"Two visits and that's not our fault: Brian came, diagnosed the problem (capacitor if not blower died, and tune up). He was right: a new capacitor made it work well, until the old blower just refused to obey. Two days later we called and said that Brian was right: the blower needed replacement. Doing just the capacitor was our call to try to save money. Now our 20+ year old furnace runs like new. And I'll be calling them to replace our HVAC ('cuz it's 20+ years old) when it decides to give up the ghost."

"I talked to Nick who was good enough to send a technician out the very same day that I scheduled the service. The technician, Dan, was very prompt, thorough and friendly. He cleaned and sanitized 10+ vents, HVAC system, returns, supply lines, main line, and the dryer vent which was on the roof. A lot of Groupon deals that I looked around for have up-charges for the requirements that I had, particularly since I live in a 3rd floor walk-up in the city. With Lowe's the price that was quoted was the price that I got! I will definitely use their services again!"

"The owner of Guardian Heating and Cooling, LLC (Steve Peterson) and one of his sons (Adam) did an AWESOME job installing a new, high-efficiency, gas-fired Laars combi-boiler at my residence! If the new unit continues to perform as well as it is presently, and Guardian service continues to be this excellent in the years ahead, I will be a happy camper and pat myself on the back for having been smart enough to hire them. :-) The unit they replaced was built by a highly-regarded manufacturer that had been installed by another highly regarded contractor by the previous owners of my home. As it turned out, the previous heating unit was a money pit and the previous contractors technical abilities left much to be desired. Each heating season, the previous boiler experienced one significant failure after another. The previous contractor kept changing parts without digging into **why** the parts were failing. They simply said I should accept this, since the unit was **old**. Unhappy with this response, I decided to cut my losses. To the rescue: Guardian Heating and Cooling! While not the least expensive contractor, Steve, and Son exceeded my expectations simply by meeting them! They arrived one time and did everything they said they were going to do. With unseasonably cold weather in October, I was initially a bit apprehensive at the prospect of having no heat for a few days while a replacement system was installed. I wondered if they would be able to complete this project in a timely manner, as they said they would. My worries were for naught. There were no surprises and no surprise expenses ... no nickle-and-diming when Guardian needed an extra part or fitting ... no drama. Guardian simply got the job done. And they did it beautifully. They took care to minimize the time I would be without water and without heat. After installation, they thoroughly tested the unit. The next day, they checked back to ensure that I was satisfied with its performance. They also cleaned up reasonably when they were done and were carefully not to damage my property, as they moved large, heavy pieces of equipment and tools around. In summary: a big Thumbs Up for Guardian heating and Cooling, LLC!"

"Quick personal response to my initial request. All other vendors responded with generic email, or automated call/voicemail. Josh was to the point, yet personable. He arrived with Kevin and took care of my situation in a fast and professional manner. Felt very comfortable during the entire process! Do your self a favor and call Josh for all your HVAC ne"

"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

Heating and Air Conditioning questions, answered by experts

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

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.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.
