"Don Lonski of Lawson Home Services came to our home to clean our dryer duct and the back of our dryer. My goodness he was absolutely wonderful. The last Teck that came refused to open the back of our dryer and clean the lint. He claimed it was not necessary to open the Flexible Vent Hose to remove all the line. After a few years our dryer was not very hot. Clothes were still damp. So, I just stopped using my dryer and hung everything on all the doors. I was afraid of a fire. Saved money on the electric bill; but I needed my dryer back. We want to tell you that Don Lonski checked everything and he said you must always remove the Flexible Vent Hose and clean in the back of the dryer. And it should be done once every year. Not only that Don Lonski went into our crawl space and found our metal duck work was improperly installed. Instead of using the metal the whole 20 feet, they used 15 feet of metal and used the Flexible Vent Hose at both ends and did a terrible job of taping as a result we had major leakage. Don Lonski said he will return when the office schedules him and he will do the job correctly. Don was very professional, ever so pleasant and extremely knowledgeable. Don Lonski really took his time to explain all the problems we had. We are so grateful that we ended up with a great guy. Please schedule Don Lonski to return to complete our job completely. Tom & Carol Haley"

"I think Patsy and his crew did a great job replacing the half of my deck that was not under roof in Milton, DE. That’s what the 2 key people onsite say, and it’s what I and others see in the pictures, 1 of which is attached. As this is a rental house, I’ll look soon, but they all say that the new deck is solid, safe, and looks great. Me and my rental agent say that Patsy is very easy to work with. Recommend that you contact him for work in the area. M.Smith - Milton DE & Baltimore MD."

"During this very cold winter, I wanted my HVAC system checked out, esp after the fan were frozen in place before being de-iced by me. The service person was great. He checked my system and was able to answer my questions. Thank you."

Heating and Air Conditioning questions, answered by experts

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

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.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
