"HVAC machine outside wasn’t working. Ricardo ? was so good at explaining & suggesting his expert ideas. There was a mouse & nest inside the machine & wires were severed. He removed the critter & nest & repaired the wires. All is working again. What a great guy he is!!"

"I called at 2 pm that my furnace would run but blow cold air, no heat. I am disabled land no heat causes me a lot of pain. The dispatcher set appt for 3-3:30 pm. The owner Brett was here by 3:30. He found and fixed the problem by 4 pm. He explained what he had replaced. He was extremely nice. I would recommend Perfect Temp to anyone who needed HVAC work."

"Very professional and great communication. The HVAC Tech answered all my questions, and completed the cleaning and maintenance very quickly. He even took the time to build a p-trap into the drain pipe from the furnace where there hadn't been one, but it definitely should have been there. No more gurgling from the drain pipe anymore. I couldn't ask for more."

Heating and Air Conditioning questions, answered by experts

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.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.
