"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

Generator Install questions, answered by experts

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.
