Answers to Your Heating, Cooling, and Maintenance Questions

Your first visit is intentionally more comprehensive.

Before we can properly maintain a system, we need to understand its current condition and establish a baseline. The initial service allows us to thoroughly evaluate the equipment, identify existing concerns, document important information, and establish a maintenance history.

Once your system has been established with Summit Air & Heat, future maintenance visits are offered at a preferred discounted rate.

Think of the first visit as establishing the foundation. Future visits are about maintaining it.

Once your system has been brought up to our maintenance standards, future maintenance visits are offered at a discounted rate because we already have a service history and baseline information for your equipment.

Think of the first visit as getting your system caught up and properly set up for ongoing maintenance. After that, regular maintenance is simpler, faster, and more affordable.

Regular maintenance helps keep your heating and cooling system operating safely, efficiently, and reliably. Just like a vehicle needs routine service, your HVAC system benefits from regular inspections and tune-ups to help prevent small issues from becoming expensive repairs.

How often should my HVAC system be maintained?

We recommend having your air conditioning system professionally maintained at least once a year, preferably before the cooling season. Heating systems should also be checked annually before the heating season.

While no maintenance program can guarantee that a component will never fail, regular professional maintenance can help identify worn, deteriorating, or improperly operating components before they develop into larger problems.

Our philosophy is simple:

Find the small concerns before they become big surprises.

A clean and properly adjusted system generally doesn't have to work as hard to maintain your desired temperature. Regular maintenance can help your equipment operate as efficiently as possible and may help reduce unnecessary energy consumption.

It can. Regular inspections, cleaning, and adjustments help reduce unnecessary strain and wear on system components, which may help your equipment last longer.

No. Maintenance is preventative; repairs address existing problems. Maintenance is designed to identify potential issues and keep your system operating properly, while repairs are performed when a component has already failed or the system isn't operating correctly.

If we discover an issue, we'll explain what we found and discuss your options with you before performing additional repair work. There are no surprises—you'll know what we recommend and why.

Absolutely. Older equipment can benefit significantly from regular maintenance because identifying problems early can help you avoid unexpected breakdowns and make informed decisions about repairs versus replacement.

Yes. A system can appear to be working normally while developing problems that aren't immediately noticeable. Preventative maintenance gives us an opportunity to identify those concerns before they affect your comfort or leave you without heating or cooling.

Yes.

A newer HVAC system is a significant investment. Regular maintenance helps you protect that investment from the beginning and gives you a service history that can be valuable throughout the life of the equipment.

The best time to start maintaining your HVAC system is before you need a repair.

We don't believe preventative maintenance should be a quick visit where someone simply checks a few boxes.

Our maintenance approach is built around consistency, documentation, communication, and long-term care.

By continuing your maintenance with Summit Air & Heat, we become familiar with your equipment, its service history, and any developing trends. That allows us to provide a more informed evaluation each time we visit.

It's not just maintenance. It's ongoing care for your home's comfort system.

Contact Summit Air & Heat to schedule your initial maintenance visit. We'll evaluate your system, establish a maintenance baseline, and help you determine the best schedule for keeping your HVAC system running reliably.

Most homes should replace or inspect their filter every 1–3 months, but the right interval depends on the type of filter, household conditions, pets, construction, and system airflow.

A dirty filter can restrict airflow and make your HVAC system work harder.

Several issues can cause this, including:

Dirty air filter

Dirty evaporator or condenser coil

Low refrigerant

Electrical problems

Failed capacitor

Condenser fan problems

Compressor issues

Restricted airflow

Thermostat problems

Because several different problems can produce similar symptoms, a proper diagnosis is important before replacing parts.

A frozen system isn't necessarily caused by "being low on Freon." Possible causes include:

Restricted airflow

Dirty filter

Dirty evaporator coil

Blower problems

Low refrigerant

Refrigerant restriction

Other system problems

Continuing to operate a frozen system can potentially cause additional damage.

Common symptoms include poor cooling, longer run times, ice on the indoor coil or refrigerant line, and increased energy consumption.

However, these symptoms can also be caused by other problems. A technician should properly test the system before determining whether refrigerant is actually needed.

No. Adding refrigerant can restore the system temporarily, but it does not repair the leak.

If refrigerant is repeatedly being added, the system should be properly evaluated to determine where the refrigerant is escaping and what repair options are available.

A properly installed and maintained HVAC system can often provide many years of service, but lifespan depends on equipment quality, installation, usage, maintenance, and operating conditions.

As equipment gets older, the cost and frequency of repairs should be considered alongside efficiency and replacement options.

Repair may make sense when the equipment is relatively young, the repair is straightforward, and the system has otherwise been reliable.

Replacement may be worth considering when the equipment is older, repairs are becoming frequent or expensive, efficiency is poor, or a major component such as a compressor or heat exchanger has failed.

We believe customers should understand their options rather than being pressured into replacement.

Some signs include:

Frequent breakdowns

Rising energy bills

Uneven temperatures

Increasing repair costs

Poor humidity control

Declining comfort

Outdated or inefficient equipment

Major component failure

A professional evaluation can help determine whether repair or replacement makes the most financial sense.

Uneven temperatures can be caused by several things, including:

Poor ductwork

Insufficient airflow

Closed or blocked registers

Duct leaks

Improper system sizing

Insufficient insulation

Building layout

Equipment problems

Replacing the HVAC system isn't always the answer. The underlying cause should first be identified.

A leaking air conditioner is often related to the condensate drainage system, but there can be several causes.

Possible issues include:

Clogged drain line

Dirty drain pan

Damaged drain pan

Condensate pump failure

Frozen evaporator coil

Improper drainage

Ignoring a water leak can lead to property damage, so it's best to address it promptly.

Drain-line maintenance should be performed regularly, particularly in areas with high humidity and during periods of heavy cooling.

A clogged drain can cause water to back up and potentially trigger a safety switch or cause water damage.

There isn't one perfect temperature for every home. A comfortable setting should balance comfort and energy use.

During cooling season, many homeowners find a setting around 75–78°F comfortable, while heating settings are often around 68–72°F.

Using a programmable or smart thermostat can also help reduce unnecessary runtime when nobody is home.

Not necessarily.

An HVAC system should be properly sized for the home. An oversized system can cool the space quickly without running long enough to properly remove humidity, potentially reducing comfort.

Proper sizing is more important than simply choosing the largest system available.
