Frequently Asked Questions

Should I turn my air conditioning off when I’m not at home?

Keep your air conditioning on, but raise the thermostat by 2 to 3 degrees. Turning your AC off and readjusting hours later by 3+ degrees takes much more energy and adds a sticker shock to your utility bill. Consider programmable thermostats, which can automatically regulate your HVAC system. Get in touch for programmable thermostat installation services.

Should I turn my air conditioning off during an electrical storm?

Turning your HVAC equipment off is not necessary because it’s not helpful.  HVAC systems are susceptible to especially high power surges during electrical storms and construction in the neighborhood.  Usually, if this happens, you will experience a “nuisance trip” of your circuit breaker.  However, they can cause failures in your system as well.  Contact Mike’s Air to install a primary surge protector on your system for additional protection.

How often should I have my air conditioner and heater checked?

We recommend twice a year, before summer and winter, when breakdowns are most likely to occur. Routine maintenance costs pennies a day and can save homeowners thousands of dollars in emergency repair costs. Mike’s Maintenance Program is a preventative program for year-round HVAC care.

How long should an air-conditioning unit last?

The lifespan of an AC unit varies depending on its environment. For example, a unit in Texas, where the weather is very demanding, has a life expectancy of 8 to 10 years. Performing regular maintenance and check-ups can improve your unit’s life by years more and save hefty costs on unexpected repair bills. Mike’s Maintenance Program covers two certified Maintenance Visits per year and provides discounted Emergency Service.

My system is brand new with a warranty. Why should I cover myself with a maintenance plan?

System warranties only cover operating parts, not regular maintenance or dirty filters. Your HVAC unit requires the same routine upkeep and maintenance as your car — system coils need to be maintained and cleaned regularly; maintenance components need to be checked and replaced to prevent more expensive motors from failing; and so on. Keeping your brand new system running like brand new requires regular maintenance.
Typically the warranty on your equipment may be voided if lack of maintenance contributes to an equipment failure. Mike’s Maintenance Program complies with and supports the manufacturer’s warranty on your HVAC equipment.

Will I save money if I close the vents in rooms I’m not using?

We don’t recommend closing vents in your home. Savings from doing so are marginal, but the side effects of blocking airflow can be significant — unbalanced air flow causes humidity to rise and become uncomfortable. To properly control the airflow throughout your home and allow your system to cool efficiently, get in touch with Mike’s.

How often should the filter be changed?

When it’s dirty, meaning you have to check your filter regularly. Depending on the type of filter and its application, its lifespan ranges from once a month up to once a year. When in doubt, change it! Keel your filters clean and your system will operate efficiently.

How long does refrigerant last?

Forever — refrigerant does not dissipate! Loss is only caused through a leak somewhere in the refrigerant system. If you suspect a leak in your system, get in touch for repair.
