"The heat pump was installed and it looked good but was whistling badly. The McGinley son left without any promise of a resolution. Stupidly, I gave him a check for the balance. Next day I called ACIQ customer service and they wanted the phone number of the installer. So I asked Bill M. for his son's phone number, which I'd never had. Very strange, he wouldn't provide the number right away and said maybe after the weekend. Anyway he never provided it. So I stopped payment on the check. When Mr. McGinley realized he wasn't getting paid, he came up to investigate himself. I meet him and we figured out the problem, which we fixed with a piece of tape. I then gave Bill another check for the balance which he later cashed. Subsequently, I asked for the invoice which I needed to submit a rebate application to NHSaves. For weeks I've heard excuses and still have not received an invoice. That is not acceptable for a company listed as an Angi Pro."

"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

Heating and Air Conditioning questions, answered by experts

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.

Turning off your AC may temporarily stop your unit from leaking water unless the leak is from a thawing coil that continues to thaw after the system is shut off. Regardless, it helps to discontinue use of the unit if it has a leak in order to figure out what’s causing the issue.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
