"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."

"Ray was very responsive and professional since my first contact with him. He came out early the next day to diagnose my broken AC and walked me through the testing stages and explained what he was doing, how it works, and why. He tried several methods to get the system up and running but ultimately, we had to replace the old unit. Since we were in a 100 degree heatwave, Ray was mindful of our situation and came early the next day to install the new unit within an hour. Very fortunate to have a seasoned professional like Ray to help us amidst the heat and Covid. I would highly recommend him to anyone looking for central AC work."

Nest Installation FAQs, answered by experts

The safest ways to treat bed bugs are non-chemical, such as using diatomaceous earth, essential oils, and heat and cold treatments. Heat treatments are also one of the most effective methods because it kills bed bugs at all levels of life stages: eggs, nymphs, and adults. However, you still need to take precautions by removing items that can be susceptible to heat damage. You also need to remove plants and pets from your home during treatment.

One of the most widespread chemicals used for killing termites is Fipronil. It’s one of the most common insecticides used by termite exterminators to kill termites fast. However, it’s toxic and generally used in outdoor areas only. Popular brand names of termite killers include Taurus, Bifen, Termidor, and BioAdvanced. All insecticides have pros and cons: Some are safer around humans but don’t last as long. Some may kill nearby plants or have power odors. Some are designed for safe indoor bait stations but take much longer to work.

If you’ve experienced bed bugs more than once, the best way to get rid of them permanently is to hire a professional exterminator near you. Exterminators use powerful treatments that target all stages of the bed bug life cycle. In addition, you can seal cracks in floors or walls, wash fabrics in hot water, and vacuum regularly to prevent them from coming back.

Stink bugs don't build nests, but they do like to hang around out of sight. They typically hide in cracks, crevices, and tight spaces within buildings, especially during the colder months. They are often found in attics, crawl spaces, and along walls or ceilings. To find them, give these areas a detailed inspection, particularly around windows, doors, and vents.

Eliminate standing water, use mosquito-repellent plants, and maintain regular treatments for best results.
