"A big shout-out to Shawn and his team. He was very knowledgeable, addressed all of our concerns, and made us feel comfortable. We had a full furnace and AC replacement and not only did he make a great offer, but they were on-time, fast and professional. Job well done! I would recommend Porterhouse cooling to everybody who is thinking about some HVAC work."

"This is hard to believe but the HVAC guy that installed the GeoThermal refused to repair it because it was 4 years old. I found Geothermal Specialist through HomeAdvisor, these people got on the repair in less than 24 hours after my call, but also showed me that the Modine Geothermal has a 10 year parts and labor warranty."

Heating and Air Conditioning FAQs, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

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.

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.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.
