Our Most Frequently Asked Questions & Answers

We do our best to respond as quickly as we can, especially when there is no heat or serious comfort issues. The exact timing depends on the season, current workload, and your location in relation to other scheduled calls, and we will be honest with you about available appointment times when you call. In colder weather, we generally prioritize homes that have lost most or all of their heating and situations that could affect safety. If we cannot get there right away, we can often talk through temporary steps you can take to stay as comfortable as possible until we arrive.

Before you call, it can help to do a few simple checks if you feel comfortable doing them. Make sure your thermostat or remote is set to the right mode and temperature, check that the indoor filters are clean, and look around the outdoor unit to see that it is not blocked by snow, leaves, or debris. You can also glance at your electrical panel to see if any breakers have tripped that feed the system. If at any point you see sparks, smell burning, or find that a breaker trips again after you reset it once, switch the system off and leave it off until we can take a look. 

We repair Mitsubishi heat pumps on a regular basis, and many issues can be addressed without replacing the entire system. As Mitsubishi Electric Diamond Elite Contractors, we have direct training on their equipment and access to technical support and appropriate parts, which helps us diagnose and fix brand-specific problems more effectively. Whether a repair or replacement makes more sense depends on the age and condition of your system, the type of problem we find, and how often the unit has needed work in the past. Once we have inspected your system, we will explain what we see, outline repair options if they are reasonable, and talk through what a replacement might look like so you can compare both options.

The cost of a heat pump repair can vary quite a bit depending on what is causing the problem and which parts or adjustments are needed. Some issues are relatively simple and can be resolved with cleaning, adjustments, or basic component replacement, while others involve more complex parts or extended labor time. When we come to your home, we focus first on understanding the problem and confirming what is actually wrong. Once we know that, we review the recommended repair, explain what is involved, and go over pricing before we start any work so you can decide how you want to proceed.

Some heat pump issues are mostly mechanical, some are mostly electrical, and many involve a bit of both. Tripped breakers, loose connections, or aging wiring can cause intermittent shut-offs, strange behavior, or complete loss of power to your indoor or outdoor unit. Because D.A. Cressey provides both heating and electric services, we can look at the equipment and the electrical supply in the same visit, which helps avoid gaps between trades. During a service call, we check for mechanical problems and also look at breakers, disconnects, and visible wiring so we can identify whether electrical issues are part of the picture and address them safely and within code.

Working with a qualified contractor is one of the best ways to protect any warranty you may have on a Mitsubishi heat pump. As Mitsubishi Electric Diamond Elite Contractors, we follow manufacturer guidelines for installation and service, and use appropriate parts and procedures when working on these systems. Whether a specific repair is covered by warranty depends on factors such as your system’s age, how it was installed, and the terms of the warranty itself. When we talk on site, we can help you review the basic information you have and explain how the work we recommend fits with Mitsubishi’s general expectations, and we can discuss extended warranty options where they apply.

Energy efficiency is always part of the conversation when we look at a heat pump. As an Efficiency Maine Qualified Partner, we stay informed about program standards and the types of equipment and practices that support Maine’s efficiency goals. When we recommend repairs or, if appropriate, potential upgrades, we keep operating costs and efficiency in mind so you can consider both comfort and long-term energy use. Specific Efficiency Maine incentives or program approvals depend on your equipment choices and program rules at the time, so while we cannot promise particular benefits, we can help you think through options that align with efficient heating and cooling in our state.
