"The original (2002 construction) air-conditioning equipment was cycling on and off too frequently. Dynatemp checked the hvac systems and determined the correct replacement equipment needed to service the square footage of our townhouse. They gave us a detailed written estimate for the purchase and installation. Dynatemp offered several dates for the installation. They got the town permits needed for a crane, arrived before the crane, checked that the sidewalks were properly taped off, and prepared the old units for removal. They changed the underlying pads and installed the new units on the roof and then installed the new condenser coils. (The furnaces did not need to be replaced at this time but they made sure that the new units would work with the current and any future equipment.) They installed new thermostats better matched to the new equipment. They did not program the thermostats for us (for our security) but did explain how to do it. They left the manuals with us also. This project involved quite a few workers from 8am to around 6pm before they were completely done. The next day we smelled gas near the new condenser coil in the garage unit so we called Dynatemp. They sent an installer even though it was late afternoon Friday. He tested all the connections and found a small leak in one of the hose attachments which he was able to fix it quickly. He then rechecked the unit. We were very relieved and grateful that he came right away.

"It went very well.  Tony is very responsive, courteous, and goes out of his way to make things convenient for the customer.  Not only is he very competent and thorough in his work, but he also  did a lot of the leg work, picking things up at the electric supply store, returned a couple things that I had incorrectly purchased there in my own trips prior to hiring him, and even went there on my behalf for a bed lamp that needed a new contact.  He disconnected it, brought it to the store, took a trip back to the store a week later to pick it up, and reinstalled it for me.  Tony could have applied a trip charge for each of the many visits he made to my place but didn't.  He also took the time to explain options, solutions, and even gave me a bit of free schooling in electrical work.  I highly recommend him and his business.

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.
