"Monty does excellent work. I needed a window AC installed which involved some custom fitting and mounting. I have a sliding window from left to right instead of up and down so to do a clean install was more involved than a traditional up down sliding window. I believe Monty went above and beyond to make sure the work was quality and addressed all my concerns. He made sure the whole installation was well sealed off using generous amounts of silicone.I highly recommend him for any handyman work you might need accomplished."

"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."

"furnace was installed and works well. I repaired gap in drywall above furnace after installation. for $3800 I think they should have offered to repair the drywall or compensation for my work. George reached out to me about my concerns and offered to resolve the issues. I'm very pleased with the job and his customer service."

Nest Installation FAQs, answered by experts

A temperature of 131 degrees Fahrenheit for 72 minutes will kill bed bugs. Research suggests several different ranges, but many suggest starting at 120 degrees Fahrenheit and maintaining that heat for at least two hours. Steam cleaning is an exception because steam comes so hot it can quickly kill bed bugs and their eggs, making it a good option for fast extermination.

DIY treatments exist, but professional extermination is recommended for thorough elimination and prevention.

Fleas thrive during the warmer months, starting in March and running through November. However, the prevalence of these pests depends on the climate in your state. That’s why it’s important to stay vigilant for fleas on your pets and property during spring, summer, and fall. Be sure to apply flea prevention sprays and medications to their coats as directed by a veterinarian.

Roaches have a strong sense of smell and are repelled by a variety of potent aromas. Scents that can help deter them include citrus (such as lemon and orange), herbs like peppermint, mint, basil, thyme, and oregano, spices like bay leaves, cinnamon, clove, and garlic, as well as lavender, eucalyptus, citronella, tea tree oil, and vinegar.

You can use these scents in several ways to create an unwelcoming environment for roaches:

  • Plants: Place mint or lavender plants in your home or garden.

  • Powders and Leaves: Sprinkle garlic powder or place crushed bay leaves and citrus peels in high-risk areas like kitchens, bathrooms, and entry points.

  • Sprays: Create a diluted solution with scents like lemon or vinegar to spray in your home. These can also be used in cleaning products or as room fresheners.

  • Essential Oils: While essential oils of these scents can be used, be cautious as they can be toxic to pets if inhaled.

It is important to note that while these smells can help keep roaches away, they typically do not kill them and may not be enough to drive out an existing infestation entirely. For best results, combine these scent-based deterrents with regular cleaning. Be sure to clean up all food spills, crumbs, and dirty dishes promptly, and keep trash cans covered with a tight-fitting lid to remove potential food sources.

Using rat poison in your crawl space can be risky. While it may kill rats, they can die in hard-to-reach places, causing foul odors and attracting other pests. Yikes. Moreover, secondary poisoning can happen to pets if they consume poisoned rats. If you decide to use poison, consult a local exterminator for guidance to ensure safety and effectiveness.
