Question 1

How often should I have my HVAC system serviced in Lehi?

Accepted Answer

We recommend professional service once a year for each system – cooling in the spring before peak season and heating in the fall before the cold arrives. Lehi’s HVAC systems work hard in both directions: five to six months of heating demand from the Wasatch-influenced winters and four to five months of air conditioning use through the Utah summer. Systems that run this heavily benefit significantly from annual maintenance that keeps efficiency high, catches developing problems early, and verifies that safety controls are functioning correctly.

Question 2

What is the average lifespan of an HVAC system in Lehi?

Accepted Answer

A properly maintained central air conditioner typically lasts 15 to 20 years. A furnace, also well-maintained, runs 18 to 25 years in many cases. Boilers often last longer – 25 to 30 years is not unusual for a cast-iron unit that has been properly serviced. Ductless mini splits are generally rated for 15 to 20 years. Lehi systems that run heavily through both summer and winter seasons accumulate operating hours faster than systems in milder climates, so regular maintenance is important for reaching those lifespans.

Question 3

Should I replace both my furnace and AC at the same time in Lehi?

Accepted Answer

If both systems are aging toward the end of their service lives within a few years of each other, replacing them simultaneously makes sense. The indoor coil and air handler are designed to work as a matched system with the outdoor unit, the installation labor has significant overlap, and the two systems are commissioned together. If one system still has 8 to 10 years of life in it, it may make more sense to replace them separately. We give you an honest assessment of both systems when we visit your Lehi home.

Question 4

What filter should I use in my Lehi home’s HVAC system?

Accepted Answer

A good-quality pleated filter in the MERV 8 to 11 range is what we recommend for most Lehi homes. These filters capture enough dust, pollen, and particulates to protect the equipment and improve indoor air quality without restricting airflow to the point where the system struggles to pull adequate air across the heat exchanger or evaporator coil. Very high-MERV filters – MERV 13 and above – can reduce airflow enough to cause problems in systems that were not specifically designed for them.

Question 5

My HVAC system is short cycling. Is that a problem?

Accepted Answer

Yes. Short cycling – where the system starts, runs for a very brief period, and shuts off before completing a full conditioning cycle – is a symptom of a problem, not a quirk. For furnaces, it often indicates a high-limit switch tripping from restricted airflow or a heat exchanger issue. For air conditioners, it can mean refrigerant overcharge, low airflow, or an oversized system that cools the air temperature too quickly without completing humidity removal. Both deserve a professional diagnosis. We see this regularly in Lehi homes where the original system was oversized at installation.

Question 6

Why is my air conditioner running but not cooling my Lehi home?

Accepted Answer

The most common causes are low refrigerant from a leak, a dirty or iced-over evaporator coil, a failed capacitor affecting the compressor or condenser fan, or significant duct leakage sending conditioned air into unconditioned spaces before it reaches the living areas. In Lehi homes where the AC runs heavily from June through September, a combination of factors is sometimes at play. A diagnostic visit identifies the actual cause rather than guessing at parts to replace.

Question 7

How long does a central AC installation take in a Lehi home?

Accepted Answer

Most residential central AC replacements are completed in four to six hours. Jobs requiring electrical panel upgrades, significant line set re-routing, or ductwork modifications take longer. We give you a realistic time expectation after reviewing the specific scope at your home. We do not consider the installation complete until the system has been commissioned and verified under real operating conditions.

Question 8

What size air conditioner does my Lehi home need?

Accepted Answer

The correct size requires a Manual J load calculation based on your home’s square footage, insulation values, window area, ceiling height, orientation, and local design temperatures. Rules of thumb like one ton per certain square footage are not accurate enough for a real installation decision. Lehi homes in the same subdivision can have meaningfully different load calculations based on window placement and insulation quality. We calculate the load for every installation we perform.

Question 9

Is a high-SEER air conditioner worth it in Lehi?

Accepted Answer

For most Lehi homeowners who plan to stay in the home for several years, a higher-efficiency system delivers real savings during a cooling season that runs four to five months. The payback period depends on your specific cooling load, usage patterns, and current electricity rates. We explain the realistic efficiency difference for your specific home and usage situation rather than giving you a generic efficiency pitch.

Question 10

Why is my AC freezing up in Lehi summer?

Accepted Answer

Evaporator coil freezing is almost always caused by either severely restricted airflow – check the air filter first – or low refrigerant charge from a leak. When the coil gets cold enough, moisture in the air freezes on its surface and eventually blocks airflow entirely. If the filter is clean and the system is still icing over, it needs a service call. Running a frozen system causes compressor damage over time.

Question 11

What are the most common furnace repairs in Lehi homes?

Accepted Answer

Flame sensor cleaning or replacement, igniter failure, and capacitor replacement on the blower motor are the three most frequent furnace repairs we perform in Lehi. All three are normal wear items that appear at predictable intervals in systems that are being used regularly. A dirty flame sensor causes the furnace to shut down immediately after ignition because the safety circuit cannot confirm the burner is lit. Igniter failure prevents ignition from happening at all. Both are straightforward repairs once correctly diagnosed.

Question 12

My furnace keeps shutting off shortly after starting. What is wrong?

Accepted Answer

Short cycling in a furnace has several possible causes. A dirty flame sensor is the most common – it causes the system to shut down within seconds of igniting because the safety circuit cannot confirm the flame is stable. A tripping high-limit switch from restricted airflow is another frequent cause, often related to a clogged filter or blocked return air. Pressure switch faults, a failed inducer motor, and heat exchanger issues can also cause this symptom. The correct repair depends entirely on which of these is actually present.

