Lied to me. The installer smeared what looks like liquid nails across my wood paneling which if it was wiped off immediately would not have become an issue. They then told me that they do not do that kind of work to get it off the paneling. It took months of fighting on the phone to finally just get a partial refund to try and fix the issue. read more

From the initial sales visit by Melinda, to the completion of the installation of my new HVAC system, Warren Heating and Cooling was a very professional and friendly group to deal with. Melinda provided a well written, easy to understand quote, far better than any of the other 3 quotes I received. The price was also very competitive and fair. I was especially pleased that they prioritized my install because my AC was completely down. Brett, Mike and Jake did an excellent job installing the system. They arrived on time and worked hard all day, completing the install by the end of the day as promised. I so happy I choose Warren Heating and Cooling! Thanks. read more

Installation seemed to go well but when the unit completely failed, Warren Heating & Cooling did little to try to remedy the matter.

Warren heating and cooling were very professional, experienced and reliable. We used them two years ago for our downstairs air conditioning and we were very satisfied so we called them back to do our upstairs unit. They covered our floors and cleaned up everything. Everything came in earlier than expected and they got the job done in one day. I would highly recommend them! Dave Miller read more

I was able to switch from oil to gas thanks to a new gas line on my street. I got a couple of estimates but Warren Heating and Cooling was by far the best. Their representative Malinda was professional, knowledgeable. She answered all my questions and explained the whole process from start to finish. There team came yesterday and replaced the old oil burner with a 95% efficient gas boiler, all in one day. Mike and his team were amazing. I recommend these folks without reservation. You won't be disappointed. read more

Rich is the most sincere, reliable workman anyone would be privileged to hire. No job escapes him. Others could not figure out the problem, but it was something Rich would not give up on. He and his Son are compassionate experienced workers who really know what they are doing. read more

All around great experience with everyone at Warren Heating and Cooling replacing our geothermal system.

I agree with Jose review these guys never told us tune up parts are 200$ They don't stock them , got there permits wrong for install, thankfully I work for a gas company and was able to get gas turned on , installer asked to use my bathroom and blew the whole house out If he new it was going to be bad should have went down the road, will not use them again for installation. Some of the work they butchered! read more

We were first time users and the service was excellent. The tech Hilmi was very knowledgeable and patient and answer all our questions. We would highly recommend Warren Heating & Cooling for your next job. I would definitely use them again (but praying I don't have too lol)! read more

We had a split HVAC installed recently. The crew arrived promptly and were courteous and professional. Alll services that were described and promised to us were delivered in a timely manner. We would highly recommend Warren Heating and Cooling. read more

My central A/C was frequently blowing fuses. The guys arrived on time, had all the parts they needed, and had me up and running in short order. Can't ask for much better service than that! It's about a 35 year old unit, so fingers crossed it holds up. Good job ! read more

I spend a lot of my time writing about what I know best. Food! The preparation and the eating. What I spend little time on is borderline criminal. The people and companies that keep my family and me comfortable in our castle. I'll remedy that now. Some years ago, my parents told me they had secured the services of a new AC/Heating contractor. They urged me to give them a try. So I did and the rest is history. Paul and the folks at Warren are first rate. Phone calls are returned promptly. Service appointments are a snap to make and problems are id'd promptly and professionally. When my AC went on the fritz one July 4th, my emergency call was returned and I was talked through a reboot/fix. Turns out it was something I could do myself. Other companies out there would not have returned the call until the next business day. If you can't tell, I'm a fan. We appreciate you guys very much. read more

I had Warren Heating & Cooling install a new air conditioning unit in the heat of July. Those guys worked their tails off and came down from my attic sweaty but always polite and professional. Scott, the guy who did our estimate and set everything up, was awesome and most importantly, my dog liked him. These guys also beat out two other estimates I had from the area. They left everything in pristine condition, walked me through everything they did and how to run everything on the new system. The new unit has been working for over a week now and I am very happy with their work. I absolutely recommend Warren Heating & Cooling and will be using them every year for maintenance. read more

Here's a copy of the email I sent them after they installed 3 new units at my house. After sending the email they said they'd call me back but a week or so later I had to call them to get them to move. I wanted to see if someone can come out and look at the first floor unit. I don't think anything series is wrong but when it's on a noise is coming through the vents. When I first heard it I though the vacuum was on but soon realized it was the AC. When standing by the unit in the basement it sounds okay but when standing upstairs by the air vents it's loud enough that it's annoying and much louder than the old unit that was replaced. I wasn't going to say anything but while I'm complaining a few observations about the work: 1) Not sure of the right terminology but the sleeves/transition connecting the air conditioning units to the ductwork in the house looks rough. After I had the upstairs units replaced four years ago by a low budget installer he had a similar taped-up sheet metal workaround and the Warren guy servicing the units a few years later commented on the crappy job that was done. Well quite frankly I don't see much of an improvement with the new units. Whenever tape is used it's a sign of a short cut. One of the other company's that gave me a bid (that was slightly less) said they custom made their own sleeves and it wouldn't look anything like the low budget one I had. 2) I was disappointed no one didn't mention that I would need to close the permits and get final inspections done. 3) The electrical inspector pointed out that the conduit holding the electrical wires on two of the units were not secured with C clips within the first foot of the on/off switch. He pointed out that the first level unit was a particular issue as it wasn't secured at all until a flimsy plastic strap near the ceiling. He said he wasn't going to fail the inspection but suggested I fix them. I did so myself. 4) When cleaning up debris outside by the condensers I found a plastic cap on the ground that looks like it goes to the 410a serving fittings. When I went to see if one was missing I noted that the middle units (upstairs) was missing both caps while the other units have red metal caps. 5) I guess dirt was needed to seat the condenser pads. Was a bit disappointed that it came out of my kids' bicycle jump. I first indirectly used Warren when the contractor remodeling our basement subcontracted with Warren to relocate some ductwork. I thought the work was good and we were particularly pleased after engaging Warren to do the annual maintenance on the AC thereafter. In the process of getting our units replaced I had some others that were highly recommended but stuck with Warren given the positive experience. While I'm not ready to call it a mistake there's been a few disappointments in the recent install. read more

