I received a call from the owner, not to offer a better price but to find out what had happened and what they could do to improve going forward. The owner offered to come out and sit with me to hear how things went and how they could work with their team to improve the experience for others. I had contacted all of the national chains and couldn't bite the bullet for their $99/deal that locked me into a lengthy contract to proprietary equipment. I was pleasantly surprised with the fact that OSS called me and worked to make it right. I look forward to having them install my system and refer them to my friends, family and neighbors!

I have never had an issue with Cote Electric who serviced our generator for years. I missed the…read moreannouncement that they had become part of Heritage Home Services. I called Cote wondering why hadn't gotten by annual service contract renewal. They explained the change and told me about the Heritage Advantage Membership plan which provides discounts on repairs and purchases and discounts on maintenance. We signed up and had our first annual maintenance check since the change. Our service tech, Pharaoh, gave us a heads up that he was en-route, explained what he was going to do, how much it would cost and how long he expected it to take. He was very pleasant, completed the work promptly and cleanly. No complaints with the change to Heritage and will continue to use them for service.

Had a service agreement with COTE. Went fine the first year. Then, they were purchased by Heritage…read more Next year, no one calls. No reminder. No one comes out. I call to make an appointment and am told the price increased by over 50% (from $249 in March 2025 to $375 for March 2026). Is there a point to a service agreement if you still have to make an appointment and the price can increase by over 50% in one year? The answer is...nope. No point at all. So, I'm off to find a new service company. Here's some text from their contract (emphasis is mine): "Why should I sign up when I can just call each year for maintenance? If you call each year we will be glad to accommodate you and come and perform the PM for your generator. However, by not signing a contract you risk the possibility of a rate increase every year whereas A PM CUSTOMER IS GUARANTEED THE RATE FOR THE DURATION OF THE PM AGREEMENT (except for continuous maintenance which may be subject to rate increase). Also, PM customers are in our database and WILL NOT NEED TO CALL for PM service. A PM customer will also receive priority service, specifically when winter rolls around and we receive an increase in service calls. A PM customer will be charged a service rate of $105.00 per hr for any repairs needed, a non PM customer is charged $140.00 per hr" Note that they never called. And they immediately raised the rate. Can they do that? Yes, technically, because elsewhere they say this: "Labor will be at a rate of 80% of base rate, which is currently $140/hour and is subject to change without notice." So, yeah...they basically lie about the benefit of a service agreement and their agreement is entirely contradictory. I'd recommend you stay away from these guys. EDIT: They called me and told me that they had called to make an appointment and told me the date they called. I checked my phone (which is the number they told me they called) and my phone has no record of any call from them on that day. My text has no record of any text on that day. They also said that they had to raise their prices but offered me a comp service. I told them no thank you, as I found someone willing to do the service for very close to their old price. Therefore, I stand by my rating and review.

If you need fire monitoring for less than five years don't sign the contract and find another company. JM Protective utilizes a predatory 5 year, unassignable contract for alarm monitoring services, with an exorbitant early termination fee (90% of remainder)! We acquired a property in Manchester two years ago that was using JM Protective for fire alarm monitoring. All alarm monitoring equipment was already set up and on the premises. JM simply continued the existing monitoring that they were already doing for the previous owner. Upon recent sale of the building in early March 2018, we were surprised to find out that JM Protective pointed to fine print in the contract stating that 1) the contract was unassignable to the new owner and 2) We owed 90% of the remaining contract life, or an additional $2160 for services we would never receive. After many attempted phone calls and emails, both from the property management company and the property owner, we were finally able to speak to Joe Morrison, on 3/21/18. After some back and forth discussion, he indicated that he would review the contract and call back later that afternoon. We tried calling pretty much every day after, and believe we were hung up on several times. We also emailed him several times. He finally responded to an email basically stating that he would not reduce the charges. We have paid the final invoice by the due date as we believe this contract may be contractually enforceable. However, it's highly predatory and we want others to be aware of this tactic. Also check BBB for similar complaints
