"Porterhouse Heating and Cooling was very professional and knowledgeable on the service provided. I used them to install my air conditioner unit. Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"Chose him due to the reviews and the price was right for my budget. The contractor who did the installation was good. Only thing I didn’t like was the fishing tactics like Mr Jackson was willing to upgrade the thermostat but after furnace was installed, nope. He said one I had was still good. Also the bullying to put in the reviews for the company. See that’s why he got 5 stars."

"Climate Master is great! They are honest, flexible, and on top of every detail. Just before the holidays our 20 year old furnace went out. The team at Climate Master gave us a second opinion, more choices around payment, and got us back up and running through the holidays until their crew could come out and replace our old furnace and A/C with new units. Without their help, our holidays would have been miserably cold. They put in a state of the art 2-stage Bryant Furnace and AC with IoT Thermostat. They also included all the rebate paperwork to make it super easy."

"From the time that Jason came out to the house to take measurements and explain the options to the time that the installers were finished, everything was very professional and top notch. The work was done in a neat and expert manner. Even my friend, who was an HVAC guy for over 50 years, commented on the fine work."

Install Boiler FAQs, answered by experts

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
