (approx. $30 total material but more labor and more trips up and down the roof of my two story home).   I did relay this information on the customer satisfaction form and it went ignored.  The whole money issue really seemed strange and enough for me to take my business elsewhere.  If any warranty maintenance or repairs are required in the future, I am concerned this could have a negative impact.

It gets worse; later, when we turned on the furnace I noticed condensate dripping on the floor and stains on the exhaust pipe.  2 of the joints were not glued.  Along with the moisture I?m sure a certain amount of Carbon Monoxide gas was leaking into my home, a very dangerous situation.  I did disassemble and glue the exhaust properly.    Also the condensate drain causes puddling of water around my drain.   I?ll add an elbow and make a hole to accept it in the drain cover at a later date.

UPDATE - Bob and I have seemed to have worked out any differences.  He went out of his way to do so.  He's such a likable cuss what can I say!  Bottom line is always, would you do repeat business and my answer is yes.

"Because we had to coordinate the service call with a temporary shut-off, of the water, by the city timing was important. Mr. Hairston and his apprentice Gary arrived within approximately 15 minutes of our calling them, once the shut-off had occurred. They explained to us what work would be done and took approximately 35 minutes to complete the job. Before completing the work we were told that it was 'ok' to call to have the water restored. That meant that we were able to spend less time waiting for the city to come back out. As we had read in other reviews before, the area worked in was cleaned at the completion of the job. Mr. Hairston offered to send our receipt via email and was willing to accept whatever form of payment we wanted ( cash, check or charge). He invited us to contact him if anything else needed addressing. He was pleasant and polite as was Gary his apprentice.

"New special order unit came in very quickly, and installation was scheduled for the next day. Old unit was removed and hauled away. New unit was professionally installed with attention to detail not present on the old unit. No damage to walls or floors, and installers used extra measures to prevent outside dirt, snow, and water from being tracked into the house. Very happy with the entire purchase/installation experience."

"Installers were prompt, professional. They took care, using drop cloths inside to avoid tracking dirt.
The system did not work properly when initially installed, so the following Monday, a repair technician came and performed diagnosis and trouble shooting, in contact with manufacturer's rep. He was able to correct the problem and got the system operating.
In addition, to address my concerns that the condenser unit might have been damaged, they subsequently replaced that part of the system to ensure reliability.
I was very happy with their responsiveness to my concerns.
I will use this company again.

"The repair person, Keith, came a couple weeks ago and had to order the defroster for the refrigerator.  The part was delayed coming but the technician came back once (without charge) just to manually thaw out the coils so the refrigerator would continue to cool properly.  The part was installed today and the refrigerator runs great.  He explained what was going on, exactly what it would cost, and tried to keep me informed as to the part's arrival and installation.  I would definitely recommend their services!

"I was really surprised how smoothly the whole process was. Workers were very professional. On time everyday and cleaned up at the end of each day. Now, I just sit back and enjoy the kitchen I've always dreamed of."

"Started with home energy audit that cost only $59. Sales / tech person was very professional. Performed an energy audit that took HOURS. it was not a rushed job, and he reviewed his assessment with me in detail. That alone was worth the cost. He pointed out spots where there were big heat losses in my home, and what could be done to resolve them. Never pressured me to get the services, but he did show me which things I could do and how much they'd cost, as well as the rebate I'd receive from my energy company. I selected to get my basement rim joist spray insulated, add insulation to the attic, add insulation caps to all the recessed lighting fixtures in the attic, add insulation do attic entryway, and spray and install more insulation around the bonus room above my garage. Each one was an option, and gave improvements to the overall comfort of the house. Work was done in 2 days (they needed to come back due to power issues for the insulation blower). Overall, I'm happy with the results. house is more comfortable and furnace is running less."

"They were very knowledgeable and thorough. Did a great job, so we asked them to come back to do some recommended work (replacing corroded valves, etc.). May need to replace our boiler in the future, but they added what I think will be years of life to our current boiler. If we ever replace our boiler, we will have them do the work.
