Customers say: Quality work
35 years of experience

Full service General Contractor specializing in all aspect of construction, maintenance and repair. We are licensed, bonded and insured. All work comes with 1-2 year warranty. Payments plans are available upon request at 2% interest. We also offer in home instructions for the "do-it-yourselves", at a basic hourly rate. Last but not least also work as a subcontract.

"If I could give zero stars for this company I would. We had our HVAC replaced in May of 2018. Right from the beginning I had issues with Eddie the owner of the company quoting me one thing and then giving me a different price the next time. Both my husband and I felt a little uneasy about Eddie; however, against our better judgment we used him since he came recommended from close friends. After our installation was complete Eddie told my husband and I to call him in one year so he could provide us with our free one time HVAC maintenance. Both my husband and I attempted multiple times to contact Eddie. We both left voicemails and I even texted him at one point. I still have the text to this day that shows it was read. Since the year had passed Eddie refuses to maintenance our HVAC. He says that he never received our messages despite proof. When I asked him if he was calling me a liar he replied, "you are calling yourself a liar." Do not waste your time on this company."

Energy Efficiency Auditing questions, answered by experts

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Costs depend on pipe length, accessibility, and whether additional services are required.
