I called for a free estimate and Jeff Yaeger came over in a couple of days. Although the estimate was not the lowest we got (out of 3), Jeff's friendly demeanor and clear answers to questions, as well as giving us names of satisfied customers as referrals, tipped the balance toward Gross. The furnace was installed less than 2 weeks later, all in one day. We were amazed at how fast, clean, and quiet the workers were. Paul Yates was the team leader and instructed me on how to adjust the humidifier and change the filter (both yearly) and work the thermostat and aquastat. Subsequently we had a problem when VERY cold temps hit on a Sunday. Service call back was prompt and the repair person came within two hours (missing the Super Bowl as he did so!). We feel very satisfied and would recommend Gross to others. This furnace has enabled us to turn our thermostat down 2 degrees (68 day and 63 night) and still remain comfortable.
Description of Work: Removed antique furnace (1950's). Installed Carrier Infinity 96 (Energy Star) forced air gas furnace with humidifier and 4-inch filter. Attached cold air duct, new gas connections, PVC pipe vents to outside. Installed new digital thermostat and aquastat. Gave orientation to homeowner on proper use and maintenance of new system.

Called for service at 08:00 AM. Telephone representative was courteous. He said it would probably be after noon before they would arrive and they would call first. I received a call at 3:30 PM to let me know that the service man was on the way. Actual time of arrival was 4:00 PM. The service man was very grumpy. Complained about having a long day and about being sent to jobs that were far apart from each other. OK, I admit I was a little grumpy too after waiting all day with no heat. I was charged $168 for the ignition module. Later, I found the exact same ignition module on the Internet for $98. The labor charge was $91 for 45 minutes.
Description of Work: Replaced ignition module on Weill-McLain boiler.

Another company had looked it over, but couldn't seem to handle the fact that we had a very old boiler (turns out they were mostly in the replacement equipment business). Gross cleaned it up and gave it a clean bill of health (for such an old geezer). They also worked on the old boiler at our old house, again nursing it through its old age. We will be replacing Bessy within a couple of years, and will definitely look to Gross to do the work.
Description of Work: Ran a check on old Bessy (our 46-year-old boiler), so that we could get our house purchase cleared with lender.

They're great! Very personable, honest, on time, if not they call. They do a great job, and their prices are reasonable. One of their employees found a dead mouse (yuck) when cleaning my furnace, and got rid of it for me! Now that's service!
Description of Work: They cleaned and checked my A/C. I've also used them to do the same for my furnace.

We've been using Gross Heating for two years now. When we moved into our house the boiler hadn't been serviced for five years so the initial bill was over $300 but we've had them come every year and it runs like a top - it's worth the $95!!!

THE FEE SEEMED STANDARD FOR THE INDUSTRY. THE SERVICEMAN WAS INFORMATIVE WHEN I ASKED HIM QUESTIONS. HE DID OFFER TO PUT SOME TYPE OF COVER ON THE AC UNIT OUTDOORS TO REDUCE NOISE, AND AFTERWARDS I WISHED I''D ASKED HIM MORE QUESTIONS ABOUT THAT OPTION, BUT I DIDN''T THINK OF IT AND HE DIDN''T VOLUNTARILY EXPLAIN.
Description of Work: CHECKED OUT AC UNIT OUTDOORS AND IN BASEMENT TO DETERMINE IF ANYTHING WRONG, AS OUR NEIGHBORS HAVE COMPLAINED ABOUT THE NOISE IT MAKES. THE SERVICEMAN MADE NO ADJUSTMENTS, EXPLAINED THE NOISE WAS NOT EXCESSIVE.

DURING AN EXTREME HOT SPELL, MY A/C FAILED. THE PRESIDENT OF GROSS HEATING CAME OUT WITHIN 3 HOURS (AFTER ANOTHER HVAC COMPANY CAME OUT, BUT FAILED TO DELIVER A QUOTE FOR REPLACEMENT). HE OFFERED A REPLACEMENT QUOTE, BUT LOOKED AT THE UNIT AND DIAGNOSED THE PROBLEM AND SUGGESTED A FAN MOTOR COULD FIX THE UNIT AT A SUBSTANTIAL SAVINGS. THE SERVICE TECH WAS THERE THE NEXT DAY AND REPLACED THE FAN MOTOR AND FOUND A SLOW LEAK DUE TO A PREVIOUS POOR REPAIR. I HIGHLY RECOMMEND GROSS HEATING - THEY OFFERED SUPERIOR SERVICE AND PROFESSIONAL CARE.
Description of Work: REPAIRED A/C BLOWER FAN AND REPAIRED DAMAGED FREON FILLER TUBE.
