"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."

"Best in the business. Art did quality work at a fair price over several visits for me. I cannot say enough about the honesty and professionalism he exhibited. Discovery is the best HVAV firm I have ever used. This matters. Being a professional woman means nothing to some folks. Some firms see a woman and take advantage. That did not happen here. I am a 30 year homeowner. Like you, I am just looking for an honorable service partner to handle the systems in my home. It is a puzzle until you find a great partner to help you run your systems. HVAC systems can be a matter of life and death. I had Art out after a flooded basement to check the furnace. Fair price, good advice on that event. Later, I had my furnace motor go out. Art came and replaced it in a very professional manner and at a very fair price. Hey, we can all go on line and figure out what a part costs. Discovery and Art were fair and gave me tremendous peace of mind. My heat is on right now and it is perfect. I got a price for my cooling that I will replace in the spring with Discovery. Why? They are fair, professional, knowledgeable, and have shown me a track record excellence. For women who have been ripped off, I would especially recommend this service. Ask for Art. I heartily recommend Art and Discovery for your HVAC needs."

Heating and Air Conditioning questions, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.
