"Updated bathroom electrical during remodeling. They came the day after I called them for an estimate for 1 hour of work and completed it immediately. Also gave me an estimate for a household generator. I would hire them again."

"After signing up with "Home Advisor" and selecting jp plumbing as a company i was interested in, JP sent me an email. I called an talked to Joy. She gave me the cost of replacing my old water heat. She gave me the cost right then and there. Said they could replace the heater the very next day. Joe called about 8 the next morning that he would be here asap. He came about 8:30, looked at the old heater and went to buy the replacement. He was back, carried the new heater downstairs, went right to work. Had everything in place in an hour. Carried the old water heater upstairs. Was efficient and clean. Good job, I will call them again. Elaine"

"Dillon was a great guy and worked fast and efficient. My house is 50 plus years old and the duct work had never been cleaned. Post the work, the house even smelled better. I am in the middle of a complete remodel and living in the house. I had all 11 vent grilles removed -(saved Dillon a pile of time not having to remove and re-install) and I would have thought a discount would have been in order."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

Heating and Air Conditioning FAQs, answered by experts

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.
