Dennis arrived EXACTLY at 7:00AM, as promised--courteous, professional. I had been quite neglectful and had not even replaced my furnace filter in some time. He showed me how to replace the filter, he talked with me about potential issues with improper maintenance- totally non-judgmental--he pointed out a branch that was interfering with my a/c, and suggested I hose it down occasionally (I have 2 large dogs, and the unit was a bit clogged with dog hair). He was thorough, and polite. He told me of their maintenance plan, that if I forget to call them, they will call me--no pressure--no sales, just good information--and YES, I will enroll in their maintenance plan. I felt I could trust him and will ask that he continue to service my account.
Description of Work: Maintenance check on furnace, replace filter. Maintenance check on a/c.

The price and product and installation went well and I am very happy with the performance of the furnace. However, there were numerous issues that left me with a poor impression around how organized they are. I negotiated my final installation, but never received an updated proposal. The installer arrived 30 minutes early, which could be positive, except it was 7:00 a.m and I was still in the shower. The details of my installation had not been communicated thoroughly to him by the sales person, so I had to stay on top of things. He didn't even know about the humidifier and had to leave to get one. I reminded him about a duct he was supposed to close. Even after that, he almost left without it done. After he left, I continued to find things laying around that I had to call the company about. The owner came out to check everything out, which was very positive, but I continued to find things after he left. There were things in an adjacent room on a chair, on a table, on a shelf in the furnace room. It was very odd. Then it turns out my manufacturer rebate request was never put through. They were very responsive to my calls and questions, so this could have been a very positive experience if they just got their act together. I just have never had to make so many follow up calls about anything in the past. A couple of months later I had them come out to check out my air conditioning. The compressor was shot. The technician told me the cost of the compressor was 70% of the cost of a new system. It was summer and I thought they would call me very quickly to discuss a repair or replacement. I didn't hear from them for 2 days about the cost of repair (which turned out to only be 30% of a new furnace) and then received a call a week later to see if I had interest in discussing replacement. I made other arrangements.

This was a huge job that required a pipefitter that really knew his stuff. I'd hired Alan for other jobs and learned that, although they weren't always the low bid on a project, his guys did excellent work. They started and finished when they said they would. I like working with Alan because he does a good job explaining what is needed, why, and how it works. He was willing to reuse any equipment that was serviceable to reduce the project cost. He makes reasonable suggestions for the best outcome and is willing to listen to my concerns and ideas about the project.
Description of Work: Install new boiler with new pumps and indirect water heater. The project also included adding two more zones, installing some radiators in new areas as well as a general clean-up of a piping nightmare in the boiler room. The piping was re-designed to allow greater ease for servicing in the future and to allow more space for my workshop, which is also in the boiler room.

They did a GREAT job and their service guy was very personable and helpful. I will use them again. A bit more expensive than I thought, but it was because our tank was so old and had not been drained in so long that it took forever.
Description of Work: They came in and tested the boiler for CO emissions, along with giving it a tune up. Drained the holding tank, and re-sealed the system. Also taught me how to bleed the radiators.

I called the top 5 companies for estimates from Angie s List so I originally did not know what products they install. During this process I had estimates from companies that represent 3 manufactures. After learning about these 3 companies, I decided that Carrier was the best one for me and I chose Gross Heating because of the salesperson's knowledge and competitive price compared to the other Carrier dealer.

The crew was on time & polite. The various trades and trucks came and went all day long with precision. Excellent project management on this job. Everything was installed straight & professionally. No mess or garbage was left behind. A few times I interrupted the installers to do something a little different than it looked like they were going to do, and they switched their plan without blinking an eye. It took me about two weeks to decide what options I wanted to install with my system. I went through 10 different combinations with Greg Billmyer, my sales contact. As I mixed and matched, the prices never changed, or got all mixed up, and buried in the confusion of it all. Any other time I have done this, I would always get the "well, the prices are not correct anymore because of this or that or whatever reason". Greg was fair, honest and stood behind his original pricing that he gave me at the kitchen table in my house.
Description of Work: Over the years my A/C & furnace have been replaced at different times, with differing brands, and decided to replace then both as a matched system at this time. After researching the Carrier & Lennox brands, I decided on Carrier. I thought the Lennox would be too expensive, due to the fact that most contractors seem to be Carrier. I received other quotes from Carrier dealers, but Gross was the only Carrier Dealer that informed me I might be better off to stick with a Lennox System, because my particular furnace was still under a special, free replacement, extended warranty that their is no way I would have ever known about. He quoted the Lennox A/C & Furnace System, as well as an Aprilaire unit, touch screen control (free due to the Angie's List coupon), duct work, electrical work, and a 400 cfm in-line duct booster fan for a remote bedroom that was always cold or hot in the wrong season. Because the furnace was now free, the price was thousands less than the others.

