"If you want it done right... build it right! Jason and John are great at HVAC, Plumbing, Electrical, basically everything that a 90 year house needs. I have already started recommending them to friends and co-workers. We interviewed 3 different contractors and went through a home warranty recommended contractor before we took the buy out from the insurance company and we picked Built Right. We wanted them to do the work as soon as we had our first consultation because they paid attention to the details of our house better than any of the 4 other professionals that looked at our house. After our first project, we have no issues on our installation and Jason really is committed to making sure we know how to maintain it. We already signed them up for a plumbing project and a small electrical project. 12/10 would do it again."

"Lawrence plumbing replaced an old cast iron drain pipe and repiped all the drains leading into it. Existing drains had to be rerouted to improve flow and move them above the bottom of basement joists. They final product was aesthetically pleasing and they were very professional and they were the lowest quoted cost which did not change."

Heating and Air Conditioning questions, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.
