"I had a whole-house generator installed by an electrical contractor. It was wired incorrectly. I made an appointment with Mr. Electric of Queensbury, NY. They diagnosed the issue, ordered the parts, and installed them in a reasonable time. This was not their problem, but they treated it like it was. I am very impressed with their professionalism. Their employee Brian treated our home like it was his. When he had to enter our home, he put covers on his boots so he wouldn't track mud and snow into our home. He gave us an ETA for when he would come to do the work and explained the billing. If I need any electrical work done in the future, it will be done by Mr. Electric of Queensbury, NY."

"Had a leak in the house while we were out of town. They were quick to show up. Then proceeded to disconnect the internet, cameras, security system and heating controls. Not a good thing to happen while you are away. They informed our neighbor the cost and that we would be billed. I told the neighbor that all the systems were disconnected. They told her it wasn’t them. I called the company and was told “they found an empty plug and didn’t unplug anything”. Days later I got someone to the house to reconnect what they had unplugged. After informing them of their mistake, I was told that my house was unsafe and they would have plugged it back in if I had asked them. Say wha?? Gaslight much? They also proceeded to bill my credit card the day of their visit. No apologies, no accountability, no professionalism, no courtesy, no nothing. Just Overpriced, Rude and dishonest. Avoid"

Heating and Air Conditioning questions, answered by experts

AC capacitors last between five and 15 years, with an average lifespan of 10 years. Most people only need to replace a capacitor once during an AC unit’s lifetime. You don’t need to replace the capacitor unless something is wrong with it, which an HVAC repair pro can diagnose. 

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.
