How often should I replace my filters?
You need to change your filters anywhere from every two weeks to every 90 days. You need to change them more often in the summer or if you have several people and pets living in your home.

Should I have regular maintenance on my HVAC system?
Of course. Regular maintenance is one of the best ways to ensure the longevity of your HVAC unit.

What’s the best way to avoid costly repairs to my heating and air systems?
Like any other mechanical piece of equipment, heating and air conditioning systems require maintenance and occasional parts replacements. Think of it like your car – regular oil changes, occasional brake replacements, and a tune up will keep you safe and on the road. Unlike your car, you and your house depend on your heating and cooling system 24/7 – so keeping it well maintained and repaired when needed will improve the life expectancy and efficiency of your HVAC equipment. Regular HVAC inspections, service, and maintenance by a trained certified technician are by far the best way to avoid expensive breakdowns and repairs.

What's the typical lifespan of an air conditioning unit?
If you get regular maintenance, it will typically last around 13 years. Most air conditioning units will develop issues around year seven or 10.

When do I know that my air conditioning unit needs a repair?
There are several warning signs that will give you the heads-up that you need a new unit. If you're noticing higher energy bills, odd noises, longer cool-down times or weird smells, there's a good chance you need us now for repairs.

Should I repair or replace my HVAC unit?
Sometimes the cost of fixing your current system is so high that it might make sense to invest in a replacement system.
There is no simple solution, but if a repairs would cost roughly $1,500.00 or more and unit is more than 10 years old, it’s might be better to replace it.
Either way, LPZ Mechanical technicians are committed to providing you with the best information and facts to help you make the right decision.

Will a new air conditioning unit save me money?
Yes. Newer A/C units are designed to be more ecofriendly and energy efficient, meaning you'll save on energy bills. Plus, the older your A/C unit is, the less efficiently it runs.

What's the Best Temperature to Set My Thermostat?
Of course, the answer to this question depends on time of the year it is and your specific comfort levels. We have suggestions for the cool and warmer seasons. In the winter months, the average temperature setting is 78°-80°, in the summer 70°-72° seems to be the most common setting. Remember, when leaving your home for work or several hours try to avoid very drastic temperature changes. Do not set your temperature back any more than 5° because this will cause common systems to work harder to achieve the desired temperature setting.

Should I Get My Air Ducts Cleaned?
Allergies and asthma effect more than 41 million Americans. If you’re a part of this group then we highly suggest that you get your air ducts professionally cleaned. This can help your health, your overall breathing, and will likewise give you a more efficient air conditioning system.

Should I replace my ductwork?
Older homes may require updated duct systems. Like everything, duct systems have evolved and improved over time. Each home has its own individual characteristics and requirements. If you have any questions or concerns, call us for a review of your system.

Commercial clients

Yes. We service any tonnage and type of RTU. 

While commercial HVAC systems are far more robust than their residential counterparts, this doesn’t mean they last forever. Their parts age, seams loosen and metal fatigues just like any other system, and often at a quicker pace in a commercial setting. You should consider any commercial HVAC system good for 15 years of use, and a well-maintained system good for 20 years of heavy work.

Your commercial HVAC system moves a lot of air that tends to be dirtier than that handled by a residential unit. Commercial systems should have their filters checked or replaced monthly. Dirty filters not only allow dust and debris to pass, but they impede airflow, causing your system to work much harder.

The constricted airflow has nowhere to go and turns into a tremendous amount of backpressure within the system. This back pressure causes extra wear and tear and results in a shorter lifespan for your system and an increase in needed repairs, both of which harm your bottom line.

Minor air conditioning issues become major problems when you don’t stick to a regular preventative maintenance program. Dirty air filters restrict air flow, making the AC work overtime and causing the compressor or fans to wear out before their time. When service technicians check your system regularly, they can identify and fix issues before they add up to expensive repairs. We recommend tune up every 3 months.

If there’s a refrigerant leak or the level runs low, the HVAC system can’t produce cold air. This results in unpleasant indoor temperatures while the unit works doubly hard to cool the air. If the issue isn’t corrected quickly, it can lead to new and more expensive problems.
