"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."

"Mike and his crew showed right on time. They took the time to understand my problem. They suggested ways to fix things and laid out a plan to get it done. They started right away and did a great job for me. I hope to use his services on other jobs around the house."

Heating and Air Conditioning questions, answered by experts

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.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.
