Our gas central heater failed in late December 2010, on New Year's Eve. Since this was during a cold snap and since we had an elderly relative staying with us, I didn't delay things by getting competing bids (this was before I joined Angie's List) but rather called ARS, which had replaced a water heater for us a few years earlier.
Doug Snyder, from ARS, arrived on Monday, January 3 to diagnose the system. Using a miniature camera that he had snaked into the innards of the furnace, Doug showed me that the heat exchanger was cracked due to rust. It was determined that air conditioner coils, which were installed by Sears many years earlier, were improperly installed and caused condensation to drip onto the internal parts of the furnace instead of being drained out. There was rust, corrosion, and rusted-out spots throughout the furnace and blower unit. The condensation had also dripped into the electrostatic air cleaner that Sears had installed at the same time as the air conditioner and which had failed a year or two earlier. The furnace and air cleaner (if we wanted a replacement) would have to be replaced. Also, although the furnace and air conditioner complied with building codes when it was installed ten years earlier, replacing the furnace meant that the HVAC system would have to be brought up to current code (for example, the exhaust pipe for the heater could no longer be tied into the exhaust pipe for the gas water heater, but would need its own separate pipe to the outside). As a result of this, the entire HVAC system would have to be replaced, a Title 24 duct leakage test would have to be performed, and a City inspection would have to be performed.
Doug laid out the various replacement/repair options open to us. We chose a 60,000 BTU Rheem gas furnace, a 2.5 ton Rheem air conditioner condenser and evaporator coil, and an integrated electrostatic air cleaner. The system came with a 3-year labor, 10-year parts and compressor, and lifetime heat exchanger warranty. Parts and labor for removing the old system and installing the new HVAC system was about $12,650. The electrostatic air cleaner added about $1,200. The Title 24 compliance inspection (performed by a third-party) was about $975. Doug subtracted 10% (about $1,200) previous customer discount, for a total price of $13,592. Doug did try to get us to purchase some additional options, but we declined. Installation was scheduled for 2 days later, Wednesday, January 5, and I was told the installation would be performed in one day.
Installation went smoothly. Two ARS technicians (I did not write down their names) arrived, removed the old HVAC system, and installed the new system. This included drilling a hole through the wall of our stucco, frame house to accommodate the separate furnace vent pipe that I mentioned above and installing a condensation pump (the Sears installation relied on gravity). It was a long day, but they completed the removal and new installation of the new HVAC system and tested it by day's end as promised, and we had heat again. And they swept up after themselves. The technicians were very polite and took the time to explain to me what they were doing.
The Title 24 Compliance test (a duct leakage test) was performed on February 27 by a third-party company, Quality Verification Services, which has no affiliation with ARS. Our system passed the test on the first try.
In late summer of 2011, about 8 months after ARS installed our central HVAC system, a problem developed in the air conditioner condenser (the part of the AC that is located outdoors. When the AC finished cooling the house, the furnace blower and the compressor fan would shut off, but a loud humming/buzzing noise kept coming from the outside compressor. This happened intermittently; sometimes it would not happen at all, sometimes it would stop after a few minutes, and sometimes it would persist until the next time that the AC started. I called ARS to have a technician come out.
During the time between the installation of the HVAC and this problem, I had joined Angie's List. I looked up ARS, and was not entirely pleased with what I read. Some people gave ARS an "A" rating, others gave ARS a "D" or and "F" rating. I read all the reviews, especially the "D's" and "F's," and prepared myself for a fight with ARS.
I called ARS on a Thursday morning to schedule a technician, fully expecting to be put off for a week or two (my previous experiences with Sears home repair always resulted in delays of 10-14 days to arrive). I was told that a technician could come in an hour. I wasn't ready for that and asked if the appointment could be made for the next day in the afternoon. The service call was scheduled for between noon and 2PM the next day (Friday). On Friday, I prepared my self for the technician to show up late. Lance arrived at 12:05PM.
I described the problem to Lance, and attempted to demonstrate the intermittent problem to him. The compressor ran fine. Lance removed the cover from the compressor and we tried repeatedly to get it to fail. After about an hour, we were ready to give up, but decided to do one last test. The compressor failed: The fan turned off but a loud humming continued. Lance determined that a contactor -- a relay used to turn the compressor on and off -- had broken contacts and replaced it. Total charge for the service call was $0 since the unit was still under warranty.
As some other Angie's List members have reported, Lance did try to sell me some add-ons at the end: locking refrigerant connector caps (he said teenagers have been known to breathe the refrigerant to get high -- maybe true, maybe not) for $130; an automatic louver to fit on top of the compressor unit for $275; and an air purification system for $1,450. I declined, and that was that -- no pressure.
All in all, I am very pleased with the service from ARS. I expected the worst, but received the best service from them of all the repair services that I have used. All the ARS people with whom I dealt were very professional and competent. Their prices may be a tiny bit on the high side (that's why I gave them a B for price), but they deliver excellent service; and the B for quality was for the malfunction during the warranty period, but this was more likely the fault of Rheem manufacturing than ARS. Yes, I'd use them again.
