"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

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.
