Comprehensive Heating and Cooling Repairs

You can usually identify when your HVAC unit malfunctions. Look for obvious signs like premature shutdowns or lukewarm air, as well as indirect signs such as unexplained increases in your monthly bill. Some HVAC issues even lead to dirtier indoor air.

You’ll also notice noises. While it’s normal to hear some clicking at the start of a cycle, no noise should linger beyond that. Instead of trying to solve the problem yourself, have one of our technicians take a look at your system. They will provide a correct diagnosis and an accurate cost estimate, with no obligation to hire them.

Sometimes, when older systems require major repairs like a motor replacement, buying a new system proves more cost-effective in the long run. Regardless of the situation, technicians will offer you honest recommendations that prioritize your best interests.

Heating and Air Conditioning Installation

If you own a packaged system that combines a ducted heat pump and a gas furnace, be aware that both systems typically last about 15 years, provided you maintain them regularly. In contrast, oil and electric furnaces can last around 25 years, and mini-splits can operate for up to 30 years. However, eventually, every system will experience a permanent breakdown.

This is where technicians come in to assist you. Heating and air conditioning units function at a specific blowing capacity. If they’re single-speed, it’s essential that the capacity matches your home’s size — it shouldn’t be too strong or too weak. The team will consider these technical details for you. They can also inform you about enhancements like smart thermostats, humidity controls, and zoning controls.

HVAC Maintenance in Saint John

Changing the air filter regularly is important, but it’s just one part of your maintenance routine. A professional should inspect your system and then perform a series of minor repairs and adjustments to ensure the unit runs smoothly during the hottest and coldest months.

Schedule heating maintenance before temperatures drop and cooling maintenance before they rise. On average, tune-ups take between one and two hours. However, the benefits far outweigh any inconvenience. You will face fewer repairs throughout the year, and when repairs are needed, the system’s manufacturer will honor its warranty.

Maintenance can cover the following and more:

• A start-up check, airflow testing, and leak detection
• A check of switches, relays, circuit boards, etc.

• Cleaning for heat pump coils, furnace burners, and more
• Adjustments of loose screws and panels
