I started "I'll Handle It" to address what I recognized as a need that homeowners have for competent, knowledgeable and courteous home improvement service professionals to help them with all manner of projects large and small. Founded in San Diego, "I'll Handle It" is a home grown business that prides itself in its responsiveness to its customers needs. At "I'll Handle It" "Professional Service You Can Rely on" is our mantra, and we can prove it.

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

"Just had AireCare replace our furnace and A/C. The owner, Michael Santana and his team did a great job at a very competitive price. Repairing my old A/C was just not cost effective. The new high-efficiency heat pump works great and is so very quiet. Michael's crew were very professional, polite and responsive to our requests. They finished the job on the hottest day of the year in less than 8 hours. I highly recommend them. "

Heating and Air Conditioning questions, answered by experts

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.
