"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."

"This is our second year in our home and we realized last winter that our backroom addition had little-to-no heat flow and was frigid cold. Our goal was to make that room usable year-round. We bid with two other HVAC contractors and we pulled the trigger with Jim and his team. What put them apart was that they took their time assessing our home and situation, walked through all possible options, and clearly communicated those options. They evaluated and wanted to find the most feasible option for us, with efficiency and cost in mind. The other contractors came through and kind of already had their minds set on what heating system to use. Jim is also very personable, knowledgeable, and easy to communicate with. Jim and Carlton's proposal was the most cost effective overall - the unit/system itself and our personal ROI. It was gas as opposed to electric, the job was the least complex in terms of labor and construction, and it's functionality was worth the price."

"I needed a new HVAC. I received a prompt bid at an extremely favorable price. The technicians who installed my new unit were extremely knowledgeable and personable! They finished the job in one day, even though they had estimated it would take two whole days. They cleaned up after themselves in a marvelous way."

Heating and Air Conditioning FAQs, answered by experts

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
