"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."

Heating and Air Conditioning FAQs, answered by experts

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.