At first, I though the company was going to be fantastic. They came highly recommended by a family friend. upon having a rep come for an estimate, I felt assured the job would be done well. However, throughout the course of our project, they have become more and more unfriendly and difficult to work with. They have refused to send someone out to initially start our newly installed unit, told us we were not a priority, and have not sent someone in over a week to fix a vent which failed inspection. The field reps are not the issue. The Customer Services leaves much to be desired. read more

I called to make an appointment for an estimate for a commercial HVAC unit . The person on the phone was rude-- acted like I was bothering her. She took down all my information and then gave me an appointment between 9am-10am. I tried to have her give me a committed time as I am not able to sit idle for an hour to wait (and we all know an hour turns into two). Her response was "we dont do that". Excuse me- this was potentially a $10,000 job with the potential for much more business as I run several commercial shopping centers. There are plenty of people looking for work-- not going to deal with someone thats not only treating me like I just interrupted her coffee break-- but to refuse to work with me on a time., Thanks but no thanks read more

I got a flyer from Warren heating and cooling for fall maintenance, so I called them to service my two boilers. I was told that they would be out in 4 weeks. Since all was running fine I was ok with that. When the technician finally came he walked in and said he couldn't do anything because he needs parts for the service. He took down the model and serial number (something I could have easily done weeks before ) and told me I would hear back the next day. I didn't hear back so I called and they told me that my boiler was very old and hard to get parts for. (10 year old model that is still sold today) I went on line and found parts right away. I called back to tell them I had the parts and they told me they couldn't find parts for my other boiler now. When I asked if they would get to servicing the boilers before the end of the winter the woman said of course they would and told me she would have an answer for when they could do it in a bit. She called back about an hour later to tell me they cannot do the job. These guys are just looking to sell new equipment for outrageous prices. Stay away from these guys. read more

We looked at several contractors to replace our old ac and furnace, and these guys were not only less expensive, but more credible in their estimate of ac sizing than the others. They were polite, clean, on time, and delivered a system that runs great. We had it installed about 16 months ago, so we have been through all seasons. Wwe also recommended them to a friend who also had a good installation. So far, so good! read more

Warren Heating and Cooling did a great job installing a new air conditioning unit. They installed the unit last May when we had a couple of hot days. It worked great all summer long - much better than the previous unit. The matched it perfectly to the new heating unit we had installed the previous December. They arrived on time with everything they need to get the job done within a few hours. They cleaned up after themselves and took away all of the trash. They were friendly (for plumbers) and professional. I would have them back if I needed more work. read more

We converted from oil to gas, and was satisfied with the work: however, a wire was not connected which resulted that our humidifier pump could not discharge the water from the catch basin resulting in an over-flow onto the floor. However, Paul had that problem taken cared of immediately. Ed read more

I have just have my old HVAC system replaced with a new high efficiency Carrier unit by Warren Heating and Cooling LLC. I was very pleasantly surprise with their performance.

I read lot of reviews, had lot of quotes from different contractors and finally decided to go with Warren Heating and Cooling LLC, Milford, NJ From the first phone call with Crystal to the installation everything went smooth as I needed. Ron and Chris makes a good team and they came to my house on time on both the days as I need to install two new systems ( HVAC). Scott who came initially was able to make me understand about the different systems and though few contractor tried selling me high efficiency furnace system for my Attic, Scott did not push me and suggested me the right systems for both the floor. Price was very competitive and reasonable and so was the installation. Ron and Chris did not move out of the house till they were satisfied themselves.

I have already recommended two of my friends. read more

Two winters ago a noreaster was approaching when our gas furnace stopped working. With the indoor and winter temperatures plunging, we called Warren Heating & Cooling.

I want to really say how great and professional that Warren Heating and Cooling has been. From meeting with Scott for the estimate and dealing almost non-stop with Dawn (who BTW is such an asset to your company) they made our transition from an oil burning household to a converted gas system so easy. It's such a pleasure to deal with a company that puts your needs first! I am so glad to be able to continue our relationship in the future! read more

Warren Heating & Cooling installs the new Air conditioner today at our home. Their price is very competitive, and service is also very good.

10/28/11 had new heating and AC units installed and so far pretty pleased. There was no pressure at all from their staff or sales unit. They were patient and did a full inspection of our units and really tried to help us understand what our issues were including all options available. All the staff has been friendly and easy to work with. Crew that did installation seemed efficient and neat. They cleaned up everything after the job as if they were never here. Still working with them on making sure paperwork is filed in order to receive necessary rebates and hope the units prove to be energy efficient and work properly. After time if things continue to go well I would definitely recommend them. read more
