Additional address - 20 Petra Lane, Sec 6, Albany, NY 12205. Additional phones - (518) 456-9376.

"I rented for seven years. It was a constant nightmare. No pest control, maintenance requests are just ignored or months late, rent hikes are constant. Total scum lords. Rent hikes costed me $700 monthly ($100 more each year) Told me to pay for my own pest control for the rodents and roaches at this property and won’t pay me back (totally breaks the law and doesn’t care) Using rent fixing as well. Run for the hills, hopefully these terrible deplorable peoples will shut their doors soon."

"We bought a boiler from Fox Air, they also installed it. The boiler had to be removed and stored while the house underwent construction. Fox Air removed it, stored it, and happily charged us for this removal and storage. Then the company was sold and the new owners are not honoring the commitment to reinstall and warrantee the work and boiler. They want "nothing to do with this thing." Meanwhile, the storage was not done correctly and many of the pats have seized or rusted. Again, this is all while happily taking storage fees. The costs to undo Fox Airs duplicity and fraud are now exceeding 2500$. We used to be incredibly impressed with the honor, integrity, and quality of Fox AIr’s work. No longer."

Energy Efficiency Auditing questions, answered by experts

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home.
