"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.

With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"Tarpy was recommended to me by an electrical contractor I trust. Scott spent the time needed to go over all options for repairing or replacing my old system. I decided to go with a full replacement, and to install new mini-split systems throughout the house. Bowen did a great job working through some tough challenges to work the cleanest install possible. We needed to make a few changes to the install plan along the way and, to his credit, the owner, Broc, stepped up and worked out a fair way to get the job done and done right. Jessica was patient and thorough with the followup paperwork. All in all, a great team, I highly recommend Tarpy, they're an honorable team that delivers on what they promise to do."

"Mega Power was great! I hired them to go solar on my house and the solar analyst that came out was very helpful from day one. He was not just simply a sales guy he gave me his personal cell phone that I was able to call anytime if I had questions or wanted updates about my project.
My project was about 6 kW and consisted of 22 panels, each panel was 275 Watts. What I loved about these guys is that all the products they installed were American made products, warrantied for 25 years! Working with Jonathan (our sales guy) was another reason I chose to go with Mega Power. Every step of the way Jonathan was informative, and just professional from day 1. Price quotes with other companies were similar, so I simply chose the company that provided me the best service before signing anything."

"Two people came on time and worked very hard to finish timely.  They are one of the most professionals we've encountered and also very friendly.  They did an excellent job and we thought the price was more than fair.  They talk to us about what to use and what not to use to clean dirty spots on our bedroom carpets.  We have two very active dogs so our carpets get dirty easily.  We will definitely use them again.  Thank you Monster Steamers!  Jones

"The HERS audit consisted of a home inspection that mapped the exterior, listed all appliances, HVAC, Water heater, etc. They also performed and Door Pressure Test and Duct Leakage Tests. All these figures were placed in a computer model and the output was provided to me in 2 reports, an existing state and the impact of recommended changed on a future state. 
The testing procedures were interesting but the reports are the what you are really paying for. I my case my newer home was relatively efficient and the recommend changes addressed my comfort level concerns, but were all relatively expensive. Per the model, a majority of my electrical expenses are associated with my appliances, so energy savings were comparatively minimal.
Recommendations and Costs
1) Convert to "conditioned" attic space, requiring the installation of closed cell foam in the rafters of the attic and the removal of all existing batt insulation (~$7,00)
2) Install an ERV whole house ventilation system to provide continuous fresh air
3) Replace 5 existing double pane windows with 5 new triple pane windows (~$2,500)
4) Install open cell foam insulation in my south facing walls (~$3,500) when you include repair and paint walls
These recommendations will dramatically improve the comfort in the upstairs, but ultimately energy saving paybacks are many years. I plan to implement recommendations #1 and #2. I also plan to install Solar to stabilize my electrical bills.
Jim, the owner of Healthyhomes4u was great. He answered all of my questions and helped me to prioritize my home efficiency improvement projects."

"I'm very happy with the work that was done by Landmark construction and energy crew. At first, we met with Ron that came over and met with us about the issues that we had with our water heater and with the bills that we currently pay for electric. Ron recommended us to replace the bulky old water heater and to install a tankless system that will supply hot water immediately and with the use of less gas. We liked that idea and we decided to go for this project. Ron came over to our house with his 2 people that basically took care of all the removal and the installation of the new system. The work that they did took only 2 days from start to finish and now we have more space at the garage, and the bills are much lower than before…."

Install Boiler FAQs, answered by experts

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

Costs depend on issue severity, parts needed, and labor rates.
