"Bob has done numerous projects for our old house over the years mainly carpentry, and most recently to replace cedar siding on a large area of the house. Bob does excellent carpentry and finish work and is an extremely hard worker. He has also done wood gutter repair, cleaning and sealing, hung exterior doors and installed exterior wood railings for us.

- Closely follow the average True Cost Rate furnished on the Homeowners section of Home Advisor for labor costs - Show up on time and give up front estimates - Focus on service work and limited multi-day projects so my schedule remains fluid - Advocate on the customer's behalf shopping for best prices on quality materials and best practices to get jobs done to code at the best rate possible

"We had an issue with a Dry Well periodically backing up. Damian and the D Day Plumbing team were very professional and knowledgeable and provided an estimate with a couple different options and their related costs. They installed a new utility sink, sink pump, and needed piping and valves with tie ins to the main septic. They made improvement above and beyond the initial job breakdown, all the while staying within budget. I will certainly consider them again for any future work. Thank you Damian and the D Day Plumbing Team for a job very done!"

What good is quality if it is not affordable? At Conger's Heating & Cooling, Inc., we specialize in all your heating and cooling needs. We are committed to delivering Home Heating Oil & HVAC installations at the lowest possible price to every customer in our community. Call today for your current oil price.

"Very prompt, knowledgeable, and professional individual. Shawn was the most thorough of all potential contractors in reviewing my replacement boiler situation, and was able to convince me that I did not need a larger boiler recommended by another contractor. He arrived and completed the job as scheduled, and his work was excellent. The piping is neatly arranged and marked should I need to isolate a heating zone, and he took the time to explain all fluid flows for the heating system. I could not be happier with using Shawn for the installation of a replacement oil burner and hot water tank."

Heating and Air Conditioning questions, answered by experts

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Zoned HVAC systems can be worth it for some homeowners, even with the added HVAC replacement costs, because they offer tremendous benefits. Zoned HVAC may offer greater stability and efficiency if your home has multiple levels and experiences constant temperature fluctuations. However, even smaller homes without major fluctuations can benefit since zoned HVAC systems can adjust their temperature more quickly by heating and cooling only the spaces you need.

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.
