"Hats off to Kingdom Air!!! They called me to schedule a time to check my A/C before hot weather. Had an appointment today (5/19) between 1000 and 1200. Got a call it might be between 1400 and 1600 before they could get here because with the storm we had last night they had extra service calls. No problem, my A/C is working. At 1205 I had a knock on my door. Clay came in; spent approximately an hour and a half going over everything for/with me. Once again, hats off to Kingdom Air and CLAY!!"

I’ve worked as an electrical engineer for a few years and started my business in 2023. I quit my job in November of ‘25 and am working the business full time. I have five start ratings on Google and strive to maintain a good line of communication with my clients. Honesty and integrity are key in my world and I ensure that as a customer of Amped Up Home Solutions you will receive just that.

I’m a hardworking person who doesn’t like to leave projects half finished or looking sloppy, I can be a bit of a perfectionist. I’ve always fixed and built almost everything I needed myself and I take pride in being self sufficient. I’ve been an electrician for a year and half now and before that I was fabricating aerators for private residences. I have a wife and two children, so I can handle the chaos of a whole house remodel even if you decide to alter any details halfway through.

"I was very impressed with Rich throughout the entire process of working with him. He gave us the best price for the same appliances the other companies were going to install. Rich was the only one who actively followed up and answered all of my questions prior to hiring him. When we did hire him, he arrived on schedule and completed the job on schedule as well. I was very impressed with his professionalism. I would recommend Rich to anyone in the market for a new HVAC system. I will hire him again for maintenance and other HVAC needs."

"Super HVAC showed me what I needed to do to make my A/C more efficient.  Spent about 20 minutes at my house and refused payment for his time.  He said he did nothing and so he charged nothing.  I even stated that he spent time there, but he would not accept payment. 
What a wonderful attitude and one that will make me recommend them to anyone looking for HVAC.  I certainly will call them when I get ready to make any HVAC changes in the future.

Heating and Air Conditioning questions, answered by experts

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.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.
