"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

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

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.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.
