"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"

Customers say: True professional

"We recently remodeled our bathroom with McCormick, and it was a fantastic experience. Khaled was informative, patient, and genuinely helpful, guiding us through choices for a perfect design. The team’s professionalism showed in their punctuality and quality. Every aspect was done with care, from tile placement to lighting. The transformation is truly impressive; the bathroom now feels open and luxurious. We’re beyond pleased with the result and look forward to more projects with them."

"Caccia ran into an unexpected underground obstacle while replacing our sewer lateral. They set up a temporary sewer line so we could use our home while they used additional labor and equipment to complete the project. Caccia honored the original quote amount with no upcharges for the extra work required. Caccia handles contingencies well. We have used them in the past and we will use them in the future."

"I've had Octavio do full bath plumbing for me. New copper pipes and finish fixtures with white glove installation. He is very knowledgeable and professional. Everything Octavio performs is with a great attention to detail. His professionalism is appreciated when it comes to reliability and cost. Worth every penny, if you want something done the right way the first time. Octavio is always my go-to guy when it comes to ANY plumbing needs."

Septic Tanks FAQs, answered by experts

There are a few things that can make your drain field fail. These include driving or parking vehicles or heavy machinery on the field, excess sodium in the soil, or having a high water table. You can prevent failure by ensuring your installer checks that your chosen location is suitable for a drain field and properly maintaining your system with the help of a professional.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

Although cesspits may be necessary depending on your main sewage system access or nearby soil quality, they carry a few drawbacks. Cesspools require regular emptying and have relatively high maintenance and pumping costs. Certain areas also disallow the use of cesspools and may require you to cover the cost of existing cesspools to be converted into septic tanks.

You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.
