"I live in Utah. I went through Home Advisor to find someone to fix Grandma's heat. Grandma said it was 47 degrees in her place. Seaside Air had Grandma's heater fixed in a couple hours. So grateful! Thank you!!!"

They were on time, professional, and had our new heater up and running with just the two scheduled visits. I will certainly use them again when we are ready to have our air conditioner replaced.


I would like to add that we received a call telling us that they would like to come out and take care of a scheduled inspection and service  of our air-conditioner. I told them that I hadn't scheduled that and was then informed that it was complimentary. I scheduled a 7am appointment so that I could leave for work on time. The Tech showed up on time, inspected, cleaned, and serviced our air-conditioner within the time frame that was promised. I was able to get to work on time and the air conditioner is working wonderfully. I have seen a couple of reviews that state they are a bit high priced but I find that you truly get what you pay for. Our heater was wonderful this last winter and the complimentary cleaning and servicing of our air conditioner was just an added bonus. Once again I would very highly recommend them.

  Feb-2016  New update for this wonderful company. We had a complimentary heater inspection and check-up and once again they were able to accommodate my work schedule. They came out early, checked and cleaned, replaced the filter, and got done in time for me to head off to work. They are very professional and I appreciate that.  Thanks again Wightons.

"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."

Air Conditioning FAQs, answered by experts

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
