"I was referred to Paze Heating and Cooling by a well-respected friend, and I immediately understood why. I have referred this company to several others and will continue to do so. Mr. Zeno Pace and his team are expert technicians. His responsiveness is very timely and his pricing is well worth the level of service he gives. I recently had an A/C problem that was covered by my home warranty company. Mr. Zeno helped me understand and articulate the repairs needed so that I would not be taken advantage of by the other contractor. Ultimately, I was taken advantage of by the other contractor, and Paze Heating and Air came to the rescue. Mr. Zeno responded immediately and fixed the damage the other contractor left. You will not go wrong with Paze Heating and Cooling."

"The technician was on time and courteous.  My A/C wasn't blowing any cold air, so he checked the air handler first, then checked the heat pump.  The freon was very low, 1.5 pounds in a 3.5 pound system, so he charged the unit with freon.  The air was fine after that.  He did a check for leaks from the evaporator coil "on the house" and showed me that the coil was losing coolant from several spots.  He recommended that an engineer come have a look about a system replacement since it was impossible to tell how long the coolant was leaking - the main issue being that the coil had several leaking spots.
Overall the service went well.  The price was a function of the high price of freon ($90 or so per pound), so it could have been any HVAC company getting dinged on the price issue.

Heating and Air Conditioning FAQs, answered by experts

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.
