"Service man arrived as expected and performed the annual maintenance of the air conditioning system. The work was thorough and it was something that was familiar to me as I used to do in my younger years. With heavy use of airconditioning in the summer in CA, this is important and something we do every year.

"I never give reviews but Same Day Heating and Air Conditioning absolutely deserves one, From Start to Finish they were professional, respectful and courteous. The Customer service Representative was accommodating with my busy schedule and was able to send a Tech out later than usual to meet me right after work which I was so grateful for since My kitten and I have been freezing!! I ended up running a little late but my technician Sean was understanding and was such a nice guy. Sean was professional,informative and thoroughly explained all my options to me without being pushy, I've had such bad experiences with Service companies in the past trying to pressure me into buying something or replacing something right away but he didn't do any of that. Hands down best Customer Service I've ever received. Same Day will always be my go to for any of my HVAC Needs. Thank You Same Day. My kitten and I Thank you!! We will never go anywhere else!! :)"

Small jobs welcome

"1} I needed next day service and I'll Handle It did just that. Fit in my need for new disposal asap.
2} Gave me a time frame and fit my schedule. The next morning he called and said he could get there 15 min early which worked out even better for me.
3}Already had the part/disposal needed...actually a couple to choose from. One that was a directly replacement and another that was an upgrade if I wanted it.  No pressure just had options which was terrific!!
4} Completed job in an hour. Great for a job that is paid hourly!!! 
5} Gave me some great advice on maintenance.
6) Offered me his card and suggestions for future jobs which we will definitely call him on!!
Thank you I'll Handle It and Angie's List for being such a great and consistent source for our various needs.

"I am the HOA president of a 50-year-old 85-unit condo complex. Justin, the owner of JP3, is our preferred vendor for the numerous and varied electric repairs and replacements required in an older complex. I also use Justin for smaller repairs in my condo. He is fast and efficient and always does excellent work."

Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

Heating and Air Conditioning FAQs, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.
