"My salesman was very knowledgeable and informative of the HVAC system being replaced. The installers, Kyle and Keshawn, were wonderful. Never had a better group of people. They were very thorough and went above and beyond what was expected. Great service all the way from ARS."

"HSP was fantastic and I highly recommend them. Cameron and DayDay were responsive, on-time, and well-priced. As they worked, they were efficient, thorough, and organized. They cleaned up and the work was very well done. They were also really kind to my kids. I will definitely be hiring them again."

"Nicolle has done painting, shelf installation, picture hanging, and all those little projects around the house for me. Every job has been done with so much care and attention to detail, and everything always looks perfect when she’s finished. My husband is handy, but sometimes I need someone who is extra precise and detail-oriented — especially for things like hanging shelves and artwork evenly or getting clean paint lines. She absolutely delivers every time. Professional, reliable, and meticulous. Highly recommend!"

"Under new Ownership! I have known the owners personally for 20+ years and can attest that they are amazingly generous, kind, and selfless people. Last month, the HVAC went out in one of my rental homes. I was out of town, and Excel flawlessly completed the project on time and without any complications. My tenants were completely satisfied with the level of professionalism they demonstrated, and I found their pricing to be very reasonable. I'm switching my HVAC company to Excel because of my inside knowledge of who the owners are and the high level of reliability and integrity the possess. You can't go wrong with Excel!"

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.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.
