"Paso Robles Heating and Air Conditioning deserves the highest rating over all others.  We obtained 5 bids on our project and only Paso Robles HVAC provided a quality analysis of the products that would work best for our house and of the work that would be required at a reasonable price.  Therefore we contracted with them to install our new HVAC system.
We worked closely with the owner/manager throughout the process. He was just great!  Highly knowledgable and experienced.
The work was scheduled and they arrived on time and completed the job as scheduled.  The workers were very professional.
They new system has been in place since Nov. 2012.  We have much lower gas bills and the new A/C worked beautifully.   Finally our house maintained a comfortable temperation even through a very hot Summer followed by a very cold winter. 
They also follow-up on their work and have made two no charge service visits to check on the system,  change filters, and do any needed adjustments.
I highly recommend them.  
It is so hard to find a quality contractor, but we really were lucky to have found Paso Robles Heating and Air Conditioning.

"It was installed with a kink in the condensation hose and was not aware that it leaked under our hallway wood floor. This was June 2022. I paid to have a leak detection company come out and say the floor was OK. In August 2022, we ran HVAC for a couple of days during the heat wave and water came out of the HVAC unit, ruining our hallway wood floor. It is 10/29/2022 and we still have not heard from their office on how they are going to fix our floor."

"This was our first experience using Wighton’s and it won’t be the last. Aaron was very professional and very nice to work with. Our air conditioner stopped working and he was able to fix it and did some maintenance work on the unit also. He also pointed out that we needed to replace the air filter which services our hvac system, which we were grateful that he did because we had never had it changed out with a new one and it was long overdue. We signed up for their maintenance program so that our ac/heating will be inspected and maintained on a regular basis. We are very happy with his work and highly recommend Wighton’s!"

"I not only had an old furnace replaced but also had whole house air conditioning added. Very professional family business. Their estimate beat out two other HVAC businesses here in Lompoc⠦⠦ one of them by thousands of dollars. It paid to get three estimates. Daniel was easy to work with and honest. One of the other HVAC businesses in Lompoc is interested in selling you all kinds of stuff that increased his estimate by thousands of dollars. I highly recommend Ace Heating & AC."

Heating and Air Conditioning FAQs, answered by experts

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.