I got 3 estimates; Gross gave me the best price and answered all my questions directly (without a sales pitch). They showed up on time (there were 3 guys -- one showed up first, the other followed a bit later, and the last guy showed towards the end, I suspect to do the electrical work). They completed the work in a reasonable amount of time. After they completed the installation, I was told that the city would need to come by to inspect and approve the installation, so that was an additional appointment I had to make that I was not expecting (this info was not provided by any of the companies at the estimate stage). Overall, no complaints. Everything went well.

It went as well as we could have hoped. Greg the sales rep was very friendly, organized and easy to work with. He provided us with many cost saving options, educated us and never pushed us. We got five estimates total and Gross was the among the highest, but rebates brought the total cost in line with other vendors. Mike and Jeff did an excellent installation job. They worked around our requests when installing the new duct. They were also friendly and clean (a very pleasant surprise). Greg returned upon installation to walk us through the new system and was receptive to and patient with our questions. Overall, it was more money, but it was absolutely worth it. The experience was outstanding and we'll have a solid system for years.

The technician arrived promptly as scheduled at 7:30 am and proceeded to get right to work. He was pleasant, although he never introduced himself or asked for my name. He found that the Mercury sensor in our boiler was about to go bad and offered to check if he had a replacement in his truck. He did and replaced that for us, in addition to finding a problem with the part that circulates the water. He was able to fix that part with out needing any replacement parts, which saved us a bundle. He was finished in less time than estimated, about an hour and left the place as clean as he found it.

Excellent. The technician repaired and replaced parts, showed all his work, pointed out other areas of concern, and generally performed better than my expectations. He even showed me parts of the furnace that another company (Blau) had said would need replacing for an exorbitant fee. He was not critical of other companies, but was very informative. Finally, he did some work for which we were not charged. The overall experience was exactly the kind of customer/company exchange I would consider exemplary.

I thought their service was great. Since I live in a condo and the old system was 30 years old the new system was more difficult to install. New lines had to be run between the outside unit and the inside air handler. Alan figured out a clever way to run the new lines almost invisibly inside a closet. In addition they installed the air handler further into the attic crawl space to dramatically reduce the noise of the unit. I couldn't be more pleased.

They were prompt and efficient. We had a quote from another contractor for over $3,000 which seemed excessive to us for adding some duct work and a cold air return. Their price was much more reasonable and more along the lines of what we were expecting. Their worker arrive promptly, was very personable and professional and work very hard all day! He stayed well past 5:00 p.m. to finish the job. He cleaned everything up and did a great job! When it is time to replace our 18 year old furnace, we will definitely be giving them a call!

They are extremely reliable, neat, and the workmen are responsible. They are always on time and if they are running late they will call to let you know. The sales people were very helpful when I upgraded my system. I have been using them for about 15 years and if you are a regular customer and your heating goes out they will put you on the top of the list.

Made appointment-had someone out in 2 days. During recent cold snap, furnace had been making a "funny" clunk - technician showed up, and unfortunately, condemned furnace because it was 15 years old. Went downstairs, looked at it, adjusted and replaced filter, and came back up and apologized for saying he didn't hold much hope for it based on its age. Said it was, in it's day, the top of the line Carrier high efficiency furnace, and it really seemed to be OK, with the exception of a pressure switch(s) that needed replacing. Clunk was bad humidifier. Made subsequent visit to replace humidifier and pressure switches. Dinged them one spot for professionalism, although he did redeem himself!

They were quite the friendly pair. They were able to tastefully joke around and get the job done fast. They made sure the new system worked properly before they left.
