"Jay was able to come early which worked for us. He assessed the problem with the leaking valve, offered 2 solutions with clear pricing and clear reasoning as to why he recommended the slightly more expensive one (much less likely to fail in the future!). He accomplished the work quickly, showed me the completed work, and showed me why the other valve had failed, AND the area was clean and dry when he was done. Throughout the visit he was pleasant, polite and respectful. Will be happy to use this company again!!!"

"This is NOT a trustworthy company. All major systems were working well. I had them out for their $19.99 check as I was getting ready to sell the property. The tech said my best and most viable option was to replace everything. After I showed him the permit history detailing that the hot water heater was only 4 years old and the ac unit was 6 years old (the furnace is older, but works well) he just shrugged his shoulders and repeated his same packaged answer "I'm not here to sell you anything, just advise. Your best option is to replace everything new." The appointment was a joke and waste of time and money."

Generator Install questions, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
