The Longmont80502 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Frozen evaporator coil or ice on the refrigerant lines
Furnace lights then shuts down after a few seconds
Water pooling around the indoor unit or ceiling stains
One or two rooms that never reach the set temperature
Dead or bulging run capacitor on the condenser
Pilot light or hot surface igniter failing repeatedly
Heating and air conditioning service built around Longmont
Homeowners across Longmont call us when the system simply will not keep up. Dry air, wide day-to-night swings and high altitude all change how combustion and refrigerant systems behave. That is why we staff a live dispatch line around the clock instead of routing you to a queue.
Local homeowners often run their system harder than the design intended, especially during June through August. That accelerates wear on contactors, capacitors and blower bearings.
Heating season here is October through April. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Longmont80502 HVAC questions, answered
Are your technicians licensed and insured?
Every technician dispatched into Longmont is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Colorado, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
How often should I change my filter in 80502?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Longmont with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
What does a new system cost in Longmont?
A complete residential replacement in the 80502 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Longmont, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