Question 13

How do I know when my furnace needs replacement in Lehi rather than repair?

Accepted Answer

System age, repair history, and the specific failure mode together determine whether repair or replacement is the better option. A furnace over 15–18 years old with repeated repairs, a cracked heat exchanger, or major component failures is usually better replaced than repaired again. We give Lehi homeowners an honest assessment of both repair and replacement options based on the actual condition of the equipment, not a bias toward whichever generates more work for us.

Question 14

Why does my boiler keep losing pressure in Lehi?

Accepted Answer

Recurring pressure loss points to one of three sources: a small leak in the distribution piping or at a fitting, a waterlogged expansion tank that cannot absorb normal pressure fluctuations and forces water out through the pressure relief valve, or a fill valve that is failing to maintain correct system pressure. Sometimes multiple factors are present simultaneously. We trace the source methodically rather than replacing parts without confirming the actual cause.

Question 15

What is that banging noise from my boiler during operation?

Accepted Answer

Kettling – the banging, rumbling, or boiling sound a boiler makes during operation – is usually caused by limescale or sludge buildup on the heat exchanger surfaces. When water contacts heavily scaled surfaces, it can flash briefly to steam and create the characteristic sound. A power flush of the system followed by appropriate inhibitor treatment often resolves this without equipment replacement. In severe cases, the scale buildup may have caused enough heat exchanger damage to make replacement the more appropriate step.

Question 16

Do you service older cast-iron boilers in the Lehi area?

Accepted Answer

Yes. Cast-iron boilers are well-built systems that can provide reliable service for many years beyond what might be assumed. We assess the actual condition of the heat exchanger, combustion efficiency, and key components when we service an older system in Lehi and give you an honest evaluation of its remaining service life. Many older boilers in established Lehi neighborhoods are worth maintaining rather than replacing prematurely.

Question 17

What is the difference between a condensing boiler and a standard boiler?

Accepted Answer

A standard atmospheric boiler exhausts at high temperatures through a metal flue, achieving roughly 80 to 85 percent efficiency. A condensing boiler extracts additional heat from exhaust gases until they cool enough to condense, achieving 90 to 98 percent efficiency, and vents through PVC pipe. For a Lehi home that relies on a boiler as its primary heat source through five to six months of winter, the efficiency difference between these two system types produces meaningful annual savings.

Question 18

Where do ductless mini splits work best in Lehi homes?

Accepted Answer

Ductless systems are ideal for spaces that fall outside the reach of a central duct system: home additions, finished basements, converted garages, detached workshops, and individual rooms where occupancy patterns or sun exposure create demand that the central system cannot adequately meet. They are also a practical whole-home solution for older Lehi homes where adding ductwork would require significant structural work. We assess each situation individually and recommend the system that fits the space and the usage pattern.

Question 19

Why is my ductless mini split dripping water inside the house?

Accepted Answer

Water dripping from the indoor air handler almost always indicates a blocked condensate drain. The unit removes moisture from the air during cooling operation, and that condensate drains continuously through a small tube. When that tube becomes blocked with algae, debris, or mineral buildup, the drain pan overflows onto whatever is below it. This is a common issue and typically a straightforward repair when addressed promptly.

Question 20

Can a ductless mini split heat my Lehi home in winter?

Accepted Answer

Most ductless mini splits are heat pump systems that provide both heating and cooling. Modern cold-climate models can extract useful heat from outdoor air down to temperatures well below freezing, making them a genuinely viable heating source for most of Lehi’s winter. On the coldest stretches – single-digit nights with wind chill – supplemental heat from a backup source may be needed. We factor in Lehi’s actual climate conditions when sizing and recommending ductless systems for heating applications.

Question 21

How long does a ductless mini split installation take in Lehi?

Accepted Answer

A single-zone installation typically takes three to five hours from arrival to system commissioning. Multi-zone systems or installations with challenging line set routing take longer. The refrigerant charge must be precisely set after installation, and we do not rush that step – an improperly charged ductless system delivers lower performance and shorter compressor life regardless of how cleanly everything else was installed.

Question 22

What should I do when my furnace stops working in the middle of the night in Lehi?

Accepted Answer

Start with the basics: check the thermostat settings and batteries, confirm the circuit breaker has not tripped, and verify the air filter is not completely blocked. If none of those are the issue, reach out to us for emergency service. While waiting, close off unused rooms to concentrate available heat, open cabinet doors under sinks if temperatures are dropping toward freezing to protect pipes, and keep family members in the warmest part of the home. Do not attempt to disassemble or restart a furnace that is making unusual sounds or smells.

Question 23

Is a completely failed AC in Lehi in July an emergency?

Accepted Answer

If the household includes young children, elderly residents, or anyone with a health condition affected by heat, yes – this is a genuine emergency that we prioritize accordingly. Indoor temperatures in a Lehi home without AC during a heat event can climb quickly, and overnight temperatures in July rarely drop enough to provide meaningful relief. Contact us today with your situation so we can assess the urgency correctly.

Question 24

Question 25

What if my CO detector goes off and it seems related to my furnace?

Accepted Answer

If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company. For a CO alarm without a gas smell, evacuate the home, leave doors open, and call 911 from outside. The fire department will check CO levels and clear the home before re-entry. Call us after the immediate safety situation is resolved to inspect the furnace before it is restarted. A CO alarm in conjunction with a running furnace is a serious safety concern that requires professional evaluation.
