At Paschal there is a single statement that we live by every day. “Professional People. Professional Service.” Being a professional is more than just earning a living through an occupation. Professionalism involves consistently achieving high standards, both visibly and “behind the scenes” – whatever your role or profession. Professionalism is a powerful quality. It allows you to fulfill your role to the best of your ability. It helps you to impress and inspire others. And it gives you a deep sense of satisfaction and self-worth. What’s more, professionalism is something that everyone can aspire to from day one of their career. A Paschal Professional gives 150% every day. They go above and beyond what needs to be done. They have pride & satisfaction in every project they tackle.

"Installed my elderly grandmother Norma's HVAC 6 years ago. Recently A coil was icing up. She was told she'd need a new A coil (not cleaning first). A-Coil was covered under 10 year warranty but not labor. They quoted her 2900 to install the new A-Coil. I checked with multiple other HVAC firms, and the labor to install this part and the refridgerant was on the order of 900-1000. This firm gouged my elderly grandmother. They didn't send her an itemized bill, so I think they just have a set price that includes the part. They took her money and there has been no effort by them to make this right. Watch out, they'll do this to you too or someone you love. They said it's inflation, but this is what happens when they sense that they can take advantage of someone. They won't talk to me (her grandson), only her, and told her there was nothing they could do and just took her money. Beware, use someone else, you cannot trust these people."

Recently called them out to install a new kitchen faucet that we had purchased (Moen faucet, purchased from Lowes), and the estimate was $895!!! That's an outrageous price! Instead, we did it ourselves - took 1 hour."

"Patrick Benigno came out today to give me an estimate for a new patio cover along with removal of the current cover. We went over what I wanted and expected of the new cover. I explained my expectations and what was a “must have.” The must have was guttering on the outside of the cover with gutter guards. We went outside so he could measure and determine what had to be done. He went over the product as well as the process. He was very thorough and I only had a couple of questions because he had already covered my main questions. We signed a contract the same day. I would highly recommend Four Seasons Home Products if you are interested in a patio cover."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
