"I am a person of modest means; because of APM I was able to replace my heating system at a price I could afford. APM helped me choose the right appliance that I then ordered online to save money. Appliance did not come with a part I needed for my specific installation; they educated me about the part, I was able to do an internet search and obtained the item on Ebay for a steal. Service quality was top notch, easy to work with, great communication via email and phone, worked clean, very nice people. I feel very fortunate to have had this service experience and would highly recommend this company.

"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

"I have only good things to say about the good staff Patrick and James and Anthony and Jean in the office. The problem was with the Generac trickle charger for the battery which starts the generator when the power goes off. Patrick tracked the cause of the problem and Anthony fixed it in short order after a small delay in getting a new part. Jean in the office kept me informed and is very pleasant to deal with. This group all seem eager to please.

"He was on-time, but was frustrated that there was no parking due to all the snow.  He was going to cancel, but we were able to find him a spot.  Initially he seemed a little annoyed with the circumstances, but ended up being really nice and helpful.  He had never installed a microwave before, so he was going through the directions along with me, but we got it up.  He patched up a hole we had, then a few shelves.  We ended up getting along really well, and he was kind enough to split his time within two visits, since we didn't have one of the items that we initially thought we would have. 
Overall it was a really good experience.  It was a rocky start, but after we got over the parking situation, he was professional, and really helpful with everything we needed from his end.
We were very happy with their service, thank you!

Generator Install FAQs, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home.
