"We lost our hot water late on a Friday.

On Saturday morning, he arrived bright and early and installed the new water heater and made all the necessary upgrades in compliance with current building codes. Trevor was thorough, professional, conscientious, and highly skilled--and the quality of his work, from the premium parts to the final fit and finish, is truly outstanding.

Having grown one HVAC & plumbing company into an Inc. 5000 business, we know what success looks like, and what happy customers sound like. Same Day is not your traditional, bought-and-sold HVAC outfit. Family owned and operated, we offer efficient solutions for your home with a practice that has been perfected over time.

"We recently had Same Day Heating and Air Conditioning come to our house to inspect our furnaces before turning the furnaces on during the cooler winter months and they discovered that both units had gas leaks. The system is 20 years old so it wasnâ t a complete surprise although we had hoped to put off replacing them for about 1-2 years. The technician/ inspector was knowledgeable, thorough and professional in showing us pictures of the worn, damaged furnaces (2). He explained the options for repairs and replacement as well as pricing considerations. In the end we decided to have them install 2 new furnaces and 2 new heat pumps to replace our old AC units. The installation was scheduled and completed within a short time frame and done with as little disruption to our home and family as possible. Efficient and neat in their work, I can happily recommend Same Day Heating and AC. I am very reassured knowing that my furnaces and heat pumps can effectively and safely heat and cool our home for our family. Peace of mind is priceless when it comes to protecting your family."

Furthermore, when we decided to pivot from original project plan, Mike was very receptive and easy to work with. Will definitely use Mike for future landscaping and paving needs!"

French Drains questions, answered by experts

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.

It might be possible to dissolve hair caught in a drain, but it’s usually not a good way to go about clearing the clog. Some sources mention that baking soda and vinegar can do the trick, but this won’t actually dissolve the hair. The hydrochloric acid in drain cleaners can dissolve the hair over time, but it will much more quickly destroy your plumbing pipes and leave you with bigger issues. The best way to remove hair is to do it manually with a drain snake or to have a plumber use an auger to pull clogs out.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.
